Windows Hardware Problem Fixed: Mystery Started

Ed Tittel Ed Tittel Profile: Ed Tittel

Last February or March (2010) I purchased very nice HP notebook PC for about $1,100: it’s a dvtt-2300 CTO Entertainment Notebook PC with a Mobile i7 Quad-core processor (720QM 1.6 GHz), 6 GB RAM, nVidia GeForce GT 320M graphics, and a 7,200 RPM 500 GB hard disk.

This unit also includes a USB-attached fingerprint scanner made by Validity Sensors, Inc. model VFS301. Ever since I bought this notebook, and despite several calls to HP Support early on after I’d purchased it, the fingerprint sensor has failed to “report in” every third time I start the machine up from a sleep or hibernation state. Following resumption of activity, the notebook would inform me on those occasions that it failed to detect the fingerprint scanner, and thus, that it could not be used. Every time, that is, until I installed the latest round of Patch Tuesday updates. Then the problem went away.

At first, I thought there might have been a driver update that snuck past me for the device. Nope. The driver date is 5/4/2009. Because it’s connected via USB, I next checked to see if any USB drivers had been updated. Nix: all those drivers predate the release date for Windows 7. Sleep and hibernation fall under the control of ACPI, so I checked to see if any of those drivers had changed, either. Nada. Same 6/21/2006 date as for USB (probably associated with Windows Vista).

So why did something that was working hit-or-miss all of a sudden start working without a hitch? It’s been 10 days now since the second round of updates for April hit that machine (released 4/26, updated on 4/27 on the dv6t) and not once has the fingerprint scanner gone missing at boot-up or upon wake-up from sleep mode. As far as I can tell, the only possible culprit is Update for Windows 7 (KB2492386) another of the legion of poorly documented (read the Knowledge Base article, if you think you can read between the lines better than I can) Application Compatibility Updates that Microsoft occasionally releases.

You’re probably wondering why I bothered to dig into something that fixed a problem rather than causing one. Surely, that’s reason for rejoicing, rather than investigation? I can’t help it, I’m terminally curious about what causes changes in the behavior of my systems. I’m just as intrigued (and a little bit piqued) to have a problem fixed mysteriously as I am to have a new problem show up on one or more of my systems. If anybody else has other ideas on what might have changed the fingerprint scanner from occasional bad boy to good to go, I’d sure like to hear them. Please comment!

More Interesting IE9 Shenanigans

Ed Tittel Ed Tittel Profile: Ed Tittel

OK, so I’ve been slowly rotating my Windows 7 PCs (of which I currently have 7 at my disposal) from IE 8 to IE 9, thanks mostly to the elevation in status at Windows Update from optional, manual update to automatic or pushed update. By and large, this transition has gone reasonably well, but I do still have some gotchas with WordPress to contend with (I blog 40-plus times per month, of which only 4 or 5 posts occur outside the nearly-ubiquitous WordPress umbrella — in fact, I’m writing this very blog using WordPress right now).

This blog's WordPress page header

Page header for this blog

I’m also writing it using Chrome 11.0.696.60, because IE 9 remains unusable with this software. Why? Simply put, the cursor based button controls don’t work, and thus I can’t insert hyperlinks into my posts unless I decide to edit the HTML by hand (insert explicit <a href=”link” …> markup myself, in other words — not gonna happen: I *like* automation). So while I’m waiting for the powers that be to figure out what’s up and how to fix it, I’m using Chrome. And I must say, it’s doing its job quite nicely.

But the other day, when I applied the most recent Patch Tuesday updates to a machine that had been sitting idle for a while, I found myself in an infinite loop situation with IE 9. When you install a new IE version over an old one (this time it was going from IE 8 to IE 9), it copies the old preferences, favorites, and other settings from the old version to the new as part of the upgrade. I’m loaning out my old HP “Dragon” to a pool-playing buddy and I was updating that machine to the latest and greatest of everything. But when that process completed, and I tried to run IE 9 for the first time, something about tht install caused the browser to crash every time it tried to load the default home page for the Google search engine at www.google.com.

IE 9 tries to automatically recover when such things happen, so it closed the open (and only window), then tried to reload the Google page again, only to crash again. Repeat ad infinitum, and ad nauseum. The only way I was able to stop the madness was to jump into task manager and kill all active iexplore.exe processes.

Fixing the problem required some interesting contortions, too. I had to jump onto another machine and download a standalone browser installer for the Dragon because it had no working Web browser installed (IE 9 remained hosed, and I had just cleaned all the extraneous software off that machine for my buddy, so he could gunk it up however he chose). I couldn’t get the Chrome standalone installer to work on that machine, so I ended up using Opera instead. It let me visit the Microsoft Download Center where I grabbed a clean download for 64- and 32-bit IE 9, believing that something was wrong with the install that Windows Update left on my machine.

However, Windows detected that IE 9 was already installed on my PC, and wouldn’t let me install the older Download Center version on top of the newer but non-operational version. So I had to go into the Programs and Features widget in control panel, then use the “Turn Windows features on or off” to disable IE 9. After a reboot, I was then able to successfully install the Download Center version, and re-apply the now-missing updates from Windows Update between the release of the initial version and its current state. No more issues with loading the Google search page, and finally back to IE 9 status quo, such as it is.

My point here is that you are still likely to encounter the occasional gotcha with IE 9 in your users’ desktop environments. I have to agree with Windows mavens like Ed Bott and Paul Thurrott, both of whom still recommend that enterprises hold off on IE 9 upgrades until the program settles down a bit more, and gets additional bugs shaken out. At the very least, you’ll want to test your user runtime environments long and hard, and make sure IE 9 survives those tests gotcha-free, before inflicting the latest Internet Explorer version on your user community. Otherwise, you’ll just wind up making more work for yourself in the long run (and for your hapless help desk counterparts).

Windows 7 Migration Myths and Numbers from the Unisys Perspective

Ed Tittel Ed Tittel Profile: Ed Tittel

Unisys VP Sam Gross has been in the news quite a bit lately since he posted a blog last week (April 28, last Thursday) entitled Busting Windows 7 Migration Myths. His reports on a recent Unisys customer survey indicate that more than twice as many respondents (53%) either “haven’t started” or are “not migrating” to Windows 7, as compared to those who are currently migrating to the newest Windows desktop OS (21%). It’s not clear if that means the remaining 26% not covered in those categories have already migrated, but I suspect that’s the case as that number squares with other reports on Windows 7 migration rates in the business community.

Some analysts and commentators have taken this report as evidence of pique from Unisys — a major Microsoft partner, and one heavily involved in business computing services, including numerous high-profile, large-scale upgrades to Windows 7 — but I’m not sure that’s really what’s going on here. In this blog posting, Gross goes on to recount five myths about Windows 7 migration that he and his team have undoubtedly encountered in selling and delivering their services to the business marketplace. These not only make interesting reading, but they also point to a situation that spells increasing interest and unbridled optimism about what Windows 7 can do for enterprise networks:

  1. Businesses begin with an accurate sense of migration scope. Gross quickly debunks this myth, and recommends that organizations spend up to 3 months conducting an in-depth inventory “that includes all the hardware and software that touch the desktop.” He also recommends upgrading “high-dependency apps prio to the migration,” with “sufficient time to test applications prior to rollout.”
  2. Windows 7 fits seamlessly into current desktop architectures.  Any time a new OS hits the network, it’s necessary to “…verify compatibility, and upgrade or replace aging or outdated components…” and to “…add network capacity as needed.” I agree with his observation that desktop infrastructure always needs work when a new OS hits the network, its servers, and support and management tools involved.
  3. Windows 7 extends the life of current PCs. Maybe, but not necessarily a good idea! Extending the life of older PC hardware can increase TCO, according to Gross, and fails to enable organizations to exploit newer graphics hardware, higher RAM capacities, faster, bigger disks, and faster CPUs to boost productivity. His advice: “Be sure to build time and cost into your migration project plan to allow for hardware refreshes.”
  4. Migrating to Windows 7 automatically lowers IT costs. Sure, Windows 7 can “…improve efficiencies and cut computing costs,” as Gross observes, but that doesn’t translate into reduced IT overhead and costs unless the entire infrastructure is upgraded along with the OS, and that takes time and effort, and costs money, too. Processes and procedures often must also be tweaked (and carefully monitored) to maximise efficiency and productivity. There’s nothing automatic about any of these things: hard work, careful planning and deployment, and ongoing maintenance are all required.
  5. Windows 7 automatically reduces the management burden. The OS does not manage a desktop environment for or by itself. A migration can (and should) provide an opportunity to rethink and rebuild desktop infrastructure to make desktops more standardized and more manageable, but here again, there’s a lot of time, effort, thought, planning, and investment involved in getting things right. Nothing automatic here, either.

To those who say Gross sounds unhappy with the rate of Windows 7 adoptions, I say “bunk!” His blog, and the Unisys business plan, read a lot more like a savvy, experienced IT services company trying to cultivate more business, than a complaint against slow Windows 7 migration at the enterprise level. Trust me: It’s not a problem, it’s a real opportunity, and one that I believe Unisys wants to ride to improved financial results.

AnandTech Review Reveals Inner Workings of Windows Thin PC

Ed Tittel Ed Tittel Profile: Ed Tittel

Lots of IT professionals have been wondering about the footprint and capabilities of the Windows Thin PC product that Microsoft released for a community technology preview (CTP) in March, 2011. The stated goal of this Windows OS is to enable older and less capable PCs to enjoy and use Windows 7 core features, so that frugal organizations and companies can convert existing PCs into thin clients running a stripped down version of Windows 7.

When I’d read about this technology, I’d hoped it might mean older PCs with less than 1 GB of RAM, or older and slower single-core CPUs, might be able to tune into this Windows 7 version. Alas, Andrew Cunningham’s review “Windows Thin PC: Windows, Slimmed Down” puts paid to any such foolish notions. System requirements for Windows Thin PC are identical to those for all other Windows 7 versions (as shown in this table from his article):

“What’s the appeal for this product?” is something readers may be wondering at this point. Windows Thin PC (which I’ll abbreviate as WTPC henceforth) lets businesses use all the MS goodies they’ve got seamlessly, such as the typical combination of AD, private Windows Update servers, image creation and deployment tools, and group policy objects to define, update, manage and secure these clients the same way they handle all their other desktops. WTPC also works with the latest version of Remote Desktop, including those available on Windows Server 2008 R2 boxes running SP1. WTPC even includes a special Enhanced Write Filter that prevents end users from changing their OSes permanently, thanks to storing all such changes in a partition separate from the base Windows OS partition.

On the plus side, WTPC is supposed to become available to MS volume license customers for about $100 per copy per year. On the minus side, it will only be made available through a VPA or other similar legal scaffolding, and not through normal retail or OEM channels. Cunningham’s article also performs a detailed analysis of WTPC resource consumption, including RAM (505 MB versus 621 MB for Win7 Ultimate), disk space (2.7 GB on disk vs. 8.64 GB for Win7 Ultimate), but with no real change in base-level performance. And other than some Microsoft programs and utilities (which detect the OS and inform users that they are not compatible with WTPC) Cunningham was able to install and use a wide variety of third-party programs on a machine running WTPC as well.

What does this mean for enterprise use of WTPC? It may give older hardware a longer lifecycle thanks to an ability to run the new OS on older gear, but it reminds of Perry the Platypus on Disney’s “Phineas and Ferb” (“They don’t do much, you know…). Except in situations where there is both the need and the desire to keep using old PCs, I don’t see much business application for this technology.

Another Patch Tuesday? Round 2 for April, 2011

Ed Tittel Ed Tittel Profile: Ed Tittel

As I was poking about for a topic for today’s blog, I stumbled across Ed Bott’s ZDNet posting from yesterday entitled “The other Patch Tuesday brings crucial fixes for Windows.” I’d already noticed a login prompt when I sat down at my production PC this morning, and had wondered if MS had pushed some out-of-cycle updates out the door yesterday. Indeed, they had. What I didn’t notice (but confirmed through careful perusal of my Windows Update history over the past year) is that Bott’s observation that Microsoft seems to be getting into a twice-a-month Tuesday push on the 2nd and 4th Tuesdays of the month is right on the money. I guess that means it’s really a “Patch Tuesday Twofer regime” these days, rather than a single Patch Tuesday as Microsoft has sometimes proclaimed to be the case.

Here’s what hit my machine this morning, straight from the Windows Update history page:

7 Updates for the 2nd Patch Tuesday This Month!

7 Updates for the 2nd Patch Tuesday This Month!

Here’s more information on the items involved:

1. Microsoft Keyboard: an update to Intelli-Type showed up, along with more typical Patch Tuesday stuff.

2. KB2492386: Application Compatibility Update for XP, WinServ03, Vista, WinServ08, Win7, and WinServ08 R2

3. KB2506928: A link in an HTML file opened in Outlook doesn’t work in Win7 or WinServ08 R2

4. KB982018: Improve compatibility with Advanced Format Disks for Win7 and WinServ08 R2 (4KB sectors)

5. KB2522422: Cannot print from IE9 using some Canon printers

6. KB890830: Update to MS Windows Malicious Software Removal Tool

7. KB2515325: Windows Explorer may crash in Win7 or WinServ2008 R2

I’m not really too sure about Items 1-6 in the preceding list as to their urgency for an out-of-cycle update, but I’ve been struggling with Windows Explorer weirdness on several of my Windows 7 machines for the past 2-3 months. I sincerely hope this update will solve those problems (which also include a refusal to update the display, even with a forced View refresh, when adding or renaming files and folders in some situations) and improve my only lingering Windows 7 system issue on those PCs. I’m going to keep an eagle eye on this, and remain optimistic, and plan to report on those observations in a week or so. Number 7 in particular bears hard scrutiny and roll-out testing potential, prior to the next Patch Tuesday on May 10th, IMHO.

Microsoft Hits 350M Copies Sold for Windows 7 18 Months After GA

Ed Tittel Ed Tittel Profile: Ed Tittel

It’s not in the same league as McDonald’s Hamburgers (however many billion they’re up to by now), but it ain’t at all bad. Microsoft has sold more than 350 million copies of Windows 7 in the 18 months since its general availability (GA) date of October 22, 2009. That’s almost double what Vista sold 18 months out of the gate (180 million, according to Paul Thurrot’s recent Windows IT Pro article on this subject), and 50 million more than what the now-revered Windows XP sold when it had been out for 18 months (130 million, also according to Thurrot’s story).

This also means that Windows 7 has managed a run rate of nearly 20 million units per month (19.44 M to be more precise) since the product first shipped. A different basis for comparison in terms of percentage of PCs sold with Windows pre-installed over the same time period puts the numbers like this: 67 percent for Windows 7, 44 percent for Vista, and 54 percent for XP. Where some readers may be inclined to see this Windows 7 number as high, however, Thurrott is inclined to see it as low because he explains that it includes retail box sales or downloads for Windows 7 upgrades to existing PCs as well as for new PC sales with the OS pre-installed. Given that Windows 7 has sold lots of copies for upgrades, he’s guessing this puts the real new PC share closer to the XP number of 54 percent. Rightfully, he goes on to wonder why so many PCs are still selling with an older Windows OS installed, and guesses that makers are still selling lots of lower-powered PCs with XP installed, especially in less-developed markets outside the first world (shoot, Asus was selling netbooks with XP pre-installed until the end of 2010, and didn’t switch over to Windows 7 Starter edition until their OEM contract for XP ran out).

However you choose to slice and dice these numbers, I agree with Thurrot and others that Windows 7 is the best selling PC OS, ever. And with the end of the line for XP coming soon (no more licenses for sale as of October 22, 2010, one year after Windows 7 GA) and the life-cycle scheduled to end on April 14, 2014, I also agree with Thurrot that Windows 7 may still have its best sales in months and years ahead, before Windows 8 comes along some time in 2012 or thereabouts.

Great, Compact Windows File Search: Search Everything

Ed Tittel Ed Tittel Profile: Ed Tittel

I occasionally cover great (and mostly free) Windows software tools in this blog, in the interests of helping other Windows admins stock their handy-dandy toolkits. This weekend, I stumbled across a fabulous little (334 KB download, 539 KB installed) free file and folder search tool named Search Everything. Here’s a snap from its download page that tells most of the story quite nicely:

Voidtools.com is where you'll find Everything

Voidtools.com is where you will find Everything

Even though I’m running on a reasonably fast Windows system (Intel QX9650 CPU overclocked to 3.5 GHz, Intel 80GB SSD) Explorer is still a little laggy on that machine, especially when I fire off the built-in search facility. Everything beats the pants off Explorer on a series of simple sample searches by a margin of almost 2 to 1 (which is to say it’s nearly twice as fast). That said, it does search only file and folder names, not file contents. But in most cases, it finishes the search before or exactly as you type your search string, whereas Explorer can take a few seconds, particularly when pointed at non-indexed drives. Definitely worth a spot in your tool collection!

Everything searches all 4 of my drives for "cim" in under 1 second

IE 9 Poses Some “Interesting” Problems

Ed Tittel Ed Tittel Profile: Ed Tittel

I’ve switched over from IE8 to IE9 on about half of my Windows 7 PCs, including two desktops and one of my laptops. So far, things have been going reasonably smoothly in the two weeks or so I’ve been using this new browser, but I have encountered one set of “interesting” problems (in the sense of the famous Chinese curse “May you live in interesting times”). Curiously enough, these have to do with the very program in which I’m creating this blog post — namely, WordPress. In fact, I’m posting my blogs using Chrome these days because while the site operators know that IE9 is having problems, they haven’t yet figure out how to fix them.

Let me recount my current difficulties:

  • I can’t access any of the toolbar elements at the head of the primary posting window (as shown in the following screen snippet). This is the usual method for controlling text, using bulleted or numbered lists, managing text alignment — and entering hyperlinks to attach to other Web pages. I can click on the icons and see them highlight to indicate they have been selected, but for some reson the associated actions that usually go with them don’t fire off and do their respective things.
I click the icons but nothing happens

I click the icons but nothing happens

  • When I try to upload a graphic to illustrate my blog, I can launch the Explorer based download widget, access the file navigation and selection window, but when I click the Upload button, the widget display area goes all white, and essentially freezes in that state without every uploading anything.
Alas, these two sets of problems are more than sufficient to keep me from writing and posting my blogs using IE9. I’ve communicated my issues to the site operators, and they’ve dispatched some programmers to look into and try to solve these problems, but it’s been a week and so far there’s no word as yet even with an ETA as to when things might be fixed. Until then, I have no choice but to use an alternate browser for the ten or more blogs I routinely write every week.
This leads me to recommend to my enterprise admin readers that they test Web-based applications and UIs carefully with IE9 before rolling the new browser out. This goes double for any custom or home-grown Web apps, many of which tend to be seriously sensitive to browser eccentricities and idiosyncrasies. Looks like some  period of “bug shakeout” (or being more charitable, “change adjustment”) will be necessary before IE9 can take up a predictable spot on enterprise desktops around the corporate world!

Patch Tuesday: April 2011 Is a Doozy!

Ed Tittel Ed Tittel Profile: Ed Tittel

Here’s what I found waiting for me on my production Windows 7 Professional (x86) machine this morning, in the wake of the latest Patch Tuesday:

Up to 24 files to download and install!

A personal record for Patch Tuesday: Up to 24 files to download and install!

Notice that only two items are unchecked by default: KB2511250 relates to an issue printing SVG graphics or CSS3 style sheets in IE9, and the Malicious Software Removal Tool is a usual Patch Tuesday feature. The former is something many users are not likely to need, while Microsoft is being smart about leaving the latter unchecked because it takes some time to run to completion and has occasionally caused problems when batched in with Patch Tuesday stuff in the past.

What’s in a number? Windows 7 Market Share Stats…

Ed Tittel Ed Tittel Profile: Ed Tittel

OK, so I’ve been watching Windows 7 market share numbers climb steadily month after month, ever since its general availability date in October 2009. Here’s what the latest marketshare distribution looks like for March 2011, according to NetMarketShare.com:

Windows 7 market share

But as the saying that Mark Twain popularized in 1906 as “There are three kinds of lies: lies, damned lies, and statistics” would have it, numbers can be diced and sliced in an infinite variety of ways. That’s why I read the following ComputerWorld headline this morning with great interest and eventual bemusement “Windows 7 share tops XP for first time in US.”

Here’s one line from that story that says it all, with tongue-in-cheek homage to the “three kinds of lies” epigram: “In the first 10 days of April, Windows 7’s average daily share was 32.2% as measured by StatCounter, besting XP’s average of 30.7%.” Later on in the same story ComputerWorld fesses up to relate: “Data from rival metrics vendor Net Applications paints a less-impressive [Ed remark: and more consistent with NetMarketShare.com] pciture for Windows 7. Net Application’s March numbers put Windows 7’s global usage share at 24.2%, compared to XP’s 54.4%.

The key issue here, of course, is the source of the numbers involved. The graph at the head of this blog comes from all over the world, and StatCounter’s report is focused purely on the United States market.  StatCounter’s explanation for the difference, as relayed in the CW story is: “Because China accounts for a major chunk of all computer users and because a higher percentage of Chinese users run Windows XP than those in virtually every other country, Net Applications’ XP numbers are higher than StatCounter’s.” And you can’t get NetMarketShare (or its parent company, NetApplications) to disclose market share data by country without a for-a-fee “geolocation upgrade.”

But this contrasting graph from StatCounter, which clearly shows the crossover point between Windows XP and Windows 7 in the US occurring in early April (dark blue and light yellow lines), does give some credence to StatCounter’s reporting. But without independent and reliable confirmation, I can only treat this report as suggestive, rather than conclusive. Even so, Microsoft should be taking great cheer from these numbers, while also hoping that the Chinese legions get on the upgrade bus before the end-of-life date for XP in 2014.
