I’m reading some reports from CompuTex 2014 right now with a degree of bemusement. Among the slew of new product announcements typical of this event, there’s news from Asus about a new convertible tablet named the Transformer Book T300 Chi that’s billed as “the world’s thinnest 12.5-inch detachable tablet” (quote source: Engadget). At 7.3 mm thick (0.29″) it beats the previous record holder in this interesting category (the Microsoft Surface Pro 3, 9.1 mm) by a significant 1.8 mm (~0.071″).
Last week we saw the SP3 at 9.1 mm; this week it’s the Asus Transformer Book T300 Chi at 7.2 mm; what’s next?
Details on the new offering are still pretty sketchy. According to FirstPost (my best source of such skinny as is available at the moment), we’ve got a device with some kind of Haswell (or possibly Broadwell) “next-gen Core microarchitecture” (undoubtedly of the ULV variety, given the form factor), “up to 128 GB of flash” SSD, 4 GB of DDR3 RAM, and this surprising element “up to 1 TB of storage” (which may mean a hybrid HD, or perhaps an add-in second mSATA SSD). I’m pretty sure it will be available in at least i3 and i5 models, but would be surprised if i7 also joins the mix because the slim package doesn’t leave much room for battery capacity. The keyboard dock is itself quite slender (total width for the device with keyboard and tablet folded together is reported at a mere 14.3 mm, which indicates it’s only 7.1 mm (~0.29″) thick on its own. I have to suspect that doesn’t leave much room for a second internal battery, nor for too many additional ports (from the various photos currently available, there may be one or two USB ports of some kind, possibly a mini DisplayPort, and perhaps a Kensington Lock port, but it’s really hard to tell).
One thing’s for sure: aspiring to be the thinnest tablet is an interesting proposition nowadays, and apparently gives contenders little or no time to rest on their accomplishments before being dethroned. But at 7.2mm, Asus may be in a position where other vendors will be challenged to match them, let alone surpass them. We’ll just have to wait and see about that!
The Llama Mountain motherboard faces one way, the sisterboard the other way, to help heat dissipation. The entire package is just a little bigger than an iPhone. Wow!
[Note added 6/3/2014 10:22 AM: Part of the mystery behind the new Asus tablet is addressed by coverage from Computex that emerged this morning, regarding the so-called "Llama Mountain" prototype laptop from Intel, which provides a reference implementation built around the upcoming Broadwell incarnation of the company's ultra-low voltage Haswell processors, now called the "Core M" (M is for Mobile) line. This is a "die shrink" from 22 to 14 nm of the already-popular Haswell family, and results in a set of mobile processors for which all members enjoy a TDP of under 10 watts. The best Llama Mountain story I've found so far -- and there are already oodles of them out there -- is from TheNextWeb and is entitled "Intel introduces incredibly thin Llama Mountain reference design running Windows 8.1." Among other things, this story reveals that the Asus Transformer Book T300 Chi is indeed based on the Core M processor line, that it's an entirely fanless design, and that Intel's own reference tablet is a mere 7.2mm thick itself. TheNextWeb includes photos of the motherboard (which contains RAM and CPU plus the bulk of the PC's circuitry) and a so-called "sisterboard" that houses SSD storage and the Wi-Fi radio components. The whole package is just slightly bigger than an iPhone (looks like a 4c model from what I can tell from the side-by-side photo). Here's my favorite quote from the story: "Because of the small motherboard, the 12.5 inch tablet can house more batteries. The board is flanked by two batteries that give the device 32 hours of battery life. The tablet without the keyboard is 670 grams and 7.2mm thick. It's thinner than an iPad air but running Windows 8.1 Pro."
My! My! My! Hasn't the tablet scene just suddenly gotten a lot more interesting? I have two thoughts on this: Poor Microsoft, with its triumphant SP3 announcement from last week now completely eclipsed. And is it possible that Apple will finally start feeling some heat from the long-downtrodden PC-derived tablet sector?]
A few months back, I posted a whimsical post right here entitled “Windows 8.1 Bada Bing!?” (March 3, 2014). It not only reported on rumors of a low-cost/no-cost version of Windows 8.1 which turned out to be correct, but speculated that it “…could be offered as an ‘upgrade’ to Windows 7 users who might otherwise be disinclined to migrate to Windows’ upcoming Update 1 release scheduled for April 8 or thereabouts” which turned out to be wrong, wrong, wrong.
Windows spokesguy Brandon LeBlanc explains what Windows with Bing is all about: cheap bits for cheaper low-end PCs.
You can find Mr. LeBlanc’s post on the subject and see for yourself, but these two blue-lined “call-out” points plucked from its content (plus the title of the blog itself) pretty much tell the whole story:
- scale Windows to an even greater number of customers with more partners and new devices at a broader range of price points
- Windows will be available for 0 dollars to our hardware partners
Combine all this happy rhetoric with the retuning of Windows 8.1 Update’s hardware requirements to 16 GB of storage and 2 GB of RAM, and you’ve got some a more competitive recipe for low-end devices that don’t impose a hefty hardware burden on hardware builders, and likewise limit the cost of climbing aboard the Windows wagon to grab some OS bits along the way. Throw in LeBlanc’s remark that “some of these devices, in particular tablets, will also come with Office or a one-year subscription to Office 365″ and the whole thing starts to make sense.
My favorite part of the release: the line where Mr. LeBlanc reminds us that “… more people … will have access to an even broader selection of new devices with all the awesomeness that Windows 8.1 provides, and get Office too…” Who knew? Look out Android: here comes Windows!
When I saw the headline at pocket-lint.com this morning, my first thought was “marketing/advertising spam!” But when I dug a bit more deeply into “SSD breakthrough makes drives 300 per cent faster and 60 percent more power efficient” it actually started making some kind of sense. Here’s the scoop, in the simplest possible terms: SSDs use a complicated method to write data to their storage chips, which basically depends on writing entire “disk blocks” (memory blocks/pages, really) any time new information needs to be recorded. Researchers at Chuo University in Japan have figured out a new method that uses a “logical block address scrambler” to stop data from being written to a new page, and targets it at a block that’s scheduled to be erased in the next garbage collection sweep anyway. This means fewer new pages to write, less copying of data from page to page, and longer drive lifetimes (less writing overall means more time until the so-called “write ceiling” for individual memory locations is reached).
This time, it’s not faster hardware that delivers performance and power gains: it’s smarter software!
The real beauty of this discovery is that it involves only firmware changes and doesn’t require new hardware. Assuming SSD controller makers would be willing to implement these new algorithms (and why would they risk incurring customer ire by refusing to do so?) your next SSD firmware update could be something really special indeed. I’m going to be very curious to see if the big players in this space — Intel, Samsung, Marvell, LSI, and so forth — will ante up and invest in existing products, or if this will become a strictly next-generation-only phenomenon.
This should be an interesting set of developments to watch out for and track, that’s for sure! How often does one get a shot at a threefold speedup, while saving energy at the same time? That’s why my initial take was “Too good to be true!” Only time will tell if that turns out to be the case, not because the speed-up and savings aren’t possible, but because the SSD makers decide not to offer retroactive updates to owners of existing –especially older — SSDs.
[Note added 5/27: Robin Harris, a knowledgeable and tech-savvy writer for ZDNet, posted a story this morning about this research entitled "An SSD speed jump by four-times? Not so fast." He provides more context, including the revelation that the research (unsurprisingly) is based on a simulation of how NAND Flash behaves and works in real devices. He provides some useful analysis, too, and concludes with this "bottom line" remark: "Don't expect to see this impressive speed up in the next three years. Flash vendors have other techniques for speeding flash performance." So indeed, perhaps it was truly "too good to be true!"]
In the wake of Microsoft’s announcement of the new Surface Pro 3 earlier this week, and the blizzard of articles that have followed in its wake, I’m both amused and bemused to understand that things at the upper end of the laptop and tablet marketplace are becoming increasingly blurred. But it’s also the case that the upper end of this market puts the considerations, concerns, and outright obsessions that drive design and critiques for this narrow niche well outside the mainstream. Nobody says this better at the moment, than Paul Thurrott of the Windows SuperSite (who himself has produced a plethora — 10! — articles in the period between May 20 and May 22 taking the Surface 3 as their primary focus) in his recent story entitled “Surface Pro 3: Let’s Talk About the Price.” The subtitle of his story sums up the results of his cogitations: “It’s expensive, yes, but still a good value.”
The key selling points for SP3 are: lighter, bigger screen, better PPI, and improved pen-based UI/interaction.
Thurrott makes some telling points in his cost analysis piece where he observes that pricing a tablet or ultrabook over $1-1.2K puts it outside of the interest zone for many, if not most, casual users. That places the focus of that market on business users (who are essentially spending OPM to get something they might not ordinarily buy for themselves) and high-end consumers (who are well-heeled enough to cover the costs, and conscious enough of the old adage “you get what you pay for” to understand that spending more can also mean getting more — or less, where reducing weight and thickness are concerned — for the outlay). For this market — the same general audience that buys the 13″ MacBook Air, the various MacBook Pro models, the Lenovo X1 Carbon, the Toshiba Kirabook, and so forth — what the Surface Pro 3 brings to the party is at least interesting and possibly compelling to those used to traveling and buying in such circles. For the record, the jury’s still out on usability issues, including what many writers, including Brad Sams of Neowin.net and Microsoft itself, call “lapability” (Sams has already written a story about using the SP3 on a four hour plane ride on his way home yesterday from the announcement in NYC the day before that tackles this subject). The jury’s still out on SP3 battery life, a particularly important characteristic for many prospective buyers, include your humble correspondent.
What about the legions of other people who don’t want to fork out $1,200 or more to get a work-ready model of the SP3? (Note: Thurrott and others rightly spec such a model out with an i5, plus 8 GB of RAM, and a 256 GB SSD or better, with Type Cover, at a suggested retail price of $1,428.) There are still plenty of good options around for those who want a usable Windows 8 tablet, with enough accessories (meaning a good keyboard/cover at a minimum, and better yet, a good docking station for at-the-desk use) to make a well-rounded offering for semi-serious use.
In following this marketspace recently, I’m particularly inclined to call out the Dell Venue 8 and 11 Pro models, plus the newly-announced Lenovo Thinkpad 10. Be sure to look for at least a quad-core Atom CPU — which usually means Z3740 or better, or an i3/i5 in the case of the Dell Venue 11 Pro – 4 GB RAM, and 128 GB SSD if you want to use them more seriously. (Note: the new Thinkpad 10 models won’t be available until June, 2014.) All three are worthy of serious consideration and possible purchase. Better still, all three cost under $1,000 (the i5 Dell Venue 11 Pro model costs $850 at the upper end of the price spectrum, sans any accessories, though) and all will handle light to medium duty Windows use in quasi-laptop-mode as well as working nicely as standalone Windows 8 tablets. For the majority of prospective Windows 8 tablet users who must fund such acquisitions on their own, these options are bound to be much more attractive.
In closing, here’s another perhaps more important question to ponder, in an era of increasingly large Android tablets: What do these offerings portend for the future of Windows tablet computing, when a usable 10″ Android device — such as the Samsung Galaxy Tab 2 or Tab 3 — routinely goes for $300-350?
There’s been quite a bit of coverage over the past few days about a recent announcement from the Chinese government that it will “ban the use of Microsoft’s Windows 8 on its computers” (this quotation comes from Paul Thurrott’s May 20 story from WindowsITPro entitled “China Bans Windows 8 on Governmental Computers“). Reasons for this ban vary according to the source from whence such information originates, and include the following options or alternatives:
1. The government’s own posting on the subject indicates that the ban is in response to a planned move to “energy saving” products, which turns out to mean a home-grown combination of the Linux OS, open source software, and various security enhancements
2. Xinhua, one of the premier Chinese news agencies, reports that the ban is intended “to enhance computer security” in the wake of the end of life (and free support) for Windows XP, of which hundreds of millions of (mostly pirated) copies are in use in China, including in all aspects of government operations
3. On April 22, The Economic Times quoted the deputy director of China’s National Copyright Administration, Yan Xiohong, as saying “Windows 8 is fairly expensive and will increase government procurement costs” but that Chinese authorities are negotiating with MS on this matter. The paper reports further that Windows 8 sells for approximately $142 per license in China at this time.
When combining these various takes on the situation, I find myself wondering if the Chinese government might not be conducting high-stakes price negotiations with Microsoft through the press, while at the same time expressing its pique about the security threats to existing XP installations posed by lack of ongoing support and security updates for that venerable and widely used operating system. On the other hand, it’s also easy to see worries about security backdoors in US information technology products (including software) raised by the ongoing reports from Mr. Snowden. It’s hard to tell if this is a genuine matter of decided policy, or a gambit to ensure a better deal for the hundreds of millions of licenses that the Chinese government might have to buy in the future, if not all of these things at work simultaneously. Interestingly, current reports also indicate that the Chinese government is continuing to buy Windows 7 licenses, at least for the time being. It should be very interesting to see how this all plays out.
For the past couple of weeks rumors have been flying thick and fast that MS will be introducing a new model of the Surface Pro on May 20, 2014, along with the long awaited Surface Mini. I finally picked up some more substantial (though still speculative) “details” about the upcoming release from numerous sources including ZDNet, the Latin Post, and PC Magazine.
No Surface Pro 3 images have leaked yet, so here’s the MS official still for the preceding version.
There are some fascinating elements among the supposed device’s rumored new capabilities, including:
1. Larger screen size: LT indicates 12.9″ at 290 ppi (2,560 x 1,440); other sources put the display around a nominal 12″ and don’t mention resolution
2. A variety of processors form the 14 nm Core “Skylake” family of CPUs, including one i3 model, 2 i5 models, and 2 i7 models with SSD storage of 64 GB, 128 GB, 256 GB, 256 GB, and 512 GB as you climb the performance scale. Memory is 4 GB for the two lowest models, and 8 GB for the three highest ones
3. Price points fall at $799, $999, $1,299, $1,549, and $1,949 likewise ascending the performance scale
4. Wi-fi will reportedly include 802.11 ac coverage on this latest iteration
5. PC Mag reports the concomitant debut of new Type covers for the larger tablet as well (likely accessories for a device designed to do double duty as a laptop/desktop replacement, no doubt)
6. LT speculates battery life of 9 hours for HD video playback, and 15 hours for light-duty surfing and e-mail use. For sure a bigger device provides more room for a bigger battery, but it remains to be seen if this rumor reflects reality or wishful thinking (LT also reported storage up to 1 TB on the Surface Pro 3, and the ultra-high screen resolution; one wonders likewise about such details as well).
But if enough of these rumors turn out to have real substance to back them, I think I may finally find myself willing to plunk down the cash for the lastest Surface Pro model. In fact, what’s reported appears to tick off all the elements from my November 2012 wish list for a business-capable Windows 8 tablet (“Wish List: Windows 8 Tablet Requirements for Business Use,” 11/14/2012). Here’s hoping, then, that the rumors are mostly correct! For the record, I care most about the battery life, next about storage and processing power, and only distantly about Retina-class resolutions.

Microsoft was all about the cloud at this year’s TechEd North America 2014 but IT pros wanted something more down to earth: news and previews about the on-premises System Center Configuration Manager.
This was the first time Microsoft consolidated its annual Microsoft Management Summit (MMS) with TechEd and for many attendees, it was a bit of a letdown.
Even Anderson’s keynote and subsequent demos failed to generate a high level of excitement about the cloud, said an attendee, which set the tone for a much more subdued conference.
Longtime MMS attendees were disappointed at the lack of news surrounding Microsoft’s flagship on-premises System Center Configuration Manger (SCCM).
Instead, the Redmond behemoth focused its attention on encouraging IT pros to move to a hybrid cloud model using Azure, previewing the ability to manage Office 365 using Intune, a new ASP.Net framework and unveiling Azure RemoteApps.
But more importantly, one of the key elements many MMS alumni missed at TechEd was the lack of attention on management topics.
The MMS community represents a more traditional customer and Microsoft wants enterprises to make the shift toward adopting newer cloud technology, said Steven Hosking, a consultant engineer for Vigilant IT based in Australia.
Attendees like JD Young, technology systems engineer for the Tahoma school district in Maple Valley, Washington, said they missed the sense of community surrounding MMS.
That missing feeling has sparked talks of a community-driven MMS conference.
“This would allow a focus on System Center and on-prem solutions, which are still pre-dominant,” said an SCCM administrator for an IT consulting organization based in Massachusetts. “There is a lot of support among MMS alums for this kind of solution. It will be interesting to see where it goes.”
For some seasoned attendees, the classes disappointed.
“Almost every class and everyone is low-key this year,” said one system administrator for a Florida water utility company who requested anonymity, adding many sessions were too general. He did like some SharePoint level 400 classes and technical tips he received from the experts, however.
“It [seemed] disorganized this year,” the system administrator said.
Attendees also wished Microsoft’s new CEO Satya Nadella was the keynote speaker this year to address the IT pro community. Since taking the helm of Microsoft, Nadella has repeatedly voiced his support for IT pros, calling the community the third constituency.
Whether Nadella’s appearance at TechEd might have made a difference for IT pros in how they responded to the conference is “cloudy.” But what is clear is that IT pros still want their on-premises SCCM and they’re looking hard for Microsoft to give them the answers.
Over the past six weeks, Windows watchers have tracked and pondered occasional but vexing issues for some Windows 8.1 users when it comes to applying a key update — namely KB 2919355, originally issued on April 10, then reissued on April 21 or 22 — to their systems. The reason why this particular update matters more than most is that its application is required for Windows 8.1 users to remain able to apply future updates to their systems. To give enterprises time to get ready, MS has also extended the deadline by which time that update MUST be applied to Windows 8 systems until August 12 (that month’s Patch Tuesday) for those who get their updates through Windows Assurance or the Windows Server Update Services (WSUS). Ordinary Windows users were originally given until May 13 to do likewise, but that deadline has now been extended until next month’s Patch Tuesday (June 10).
I’ve already blogged repeatedly on this subject, most recently on May 7 in a post entitled “Continuing Saga of KB2919355 Win81 Update.” In those posts, I’ve also referred to numerous articles from Windows (and MS Office) wizard Woody Leonhard who has himself written repeatedly on this topic for InfoWorld online. Woody’s latest opus on this topic appeared yesterday (May 15), is entitled “Microsoft posts tips for overcoming Windows 8.1 Update KB 2929355 errors,” and goes into considerable detail (with supporting links to a considerable number of resources and details, including MS advice on the topic, along with the most common Windows error codes that affected users are likely to encounter should they experience trouble in getting KB 2919355 to install properly (or at all).
What’s currently missing from the analysis and controversy is a sense of how many Windows users are afflicted with KB 2919355 problems, and what portion of the overall user population they represent. I’ve got 8 Windows 8.1 machines that I maintain (4 desktops, and an equal number of laptops, including three touch-enabled systems) and I haven’t hit serious snags with any of them. Only one of those machines required a reinstallation of KB 2919355 (which concluded successfully following the 4/21 or 22 re-release of that update), and all of them have now made it through the update process without further (or any) difficulties.
Reading through a post on the Microsoft Community forums at answers.Microsoft.com, it’s readily apparent that plenty of people have encountered issues with KB 2919355 (and other, related Windows 8.1 Update components including KB2919422, KB2932046, KB2937592, and KB2938439). In addition, MS has created separate discussion threads for six different error codes, plus the generic error message “We couldn’t complete the updates. Undoing changes. Don’t turn off your computer” as shown here:
If you are receiving the error ‘We couldn’t complete the updates, Undoing changes. Don’t turn off your computer’ please post to this thread found here
If you are receiving Error 0x800F0922 when installing KB 2919355 please post here
If you are receiving Error 0x800F0923 when installing KB 2919355 please post here
If you are receiving Error 0×80070003 when installing KB 2919355 please post here
If you are receiving Error 0×80070005 when installing KB 2919355 please post here
If you are receiving Error 0×80070490 when installing KB 2919355 please post here
If you are receiving Error 0×80073712 when installing KB 2919355 please post here
Preceding italic text comes from Paul Sey’s 5/14/14 post to the MS support forums thread at answers.Microsoft.com.
Some readers of this blog and other coverage of this topic have suggested that the KB 2919355 issues reported here and elsewhere are simply “a tempest in a teapot” and don’t really represent anything serious. I have to disagree, especially for enterprise IT departments faced with deploying the update into carefully managed organizational computing environments. This is just the kind of thing that gives IT pros the heebie-jeebies. The original KB 2919355 forum thread was locked at 103 pages, and another thread on that topic (“KB2919355 (Windows 8.1 Update) Fails…” was likewise capped at 116 pages, so these issues are neither completely out of the ordinary nor easy to solve, either.
I’m going to echo and amplify on Woody’s closing exhortation from his latest article for those who may be encountering issues with KB2919355. First, if you have experienced difficulty that falls into any of the seven categories listed above, follow the respective link to the designated Windows Error code thread provided in the text lifted from Paul Sey’s 5/14/14 forum post above. Second, if your error code isn’t listed there, visit answers.microsoft.com, and search for your error code there. If you can find a thread, post to it; if not, start a new one. Only if the community comes together and chases problems down can they be fixed, and will Microsoft get a complete accounting of unresolved issues still in the wild. This will be necessary to get them to revisit the deadline for applying KB 2919355, both for ordinary users on Windows Update and Microsoft Update, and for enterprise/organization users who get their updates through Software Assurance or WSUS.
[For more news on KB 2919355 from Woody dated 5/16/2014 please visit "Microsoft acknowledges more error, 800700371 and 80071A91, when installing ... KB 2919355." Apparently, the woes continue, and there are still no proven fixes or workarounds available for those suffering from any of the aforecited error codes.]
After much upset and considerable hoopla about potential issues with items in the May 13 Patch Tuesday updates — a considerable collection of 9 separate Security Bulletin IDs in the May 2014 Security Bulletin, that resulted in anywhere from 32 to 35 items in Update History on my various Windows 8.* PCs, and 16-odd items in Update History on Windows 7 machines — installation and subsequent operation seem to be proceeding with nary a hiccup nor complaint from the 10 or so machines in my current stable.
For example, on my primary production machine (an i7-2700K Sandy Bridge build), of the 34 items showing in Update History for 5/13, 16 elements were not related to MS Office — and covered Windows 8.1 itself mostly, with elements for .NET, One Drive, Internet Explorer and Flash, and more — and 18 elements involved security and other updates to Office 2013 or various components thereof. Other machines (which ranged from 32 to 35 elements added in total) showed a similar distribution, with a nearly even split between Office and non-Office elements. Here’s a snapshot of the lengthy list of elements from the aforementioned PC from yesterday:
This time around, there’s a long list of items to ponder from Patch Tuesday (click image for full-size version).
Overall, download size averaged between 900 MB and 1 GB for the various elements involved. With one element optional, and the others all important (more on that next), I elected to download the important elements in a single go, and the optional element in a separate go, which required two reboots to get through the update process completely. On most of my machines, that took about 20 minutes to complete (but YMMV, depending on download speed and how quickly PCs reboot and start up). In fact, a colleague told me that one of her PCs took nearly an hour to chunk all the way through the update process from start to finish.
Interestingly, the item that appears as KB2953522 in the list equates with MS Security Bulletin MS14-029 shows up in the Update History as an “Important” update, but in the May 2014 Security Bulletin it’s listed as “Critical” (Remote Code Execution). I’m not sure what’s going on with this apparent discrepancy, but this is considered a key patching item to avoid known and potential exploits on Windows 8.* PCs (and other current versions of Windows, as it apparently extends to versions of IE from 6 through 11). There had been some speculation that Microsoft would provide an XP patch for this item as well to provide protection beyond the “end of life” date reached last month, but its receives no mention in MS14-029, nor do there seem to be any new “patch bits” available for the now-defunct and unsupported OS through normal channels. Presumably those parties who’ve paid for extended support for XP will have received something, but I’ve seen no news about this so far (MS14-021, which was severe enough to warrant an out-of-band patch released on May 1, 2014, did include XP coverage, however). Larry Seltzer offers some interesting ruminations on this topic late yesterday via ZDNet in a post entitled “Microsoft patches Office, SharePoint and Windows, leaves XP behind” (worth reading). He also covers all the key elements in the latest round of patches and updates.
Thanks to inveterate Windows wizard and toolsmith Sergey Tkachenko, I learned about a new cleanup method for Windows 8.1 Update installs to purge no-longer needed files in the wake of successful update installation (WARNING! If you follow this recipe, you will not be able to roll back from any updates previously installed). By now, almost everybody knows the technique of clicking the “Clean up system files” button in Windows’ Disk Cleanup utility to purge their systems of update files and info in the wake of a Service Pack or similar Windows Updates. This latest take on cleanup uses Microsoft’s Deployment Image Servicing and Management tool, implemented as dism.exe at the command line.
For those who’ve (a) successfully installed KB2919355 and its attendant patches and fixes and (b) are content to go forward under the new Update regime, here’s how to clean up after those updates are applied:
1. Launch an elevated command prompt (there are many ways to do this, but if you type Windows key-X and select Command Prompt (Admin) from the
resulting pop-up menu, that’s about as convenient as it gets in the Windows 8 world).
2. type the following line at the command prompt:
dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase
This command will typically take a few minutes to complete (see following explanation for what it’s doing).
3. Exit command prompt
4. Using File Explorer, delete the contents of the C:\Windows\SoftwareDistribution\Download folder. Because you can’t roll back after the preceding DISM command, there’s no need to keep these files around any more.
What’s Going On in DISM?
According to the TechNet article “DISM Operating System Package Servicing Command-Line Option,” the /Cleanup-Image, /StartComponentCleanup, and /ResetBase options for DISM all fall in the category of switches designed to perform “cleanup or recovery operations on the [Windows] image,” where the /Online option tells DISM to work on the image of Windows 8 that’s currently running. In particular, here’s what’s up with the two final options in the list of DISM arguments:
- /StartComponentCleanup gets rid of any superseded components in the Windows component store (aka the often mysterious WinSXS folder), and thus also reduces the size of the component store itself.
- /ResetBase resets and reorganizes the remaining components in that store, and also helps to reduce the overall size of that component store, essentially by defragmenting its contents and eliminating slack or unused space therein.
The net result can be savings of 1-2 GB in the Windows partition on a typical Windows 8.1 Update install (YMMV in terms of actual numbers). There’s lots more interesting stuff you can do with DISM under the /Cleanup-Image category, so you’ll want to read further in the afore-cited TechNet article to learn more about what’s available to you.
