Minasi Resurrects Microsoft SteadyState for Free

Ed Tittel Ed Tittel Profile: Ed Tittel

Thanks to an InfoWorld article by J. Peter Bruzzese entitled “How to snapshot Windows 7 and resurrect SteadyState — for free” I just learned that well-known Windows guru Mark Minasi (long-time Sybex author of all those many Mastering Windows books over the past 20 years) has resurrected an obsolete but valuable Windows facility. This facility is called SteadyState, and it enables Windows to return to a pre-defined state each time a system is rebooted. This made SteadyState a staple for admins who worked in schools, computer labs, libraries, or with kiosk machines, because it guarantees that a new user will encounter a clean, pristine Windows installation each time the system reboots, no matter what the previous user may have done with or to that machine.

Alas, Microsoft discontinued SteadyState in December of 2010, and Microsoft let support for this facility lapse entirely on July 1, 2011. There are, in fact, numerous commercial products that still do what SteadyState used to — Bruzzese identifies three named Deep Freeze, Time Freeze, and Returnil in his InfoWorld story — but at around $40 per seat, such costs may be beyond the means of the core audience for the old SteadyState stuff.

Minasi has created a total bare-bones Website called where he provides a zip file that contains a detailed step-by step description of how to roll your own version of SteadyState along with all the files needed to put this environment together for yourself (along with licensed system components, of course). For the technically curious, it works by booting first to the Windows pre-installation environment (aka WinPE) which then loads a pre-defined VHD for the pristine system image that this tutorial teaches you how to construct.

There is one caveat that Bruzzese points out in his story worth attending to. Because Microsoft does not allow Windows 7 Professional to manipulate bootable VHDs, you cannot use this technique with machines running that version of Windows 7. It only works with Windows 7 Enterprise and Ultimate versions. Nevertheless, this is a great bit of public service from Mr. Minasi, and I’d like to add my thanks to him to Mr. Bruzzese’s while also thanking Mr. Bruzzese for bringing this effort to my attention and for his useful commentary and analysis of what Mr. Minasi did. Thanks guys!

Windows 8 Memory Optimization Sheds Light on Interesting Internals

Ed Tittel Ed Tittel Profile: Ed Tittel

There’s a fascinating new post up on the Building Windows 8 Blog from Steven Sinofsky, dated October 7, 2011. It’s entitled “Reducing runtime memory in Windows 8”, and it digs into lots of interesting tricks and techniques that Microsoft is using to bring down memory consumption for Windows 8 overall, and to make best use of available memory even on devices equipped with as little as 1 GB of RAM.

Here’s an example of the kinds of insights this blog post contains “…minimizing memory usage on low-power platforms can prolong battery life.” That’s because RAM consumes power all the time it’s in use, so “…the more RAM you have on board, the more power it uses, [and] the less battery life you get.” Sure, I knew that from a simple energy consumption basis, but I’d never really put it in those terms before, probably because my computing universe has hitherto assumed a constant supply of power from a wall circuit rather than a limited reservoir of battery-based juice.

Other interesting tidbits in this posting include how designers used “memory combining” so the Windows memory manager could identify duplicate bits of data or information, then store them only once, instead of as many times as the OS and applications choose to store them (any time such info is written to, a private copy is created and allocated to prevent inconsistencies). Another trick is to change services so that they start only when they’re used, and consume memory and other system resources only IF they’re used. Old fashioned usage and visitation analysis applied to memory also let MS observe memory usage, and allocate runtime memory only for things likely to be referenced and used sooner rather than later. This plays into a more strategic notion of memory prioritization (what to keep resident and what to swap out after a period of inactivity) that helps the OS make better use of available physical RAM. And finally, given the differences between the Metro UI and the older desktop UI in Windows 8, the OS can defer memory allocation and use for desktop UI stuff only when it’s needed rather than automatically upon system startup. This, too, affords some useful savings (23 MB, according to the blog post, for the current preview version of Windows 8).

All in all this adds up to some interesting memory savings and optimization, and also explains somewhat more of how Windows 8 internals function, and how they compare to Windows 7. It’s starting to look like MS is taking the whole mobile device aspect of things very, very seriously!

It’s “Goodbye Gadgets” for Windows 8!

Ed Tittel Ed Tittel Profile: Ed Tittel

Dang! I just stumbled across another pending change coming with Windows 8, and I’m sorry to say I’m not too thrilled about it, either. It seems that the Metro UI doesn’t make room for Windows Gadget displays. In fact, you can read a post at the Windows Live Gallery that includes the following quote “Microsoft is no longer supporting development or uploading of new Gadgets.” (for the Windows Live Gallery, anyway). Here’s a screencap of the Windows Live Gallery page as it currently stands:

No more gadgets in Windows 8

No more gadgets in Windows 8

In discussing this subject in an article for Network World (“Windows 8 Means no More Widgets or Start Menu“), author Andry Patrizio opines that he “… never knew anyone who used them…” (gadgets, that is). Well, I for one have found a certain class of gadgets invaluable for system activity and health monitoring. I regularly use Microsoft’s Clock gadget, which puts an instantly readable clock face on my screen (yeah, I know I can look down at the digital readout for Date/Time at the lower right in the notification tray, but I can tell what time it is much more quickly from a clock face, and see it from much further away). I am also extremely fond of All CPU Meter and Network Meter from, regularly use the Norton Internet Security desktop gadget, and love the Windows Vista Shutdown Control Gadget, OS designation notwithstanding, because it lets me restart or shutdown my PC quickly and easily.

I sure hope some mechanism for accessing handy little management and control applets persists into Windows 8. They may not be called gadgets anymore, but I sure hope they remain available!

“The End of Patch Tuesday” for Windows Server 8?

Ed Tittel Ed Tittel Profile: Ed Tittel

I had a fascinating phone conversation with Executive Editor Ed Scannell at TechTarget yesterday, who clued me into one very interesting facet of his recent trip to Redmond for a sneak preview of the coming version of Windows Server (which everybody is calling Windows Server 8 these days, even if it will undoubtedly be called Windows Server 2012 by the time it ships). Amidst our discussion of interesting rumors and suppositions–such as, for example, the notion that Windows 8 desktop may precede the release of Windows 8 Server by as much as six month, with perhaps an early release for ARM and a later x86 release to jump on smartphone and tablet opportunities–he revealed to me that Windows 8 will include a facility known as “Cluster Aware Update” which works with an eponymous wizard called the Cluster Aware Update Wizard, or CAUW (I want to pronounce this “cow”, but the word on the street is that this is “not cow”).

Apparently, there was some loose talk about how this tool could make Patch Tuesday updates a thing of the past for server administrators, and also allow Microsoft to push updates on an as-needed basis. “Bully for Microsoft!” Ed and I agreed, but most enterprises aren’t going to pick up and run with Microsoft patches without testing them outside the  production environment first, and then only rolling those that pass testing and verification out into production during carefully scheduled update windows for that purpose. I’m not sure how this is supposed to end Patch Tuesday, but Ed has commissioned me to write a 600-700 word article on this impending technology for submission later this month. I look forward to reporting further on this as I learn more. In the meantime, chew on this cool blog from System Center guru Robert Smit (a Server Cluster MVP for Microsoft) which even has screenshots of the CAUW at work: “Windows 8 Cluster Update #CAUW ( Cluster Aware Update Wizard ).” Way cool!

PowerShell 3.0 CTP Coincides with Windows 8 Developer Preview

Ed Tittel Ed Tittel Profile: Ed Tittel

Die-hard MS pre-release technology consumers already know that CTP is shorthand for “Community Technology Preview,” a pre-beta technology release stage that usually seeks to help developers become familiar with and prepare for important coming Microsoft technologies. Timed to coincide with the Developer Preview for Windows 8 (which shares a common code base with Windows Server, lest anybody forget that scripting languages are more important for servers than desktops, by and large), there’s a CTP for Windows Management Framework 3.0 now available, and it includes a reworked version 3.0 of the Windows PowerShell scripting language that offers some pretty cool new features and capabilities.

There’s a nice post to the Windows PowerShell Blog entitled “Windows Management Framework 3.0 Community Technology Preview (CTP) #1 Available for Download” that explains all this stuff in more detail, but here are some high points of what the latest iteration of PowerShell 3.0 is going to deliver:

  • Support for workflows that can “perform complex, large management tasks such as multi-machine application provisioning.” Also “Windows PowerShell workflows are repeatable, parallelizable, interruptible, and recoverable.”
  • Support for robust sessions, means that PowerShell sessions can “…automatically recover from network failures and interruptions…” and more.
  • Simplified language syntax for PowerShell 3.0  makes “…commands and scripts look a lot less like code and a lot more like natural language.”
  • Extensions to support cmdlet discovery, automatic module loading, and a new Show command that provides easy methods for users to find and use cmdlets properly

You’ll also find changes to the Windows Management Framework (aka WMI), including a new provider development model that makes it easier to build service providers, and extends management applications running on Windows outside the Windows umbrella. Likewise, remote management (WinRM) has also been extended to include more robust and resilient client sessions, for more comprehensive and robust remote management facilities. There’s even a PowerShell Web Service that offers remote access for calling cmdlets from Windows or non-Windows clients. Way cool!

Windows 8 User Profiles: Roaming in the Cloud?

Ed Tittel Ed Tittel Profile: Ed Tittel

Wow! There’s a fascinating new post on the Building Windows 8 blog from Monday (9/26/2011). It’s entitled “Signing in to Windows 88 with a Windows Live ID,” and it explains how Windows 8 users can employ a Windows Live ID as the OS log-in so they can synchronize application settings, preferences, and “environment stuff” across multiple Windows 8 machines and devices.

In a nutshell things work as explained in this bulleted list that I lifted directly from the Live ID blog I just cited:

  • Associate the most commonly used Windows settings with your user account. Saved settings are available when you sign in to your account on any Windows 8 PC. Your PC will be set up just the way you are used to!
  • Easily reacquire your Metro style apps on multiple Windows 8 PCs. The app’s settings and last-used state persist across all your Windows 8 PCs.
  • Save sign-in credentials for the different apps and websites you use and easily get back into them without having to enter credentials every time.
  • Automatically sign in to apps and services that use Windows Live ID for authentication.

The key phrase that impelled my blog title appears a little later in this post, is in a later paragraph that explains in more detail what kinds of settings are captured and preserved (“… your lock screen picture, desktop background, user tile, browser favorites and history, spell check dictionaries, Explorer settings, mouse settings, and accessibility settings, among many others…”). It says that all of these things “… are now associated with your Windows 8 account and stored in the cloud.” But alas, this capability apparently applies only to Metro style apps because the blog further states: “If you want to roam your settings for desktop apps then you can continue to use the mechanisms available for roaming profiles and client side caching of files available with Active Directory and Windows Server.”

Dang! I see the emergence of a two-tier system here, and a powerful impetus to move users onto Metro style applications. It will be VERY interesting to see how this all plays out, and to see if application developers take the bait and start building Metro style interfaces for most common and popular applications. Only time will tell, but this should be fascinating to watch and learn from.

Testing Footprint Reduction Methods for SSD Migration: Before (Part 1 of 2)

Ed Tittel Ed Tittel Profile: Ed Tittel

OK, so I’ve been blogging lately about a bunch of steps to migrate from a conventional notebook PC hard disk to an SSD replacement. I’m starting that process today on my Alienware M11x notebook, a powerful but compact Dell unit I purchased a couple of months ago. This blog post is the first of a two-part series that will cover my further learning and experience as I work through my recommended motions to see what happens, and to report on additional learning along the way, and any potential gotchas I might also happen to encounter. This posting is the “Before” part, wherein I’ll provide snapshot information about the system in question and the state of the conventional hard drive before I fire up the process to get things going. Here’s a professional photo of the system in question (which is a very sweet little notebook PC):

Side view of the Alienware/Dell M11x notebook PC

I’m going to tweet my activities and progress as I work through the migration process, and then summarize what I record to file Part 2 later this week. But for now, here’s what I see when I poke around on this system:

Hardware Summary

AlienWare M11X Hardware Summary (Before)
Item Data
BIOS Version 1.0.A02
CPU Intel i7-2617M (1.6 GHz)
RAM 2×4 GB DDR3-1333 Samsung
Video Intel 3000 Graphics processor/
Nvidia GeForce GT 540M (2 GB)
HD Seagate ST98400423AS 500GB (7200 RPM)

Hard Disk/OS Summary

AlienWare M11X Hard Disk/OS Summary (Before)
Item Data
System Drive 40.7 GB Consumed
OS Windows 7 Ultimate x64
VSS Space allocated 9.15 GB (2% reserved)
Windows folder size 14.9 GB
Windows Experience HD 5.7 (Seagate 500GB HD)

Because I’m going with a nominal 120GB SSD on this machine, I don’t actually have to reduce the drive footprint to get anything to fit. But I’m going through the motions anyway, to report on my findings and get more practice, and also to document the entire migration process along the way. Stay tuned for my next report on this on Wednesday morning.

Great UEFI Post Appears on “Building Windows 8” Blog

Ed Tittel Ed Tittel Profile: Ed Tittel

MS UEFI diagram

Microsoft’s UEFI boot sequence diagram from “Building Windows 8” blog post

The BW8 (Building Windows 8 ) blog struck gold again yesterday (9/22/2011) with a new post entitled “Protecting the pre-OS environment with UEFI,” a discussion of how the Unified Extensible Firmware Interface creates a secure boot environment for PCs modern enough to include this latest-generation collection of “…chipset, hardware, system, firmware, and operating system…” components in their makeup.

I’ve been curious about UEFI for a long time now, having read about it in numerous books, articles, and discussions of PC architecture and BIOS replacement technologies. This blog post goes a long way toward filling in the gaps in my knowledge base, and can probably do the same for you, in explaining what UEFI is, how it works, and how it helps to define a firmware validation process better known as “secure boot.” The big issue is that before the OS loads, older BIOS based systems can be hijacked by malicious boot loader programs that work outside security coverage built into an operating system or antimalware software, simply because this permits malware to take up residence in a system before any of these protective or palliative measures can be brought to bear on the security situation.

The only problem here is that motherboard makers for desktop or notebook PCs have been slow to release UEFI-based systems (MSI demo’ed an X79 motherboard with UEFI at IDF on September 19, 2011; and AMI announced its supportfor the UEFI BIOS at the recent MS BUILD conference on September 15, 2011). I don’t think we’re going to see widespread desktop/notebook support for this technology until 2012, but of course that means Windows 8 will be able to support it–but only on systems new enough to include built-in UEFI. If you ask me this strikes another interesting blow at the notion that “any system that runs Windows 7 can also run Windows 8” that MS has bruited about from time to time. Given the recent Hyper-V disclosures (which require SLAT support in the processor to run the hypervisor) and now this, it looks like that while older Windows 7 PCs may be able to run Windows 8, they will most assuredly not be able to take advantage of some of its most interesting and advanced features.

Noodling on Windows 7 Footprint Reduction for SSD Migration

Ed Tittel Ed Tittel Profile: Ed Tittel

I’m in the process of switching all my production notebook PCs over from conventional hard disks to SSDs, thanks to a recent sale at Newegg that put the latest 120 GB OCZ Agility 3 units (SATA 2/3, SandForce-based, with astonishing read/write data rates for SATA 3 in excess of 500 Mbps) for under $170 a pop. To that end, I’ve been noodling on various techniques for reducing the Windows 7 footprint to move from 250-500 GB HDs to a 120 GB SSD replacement. I’ve been blogging like crazy on this topic over at, so I’ll share some pointers and observations here, and make some recommendations for similarly-minded IT professionals and computing enthusiasts:

  • You can use a nice CodePlex tool called DriverStore Explorer to identify and delete obsolete or duplicate drivers from the Windows 7 C:\Windows\System32\DriverStore\FileRepository directory. This has never failed to deliver less than a 1 GB disk space saving on all of the systems I’ve tried it on, notebook and desktop systems alike. See my blog “Another Nice System Drive Cleanup Maneuver: DriverStore Explorer.”
  • If you’re running VMs on a PC, you can easily relocate the huge virtual hard drive (VHD) files from your system disk to a different hard disk, even a plug-in portable USB (preferably USB 3) hard disk, if your notebook supports that technology. Read more about this at “More Noodling on System Drive Space-Saving: Move those VHDs!” I have yet to save less than 4 GB on any VHD I’ve relocated, sometimes a great deal more space than that, in fact.
  • If you run Outlook without storing messages via an Exchange server, you’ll have two or more large PST files to deal with by default–namely, Outlook.pst and Archive.pst. I’ve learned some interesting tools and techniques for repair and compaction of such files, covered in my posting entitled “Interesting tips and tweaks for PST file cleanup & optimization.” Check it out: on heavily used systems these techniques usually deliver 2-4 GB of space savings!
  • Be sure also to check your restore point allocation for the system system: Click the Configure button in the Protection Settings pane on the System Protection tab of the System Properties windows (launch this by clicking Start, right-clicking Computer, then properties, then System Protection), to manage your Disk Space Usage setting. My laptops with 250 or 500 GB drives routinely allocated 10 GB or more to this use, and I trim to under 4 GB for a 120 GB SSD. More big space savings that way.
  • Download and run Piriform’s CCleaner on your notebook or PC hard disk before you do your migration process. There’s absolutely no point in copying over stuff that needn’t be on your drive in the first place. You should also grab the SourceForge software package WinDirStat and use it to zero in on large files and directories on your system to see if there’s stuff you can move or delete before imaging over the hard disk contents to an SSD. YMMV will vary on space savings realized.
  • Look over your applications carefully before you migrate, too–I use Revo Uninstaller to clean apps off of my systems–because you can save on disk space by eliminating unnecessary applications. On new PCs or laptops, I’ll often use the PC Decrapifier to get rid of pre-installed programs I don’t want or will never use from my machines. You may find it helpful, too. YMMV will vary on space savings realized here, too.

If you have any other space-saving tips for Windows 7 machines, please share them as comments on this blog post. If I get any real doozies, I’ll write them up and give you credit for inspiration, too! Thanks in advance.

The Real Secret Behind SLAT and Hyper-V for Windows 8

Ed Tittel Ed Tittel Profile: Ed Tittel

So now that I’ve been introduced to Second Level Address Translation (SLAT) as a requirement for Hyper-V on the upcoming release of Windows 8 (see my recent blog on this discovery at “Be Prepared for Windows 8 Hyper-V Gotcha“) I’ve been wondering about why it has to be this way. So I dived into the newly-created Windows 8 Developer Preview MSDN forums to see what I could learn there, and in the context of a discussion entitled “Hyper-V cannot be installed on Lenovo Thinkpad W500” I found a lovely source of enlightenment on this topic. While it is technical enough to make some eyes bleed, it does provide a key insight into the SLAT requirement.

Ben Armstrong explains how SLAT avoids Hyper-V performance bottleneck

Microsoft\’s Virtualization Guy Explains Hyper-V and SLAT

This source is Ben Armstrong’s blog from waaaaaaaaaaaay back in November 2009 entitled “Understanding High-End Video Performance Issues with Hyper-V.” In a very tight nutshell, the upshot of this posting may be summarized as follows:

1. High end graphics cards require frequent and resource-intensive/expensive memory allocations that come from using a PAGE_WRITECOMBINEprotection operation in the hypervisor.

2. This requires the kernel memory manager to flush the translation lookaside buffer and the page cache, which in turn sends an intercept into the hypervisor.

3. Lots of resource intensive hypervisor operations like this turn a (normally) infrequent operation into something frequent enough to hamper or cripple performance. There’s a great diagram in the blog post that shows why a hypervisor falls prey to this limitation, while a virtual machine manager (VMM) like that found in Virtual PC or Virtual Server remains immune to the problem. And interestingly, the faster and more capable the video card in a PC the more likely it is to fall prey to this problem.

One fix mentioned in Armstrong’s blog reads as follows “Get a system with Second Level Address Translation (SLAT).” This lets the hardware handle multiple translation lookaside buffers, on a one-per-VM basis (which is just what’s needed to sidestep the potential performance bottleneck that could otherwise occur). It looks like Microsoft simply opted to avoid potential performance problems from older hardware that might otherwise experience significant delays on the desktop to bypass potential customer complaints. In light of Armstrong’s admonitions to use the SVGA driver, choose a low-end graphics card, or turn off advanced graphics features, I find this decision “interesting” (in the sense of the Chinese curse) but also eminently understandable and defensible. But I still sigh to think of my otherwise very capable quad core Yorkfield processors (QX9650s, in fact) being consigned to the scrap heap of history (or turned into hand-me-downs) because they can’t run Windows 8 Hyper-V.
