Fixing Non-responsive Taskbar Icons

Leave a comment

Last December, I wrote an article here that described an easy fix for an unresponsive Start Menu. The trick on my affected PCs was to go into Task Manager, right-click Windows Explorer, and select “Restart.” Over the past week the same thing is affecting Task Bar icons for open and pinned applications. It came in the wake of the occasionally wonky preview version of the upcoming March CU. That is, I’m inclined to name KB4601382 as an “update of interest” in this case. Fortunately, the same fix works.

Fixing Non-responsive Taskbar Icons

How can you tell when this problem manifests? Easy! You click on an icon in the taskbar and nothing happens. I show a portion of my taskbar icons in the lead-in graphic, by way of illustration.

I actually show the taskbar at the foot of both of my monitors. Sometimes, when one quits working, the other keeps going. Then I click that one instead. If neither works, the fix goes in. I’ve never had it fail.

As with my earlier report of Start Menu issues, I’m inclined to see some interaction between Stardock Software’s Start10 and the Explorer-based start menu and associated UI elements. Those include the taskbar icons and the notification area as well. Something wonky is happening, but is also easily fixed. I’ve reported this to Stardock and MS and am hopeful that, as before, a fix trickles into one or the other of those environments.

Seems Like a Limited Issue

I don’t see other reports of this phenomenon in the Start10 forums at Stardock. There’s plenty of discussion on the general phenomenon (Google search: “taskbar icons nonresponsive”). But all are unanimous in what to do: Restart Windows Explorer. Not much other cussin’ and discussin’ involved. Nice to know I’ve got the right fix, even if I don’t know the cause unequivocally and unambiguously. Sigh.

KB4577586 Flash Killer Download Available

Leave a comment

For those Windows 10 users with Adobe Flash still installed, the Microsoft Update Catalog has the KB457786 Flash Killer download available. If this means you, click the preceding link. Next, pick the version that matches your current Windows install. Then, click its Download button for the corresponding Microsoft Standalone Updater (MSU) file. The individual download window for the x64 version appears in this story’s lead graphic.

Note: For whatever odd reason, I had to right-click the download link in the window shown above. Upon selecting the file link near the bottom of that window, I had to right-click and select “Open link in new window” to actually get the file to download. YMMV.

If KB4577586 Flash Killer Download Available, Then What?

Once downloaded to your PC, run the MSU file that you just grabbed. The Windows Update Standalone Installer will ask you if you want to install the KB4577586 update. Click the “Yes” button to proceed.

Next you’ll see an “… updates are being installed” window appear, with progress bar. It took about 15 seconds to install on my i7 Skylake (i7-6700, 32GB RAM, 512 GB Samsung 950 SSD) PC.

If Install Fails, No Worries

I already knew that the Flash Player was gone, gone, gone from this PC. And sure enough, a peek into Update History under the Other Updates heading shows the following info:

A quick search on the 0x8024001e error string shows the most likely cause — in this case, for sure — is a missing DLL file associated with the Adobe Flash Player. Why is it missing? Because it’s already been uninstalled on this PC. Thus, there’s no cause for concern about this error. In fact, even if you don’t need this update it’s safe to run it anyway.

Those who already know Adobe Flash Player is absent on their PCs need not download or run this update. But if you’re not sure, it’s OK to do so just to make sure it’s gone. Your call!

Le roi est mort, vive le roi!

The foregoing phrase translates as “The king is dead, long live the king!” Seems like an appropriate epithet for Adobe Flash Player which has been around since FutureWave SmartSketch made its debut in 1993. Acquired by Macromedia in 1996, in turn by Adobe in 2005, Flash has been around since the earliest days of the WWW.

Now, of course, more modern technologies built into HTML 5 have made Flash obsolete. It’s now passed its End-of-Life date as of 12/31/2020. As of February 2021, all major browsers now block Flash and have no player capability. It really is over. Amazing! Many thought it would never die, and few are sorry to see it go…

Mild Microsoft Update Health Tools Mystery

Leave a comment

An interesting item is bubbling up in user forums  lately. Lots of Windows 10 PCs — including some of mine — have seen a new-ish, intriguingly named application show up. This story’s lead-in graphic shows it in second place. In fact, I’d say we’re facing a mild Microsoft Update Health Tools mystery. Typical questions include “What is it for?” and “When is it used?”

Cracking a Mild Microsoft Update Health Tools Mystery

A Microsoft Docs “Questions” item links the utility with update KB4023057 .  A corresponding support page mentions all Windows 10 versions, including 20H2. (It’s dated October 2020.) I’ve seen posts at answers.microsoft.com as far back as August 2020. It, too, references that same KB article.

That article says the update delivers “reliability improvements to Windows Update Service components.” It also says it:

includes files and resources that address issues that affect update processes in Windows 10 that may prevent important Windows updates from being installed. These improvements help make sure that updates are installed seamlessly on your device, and they help improve the reliability and security of devices that are running Windows 10.

Some Interesting Notes about KB4023057

There are 5 bulleted items (and a sub-note) the Support Note. All make fascinating reading. I reproduce them verbatim. (For brevity, I prune “This update may” or “This update will” ):

  • …  request your device to stay awake longer to enable installation of updates.

    Note The installation will respect any user-configured sleep configurations and also your “active hours” when you use your device the most.

  • … try to reset network settings if problems are detected, and it will clean up registry keys that may be preventing updates from being installed successfully.
  • … repair disabled or corrupted Windows operating system components that determine the applicability of updates to your version of Windows 10.
  • … compress files in your user profile directory to help free up enough disk space to install important updates.
  • … reset the Windows Update database to repair the problems that could prevent updates from installing successfully. Therefore, you may see that your Windows Update history was cleared.

Invitation to Conspiracy Thinking?

Go back, and read the forum traffic. Or, search Google for “Microsoft Update Health Utility.” Sadly, it reveals suspicion among community members. Indeed, some fear it helps MS forcibly update older Windows installs. In fact, MS does this already. Others don’t trust MS update orchestration. They’d rather control updates themselves. Still others worry about unwanted side effects or unusable PCs after forced updates.

Gosh! While these things are possible, I see nothing untoward at work here . Instead, I see MS staging repair tools in advance for update issues on Windows 10 PCs should they manifest. Aside from lacking user controls, I see them no differently than built-in update troubleshooters. In fact, I’m a devoted user of Shawn Brink’s Reset Windows Update tutorial and its accompanying batch file. It’s gotten me past 95% of all WU problems I’ve seen. That’s why I’ll gladly keep using it.

No Cause for Alarm

As far as I can tell, there’s not much to see here. Admittedly, Update Health Tools is a small surprise. But its Support Note offers good explanations. Thus, I’m OK with this tool. Nor should you worry, either. Rather, it looks like good software engineering.

Better yet, the Update Health Tools can handle update issues on their own, sans user input or guidance. That sounds like a blessing, even if in disguise. And FWIW, it’s missing  from Insider Preview releases. That tells me it aims squarely at production PCs outside IT umbrellas. That means mostly home and small business users. Thus, it should benefit those who need it most.

I’m coming out in favor of the Update Health Tools. I hope we’ll learn more about them from Microsoft soon. In the meantime, if you don’t like the tool, you can choose to uninstall it. I’m leaving it alone myself. If I’m right about it, it may come in handy someday.

Post Dev Channel Upgrade Drill

Leave a comment

As somebody who’s been in the Insider Program for Windows 10 since October, 2014, I’ve been through hundreds of Insider Preview installations and upgrades. That means I have a pretty well-defined drill through which I take my test PCs once an upgrade is in place. In today’s item, I’ll take you through my Post Dev Channel Upgrade drill as an illustration. That’s because I just finished upgrading to Build 21318.1000, released Friday February 19.

High-level View: Post Dev Channel Upgrade Drill

Viewed at a high level, those post Dev Channel upgrade steps might be described as follows:

    1. Check the environment, restore tweaks, make repairs
    2. Clean up post-upgrade leftovers, esp. Windows.old
    3. Perform other routine cleanups
    4. Check for and install software updates (non-Windows)
    5. Use Macrium Reflect to make a pristine image backup

In general, the idea is to make sure things are working, clean up anything left behind, catch apps and applications up with Windows, and make a snapshot to restore as this release baseline, if needed.

Step 1: Check & Restore or Repair Anything Out of Whack

YMMV tremendously during this activity. After many upgrades, I’ve jumped into File Explorer Options (Control Panel) to make file extensions visible again, show hidden files, and so forth. MS is doing a better job with this lately, and I don’t usually have to do this with Insider Preview upgrades (though it does still happen for standard feature upgrades).

For a long, long time I had to go into Advanced File Sharing to loosen “Guest or Public” and “All Network” network profiles on the Lenovo X220 Tablet to get RDP to work. Because I use RDP from my production desktop to access and work on my arsenal of test PCs, this is pretty important — to me, anyway. The last few Dev Channel releases have NOT had this problem, I’m happy to say.

I run Helmut Buhler’s excellent 8 Gadget Pack on my Windows 10 PCs. That’s because its CPU Usage and Network Meter gadgets provide helpful dashboards. The former is good for CPU and memory usage and system temps; the latter is great at showing network activity and base addressing info. Very handy. But each time an upgrade is installed, Windows 10 boots it off the desktop. Buhler has written a handy “Repair” utility that I run after each upgrade to put everything back the way it was.

Step 2: Clean up post-upgrade leftovers

You can use the built-in Disk Cleanup utility, run as admin, to take care of most of this. I personally prefer Albacore/TheBookIsClosed’s Managed Disk Cleanup (available free from GitHub). Why? Because he tweaked the UI so you can see all active controls in a single display window, and select all the stuff you want gone in a single pass. Here’s what that looks like to make it visually obvious why I prefer this tool:

Post Dev Channel Upgrade Drill.mdiskclean.exe

Notice you can see ALL options eligible for selective clean-up in a single display area in Managed Disk Cleanup. I like it!

Step 3: Perform other routine cleanups

I still use Josh Cell’s Uncleaner utility to clean up temp files and other leftovers after an upgrade. If I’m feeling ambitious I’ll run the DriverStore Explorer (RAPR.exe) to identify and remove duplicate device drivers, too. Once upon a time I would run Piriform’s CCleaner as well, but I’m less than happy with that software now that the maker has started including bundleware in the installer. I haven’t found another tool I like as much as the old version.

Step 4: Update Third-Party Software

You can use a tool like KC Softwares SuMO or Patch My PC Updater to suss out most of the items in need of update on Windows PCs. SuMO is a little better at its job but costs about US$35 for the PRO version (does automatic updates for most programs, but sometimes vexing to use). PMP Updater is free, fast, and entirely automatic but doesn’t update everything. Sigh. I use PMP Update on my test machines, and SuMO PRO on my production PC myself. I’m doing this on the theory that it’s best to have everything updated before making a pristine image backup, as I do in the next step.

Step 5: Make a Pristine Backup

With everything upgraded and updated, and all the dross cleaned up, it’s the perfect time to make a fresh image backup. I like Macrium Reflect, mostly because it’s faster and more reliable than the built-in Windows 7 Backup and Restore utility (which MS itself has recommended against since 2016). And indeed, it’s faster at backing up and restoring than most other utilities I’ve used, and also includes a bootable rescue flash drive utility you can use for bare metal and “dead boot/system” drive repair/restore scenarios.

Please note: Macrium Reflect is MUCH faster than using the rollback utility to return to a lower-level OS image from a higher-level one. That’s why I feel safe getting rid of the Windows.old folder as part of my cleanup efforts. I know I’m not going to use those files anyway…

OK then, that’s my drill. I’m sticking to it. Hopefully, you’ll find something in there to like for yourself. Cheers!

Samsung Network Printer Goes Missing

Leave a comment

OK, I admit it. I hadn’t set up DHCP reservations on my LAN. I could try to blame the Spectrum-supplied router that provides DHCP, but it’s really my fault. Thus, when I saw my Samsung ML-2581ND laser printer was offline yesterday morning, I immediately knew what was up. Generally, when the Samsung Network Printer goes missing on my LAN it’s because DHCP has assigned it a different IP address.

Look at the lead-in graphic for this story. There you’ll see that the device (Samsung ML-2850) is associated to Private IP 192.168.1.126. It had previously been …127. And as soon as I changed that address selection on the Ports tab of Printer Properties, it started working again. So how did I figure out which port it had actually been assigned?

When Samsung Network Printer Goes Missing, Then What?

That’s when I call on one of Nir Sofer’s handy network utilities — namely NetBScanner. It quickly scans the local cable segment on its address range. In fact, the program is smart enough to figure that out on its own, after which it supplies a short list of all occupied addresses in that range. Here’s what I saw when I scanned my local wired Ethernet:

Samsung Network Printer Goes Missing.NetBscan-results

Notice the entry for …126 which also shows the device name SAMSUNGNWP. That’s what I want!

It turns out I already had defined this address in the Ports tab, so all I had to do was switch the device from the now-incorrect …127 entry to the current …126 entry and it was done. That meant unchecking the box next to the former, and checking the box next to the latter. Dead simple, quick and easy to fix. As long as you know how, that is…

The Right Fix is a DHCP Reservation

DHCP lets admins make static address assignments from the IP address pool it manages. That way, devices like servers and printers can keep the same address forever, and DHCP won’t move those assignments around, as it otherwise might. That shows up under the Advanced and DHCP tabs on my Askey RAC2V1K boundary device. I reserved the …126 address for the Samsung ML-2850 and also the …15 address for my Dell Color Laser CB745E. The latter is shown here:

Samsung Network Printer Goes Missing.DellCPres

By supplying the MAC address and the desired (reserved) IP address, you tell DHCP “hands off” for future assignments.

So now, I’ve done what I should have done long ago, thanks to sharing my (prior) shame with you, dear readers. Live and learn!

SetupDiag.exe Unveils Upgrade Gotchas

Leave a comment

If you read this blog, you already know I finally got my Lenovo X380 Yoga upgraded to 21313 earlier this week. I’d been fighting a bugcheck error for the two prior Dev Channel upgrades before that. Along the way, I found myself  looking for diagnositic info about the failed upgrade.  A Microsoft tool SetupDiag.exe unveils upgrade gotchas, so I started using it. With this post, I want to shed more light on this nice little tool, based on recent experience.

How SetupDiag.exe Unveils Upgrade Gotchas

The program is a log analysis tool that focuses on Windows Setup log files. As the MS Docs page for SetupDiag says:

It attempts to parse these log files to determine the root cause of a failure to update or upgrade the computer to Windows 10. SetupDiag can be run on the computer that failed to update, or you can export logs from the computer to another location and run SetupDiag in offline mode.

That latter offline capability is nice, because it means you can boot an otherwise unbootable machine using rescue media. Once booted, you can then suck the files you need from the problem PC and analyze them on a working machine instead.

Note 1: consider bookmarking the already-quoted MS Docs page. It includes an always-current download link to the latest SetupDiag.exe version. (V160 is current as of Feb 17, 2021 only.)

Note 2: SetupDiag.exe requires .NET Framework 4.6 (or newer). See this WindowsCentral story for multiple .NETversion check methods  in PowerShell (3) or Cmd.exe (1).

Working with SetupDiag.exe

Starting with Windows 10 2004, SetupDiag.exe is included with Windows Setup on Windows 10 ISOs and other install images. Paraphrasing the MS Docs item, it says:

During the upgrade process, Windows Setup extracts its sources files to a directory named %SystemDrive%$Windows.~bt\Sources . With Windows 10, version 2004 and later, setupdiag.exe is also installed to this directory. If there is an issue with the upgrade, SetupDiag will automatically run to determine the cause of the failure.

Thus, so long as you don’t clean up after an attempted upgrade, you’ll find SetupDiag.exe in the afore-cited directory. Grab a copy and put it somewhere else, if you’d like.

Simply search your PC for SetupDiag.exe. Once found, you can run the program from Explorer, in PowerShell, at the Command Prompt, or via the run command.

Reading the Results

SetupDiag.exe writes its results in a file named SetupDiagResults.log. By default, it appeared in my download folder
(C:\Users\<uname>\Downloads).
I found it easily, because I use Voidtools Everything to locate files on my behalf. It’s how I got the details on my bugcheck error code. It reads 0X0000000A therein, but may appear as 0XA in discussions online. When I got the GSOD the error identified itself in the report window as IRQ_NOT_LESS_OR_EQUAL…

The lead-in graphic for this story shows the log file. The area of interest starts mid-way down in a line that reads: “Found crash information in rollback log.” That’s where the bugcheck code appears. Also, “nt” appears as the responsible driver. This, alas, is a built-in OS driver. Mere users cannot uninstall or update it. (That’s a Microsoft internal thing dontcha know?) It’s what convinced me that waiting for an upgrade from MS was the ultimate (and only) fix avaialble.

DISM Trumps SFC To Fix Hung Execution

Leave a comment

Here’s an interesting observation straight from TenForums. Occasionally, the System File Checker (SFC) will hang when run. That is, it will grind forward to some percentage of completion, and then sit there indefinitely, making no further progress. If that happens to you on a Windows 10 PC, it’s OK to terminate the process (enter Ctrl-C at the command line or in PowerShell). In such cases, DISM trumps SFC to fix hung execution. Let me explain…

How DISM Trumps SFC to Fix Hung Execution

To unpack my assertion, please understand that when SFC finds an error it cannot fix, it more or less stops where it is. The Deployment Image Servicing and Management tool, aka DISM, can replace the files in Winodws 10’s cross-linked code repository WinSxS. By doing so, it will often fix the errors that SFC cannot surmount successfully.

The syntax for the specific DISM incantation is most often:

DISM /online /cleanup-image /restorehealth

Other variations for offline images, or that use something other than local files already known to Windows 10 are documented at MS Docs. There you’ll find a helpful article entitled “Repair a Windows Image” that take you through various elaborations that may sometimes prove necessary. Using the Source: attribute can get particularly interesting, especially if you’re working from a WIM or ESD file that is home to two or more Windows images.

If SFC Hangs, DISM /RestoreHealth Often Sets Things Right

As it did for the person who posted about SFC difficulties at TenForums, this approach will often (but not always) make things right. You can’t know until you try. But the thing to remember is that if SFC hangs or fails, your next step should be to try this specific DISM command.

In my personal experience, this has fixed half or more of such issues when they’ve come up. If the odds come up as they should, this approach will also work for you. Try it, and see!

[Note Added Feb 16 afternoon]:
Go Ahead: Skip SFC, Run DISM First

Members of the Insider Team responding to this post informed me that “On Win10 it’s recommended to run DISM first.” This is explained in an MS Support Note entitled “Use the System File Checker tool to repair missing or corrupted system files.” And sure enough, in reading over that article it informs readers “If you are running Windows 10 … first run the inbox Deployment Image Servicing and Management (DISM) tool prior to running the System File Checker.” I’m not sure what “inbox” means in this context, but the order is clear and unmistakable: DISM first, SFC second.

I’ve been following typical advice from TenForums and conventional wisdom for so long, I neglected to read up on SFC in putting this story together. Live and learn: now I know to reverse the order and run DISM first. Hope this helps others, too!

Untangling Cascading Troubles Gets Frustrating

Leave a comment

I’ve been trying to untangle a weird mix of networking and telephony issues going on three days now. As I write this item, in fact, I’m texting with a Verizon tech support person. He’s trying to unsnarl a mix-up around a new 5G MiFi hotspot  I purchased recently. When the device was set up, it was mistakenly tied to my son’s cellphone number. Then, the tech support people tried to switch things around. Alas, they exceeded the allowable number of reset attempts. This requires a 24 hour wait before a retry is allowed. The 24 hours are up, and I’m trying again. Does this explain why untangling cascading troubles gets frustrating?

How Untangling Cascading Troubles Gets Frustrating

Let me count the ways.

  1. Verizon Tech Coaches can’t call my cellphone. It doesn’t ring because of a setting that’s available only in iOS 13 or higher. My iPhone is running 12.5. So I had to work through amazing contortions to get them to call my landline.
  2. The MiFi device hadn’t been working properly. Thus, I wasn’t able to activate it myself. First I learned how to pop the back off the device. Then, I did the old “paper clip in the recessed reset switch” routine to return it to factory settings. After that the UI worked just fine.
  3. As an iOS guy I found myself messing with Gregory’s Android OnePlus 7 Pro. This had me remembering and relearning all kinds of interesting stuff. I’m now more familiar with its UI, device settings and config data . I also now remember what’s up with ICCID and IMEI identifiers.
  4. When my tech support person tried to reset the accounts properly, the provisioning software let him make the changes, then came back and told him “transaction disallowed.” He’s now roping higher level support team members in to reset database rules to make this happen.
  5. The way I got into this snafu to begin with is that my Spectrum Internet connection won’t pass Remote Desktop Protocol through its firewall. When I attempted the necessary port forwarding operations, the device proved unable or unwilling to read the external (WAN or rather cable side) IP address, even though I can see it just fine (and Ping it) from my LAN PC. That led me to say “I can use my MiFi 5G hotspot instead” and started me down the rabbit hole.

So here we are solving problems we didn’t know we had, and dealing with mixups based on pure human frailty.

Tech Support Needs Unified Communications, Badly!

The most amazing thing I’ve learned is that at least two separate tech support operations at Verizon are inappropriately silo’ed. Their Tech Coach operation cannot place voice calls. They are restricted to online chat only. I made the mistake of initiating contact with them on my cellphone, and they couldn’t easily switch over to a PC session, either. I did figure out how to make that happen later on, though so online via cell and via PC do have some integration.

But their app is limited to calling only registered Verizon devices. So when I tried to have them call my cell early on for a voice session, I found myself in a Catch-22. I wanted them to call me, they called me, but my only acceptable target device wouldn’t allow that call to ring in (that’s the iOS setting for version 13 and up, which is turned on and immutable for 12 and under versions and so can’t be accessed or changed on my aging iPhone 6).

At this point it’s taken me over 7 hours to solve a set of problems that are only tangential to the real problem I want to solve with accessing a public IP using Remote Desktop. I’ll get to that and another series of tech support calls with Spectrum next week.

Take a Deep Breath, and Keep Waiting

But I’m learning how to keep calm and carry on in the face of massive frustration. I suppose I should be glad that I’m not the human responsible for the error that triggered this cascade. Lord knows I have been the guilty party often enough myself to write about it regularly in this very blog!

But Wait: There’s More

Yesterday when I wanted to blog about this situation, my ISP’s behind-the-scenes MySQL WordPress server went down. Thus, I was unable to access or post anything until that got fixed. The error cascade is apparently catching, so perhaps you shouldn’t have read this far. Brace yourself!

Remembering Santayana’s Dictum Win10-Wise

Leave a comment

I learned this one as “Those who fail to learn from history are doomed to repeat it.” Turns out that upon checking Santayana’s aphorism, it’s actually “Those who don’t know history are destined to repeat it.”  But when it comes to remembering Santayana’s dictum Win10-wise, I was forced to re-learn an important lesson today. Let me explain…

What Remembering Santayana’s Dictum Win10-Wise Means

A funny thing happened to me today: I installed KB4598291 but it didn’t show up in Update History nor in its Control Panel counterpart under Programs and Feaures. Why was this? Because I’d wandered off the update track to force my test PC ahead to 19043.XXX builds using a series of linked DISM statements. Sigh.

Today, I learned why that’s a BAD IDEA. When I realized that something was amiss, I learned that things were further out of whack than I’d dreamed possible. The hack meant that I could no longer use the tried-and-true “in-place upgrade repair install” technique to return my test PC to some semblance of normality.

That Key Doesn’t Work. Try Another…

I used UUPdump.ml to build a customized install ISO for 19042.789. But when I tried to run same on my “unofficial” 19043.782 machine, the installer asked for a Windows 10 key before it would proceed. None of the following worked:

  1. The generic Windows 10 Pro key
  2. The actual key for the current install, as elicited by Showkey Plus
  3. A still active MAK key for Windows 10 Pro I purchased from Crayon, Inc. in 2018

Ouch! I was in trouble. Fortunately, i was able to restore a backup from a time when this test PC was still on the regular Beta/Release Preview build track. Once I’d done that, I was able to catch up and bring the PC up to build 19042.789, as shown in the lead-in graphic for this story.

The Moral of the Story

I’d been warned by friends and colleagues that wandering off the usual Insider Preview track is OK for experiments, but not for ongoing use. Now I know why: once you hit the next Cumulative Update (as I did today) the off-track releases will get weird in a hurry. My advice: learn from my mistake, and don’t go there, unless it’s on a throwaway VM. I now understand that’s how I should have played that, too. Live and learn!

X380 Yoga 21301 Installation Issues

Leave a comment

I’ve been struggling since last Thursday to get the latest Fast Ring version — namely, 21301.1000 — installed.  That’s right, I’ve got “interesting” X380 Yoga 21301 installation issues running hot and cold right now. So far I’ve seen at least 4 different error codes, all of which hit at about the 48% mark after the first reboot. I call this the “post-GUI” phase of Windows 10 installation, because it occurs after the WinPE environment takes over the install process following that first reboot.

Diagnosing X380 Yoga 21301 Installation Issues

I’ve just confirmed that these issues persist in the latest CU 21301.1010,  as well as in 21301.1000. I’ve been using the MS tool setupdiag.exe to get to the bottom of things. But because it finds the NT driver as the culprit for the IRQL_NOT_LESS_OR_
EQUAL and the bugcheck 0X0A error, that puts the onus on MS to fix something beyond my control. You can see this in the setupdiag output in the lead-in graphic for this story.

I can tackle and fix lots of Windows 10 drivers. But as I understand it when the NT driver (shows up as lowercase nt in the screencap) is mentioned, it’s general indicator. According to dbgtech.net, “the error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version.”

Coming Up Dry Is No Fun at All

I’m running Defender on this PC so I’m pretty sure it’s not involved. I’ve stripped my services down to the bare minimum. Macrium Reflect is my backup too (and still working on the X220 Tablet that has managed both of these recent updates/upgrades). The same device drivers work on 19042.746 on my other nearly-identical X380 Yoga PC (only difference: Toshiba SSD vs. Samsung).

I’m still looking for enlightenment, but not finding any. Last time something like this happened, I just had to wait for a new Fast Ring/Dev Channel release, and it installed just fine. Here’s hoping!

[Note Added Feb 12] 21313 Brings Success!

I’d been contacted by a member of the Windows Insiders team as a result of sharing a link to this post on the Windows Insider MVP Yammer community. I was informed that a future Dev Channel release would fix my problem. As I learned earlier this afternoon, 21313 installed without difficulties. Seems that this PC got bit by a known bugcheck error.  It’s the first item on the Fixes list in the 21313 release notes. This has been a known issue for some time, and is apparently now fixed. Woo hoo!
