For the past 5 weeks or so, I’ve been working with the Lenovo ThinkPad T14s Gen5 laptop. For the last two weeks, updates have been stuck, with an error code that indicates file download issues. The usual repair techniques haven’t helped, either — namely run the troubleshooter or the reset & re-register Windows Update components. So this morning, with a new cumulative update out, I installed the latest Windows 11 24H2 repair version. That built-in repair install unsticks WU and catches me up with pending stuff, as you can see in the lead-in graphic.

Repair Install Unsticks WU Trades Time vs. Convenience

The problems with the afore-mentioned techiques (troubleshooter, reset&re-register) is that they take multiple steps and a bit of effort. Double that when, as often happens, remediation is also needed. It took a while to click Start > System > Recovery > Reinstall now and then work through that process. But the details took care of themselves and I didn’t have to do anything except fire it off to make it work.

In the end, this turned out to be easier and less vexing than the other techniques. Its results were also immediately apparent, and entirely positive, once completed — as you can see in the lead-in graphic. That said, Update History does become a little opaque when you conduct this repair. Here’s what it says now:

It doesn’t show the problem CU installed and running. It simply shows that “Windows 11, 24H2 (repair version)” got installed today. Of course, that means the installer used the latest version of the Windows image — including those problem CUs — as the install base. So really, it’s all fixed now. You just have to know what this reference means.

And ain’t that just the way things go here in Windows-World? The problem may be solved, but a hint of mystery — or is it confusion? — remains. Cheers!

Note Added 4 Hrs Later: Get-Hotfix Tells the Story

Reading through ElevenForum.com threads just now, I learned that running Get-Hotfix in PowerShell will shows installed KBs from a repair install image, to wit: This shows that various updates and security updates are indeed present in the newly repaired image. The current build number for that PC — 26100.3775 — also shows that KB5055523 has been applied. Good stuff…

Last Thursday, I downloaded and installed a new Preview CU for Windows 10 — namely KB55053634. After lunch Friday, I finally got around to rebooting to complete that process. Eventually, it succeeded. But first, just to make things incredibly exciting KB5053634 kills mouse, keyboard — my vital USB peripherals — dead. Here’s the story of what I had to do to bring those devices back to life, and actually log in to Windows 10.

KB5053643 Kills Mouse, Keyboard: Now What?

Because I couldn’t get past the lock screen without a valid input device, that turned out to be a little more vexing than one might guess. So first, of course, I rebooted again. Still no joy: the keyboard didn’t respond to keypresses (a good test on my Comfort Curve 4000 is to toggle the Function Lock or Scroll Lock keys because those also toggle handy little green indicator LEDs). Nor did a mouse click open the PIN input box as usual.

So I tried again. Still no dice. Then I thought: “maybe the device needs a cold, hard boot?” That means powering off the PSU, waiting 1-2 minutes, powering back up, and pressing the power button. And indeed, that did the trick. Once I went through that maneuver, the hardware got completely reset, reinitialized and enumerated. It was enough to restore my key USB peripherals to working order.

What (Would Have Been) Next?

If the cold boot or hard boot didn’t work, I’d have had to jump into UEFI, turn off Secure Boot, and then target bootable repair media to get something running on that PC. I’ve done it many times before and will no doubt do it again. But hey: I was glad not to have to do it this time. Cold, hard boot did the trick.

Makes me feel like I dodged a bullet. Remember to give that a try if you find yourself bereft of mouse and/or keyboard after installing a Windows update or upgrade. If you’re lucky like I was, that will bring the USB drivers back into play, and let your PC get back to work. Cheers!

Whoa! In the realm of Windows Insider Preview upgrades, sometimes you win and sometimes you lose. This time around — starting from Build 27783 — I found myself on a long, hard 27788 upgrade road for this latest Canary Channel version. When I tell you what happened, and how I surmounted the obstacles on that path, you may be able to save yourself some unnecessary time and effort.

To begin with, what I lost on this upgrade road was time. I spent most of yesterday afternoon going through various motions to try to get the Insider Preview for 27788 and a companion KB5053390 (CU for .NET Framework…) up and running. All such attempts, alas, proved fruitless.

Traversing That Long Hard 27788 Upgrade Road

Getting to the state depicted in the lead-in graphic — showing that the Lenovo ThinkPad X12 Hybrid Tablet is up-to-date in WU and running Build 27788 in Winver — took some doing and some time. In fact, it wasn’t until I read about a workaround in an ElevenForum post from Russian user @Dronix that I made any real headway. Along the way, each update/upgrade cycle took about 1:10 (70 minutes) to work through.

I’ll deliver a recitation of what I tried that didn’t help my problems. I am also speculating when I say this, but I believe one can’t upgrade to 27788 until KB5053390 for .NET completes successfully. There may be dependencies in the upgrade that need the previous CU to complete successfully. And indeed, once I did that, the upgrade went through without further issues.

Here’s my list of failed strategies:
1. Simply retry the failed KB or upgrade item.
2. Run Eleven Forum’s Reset_Reregister_Windows_
Update_Components.bat from this Reset WU tutorial
3. Run the built-in WU Troubleshooter

What Worked: DISM-GUI 1.3.1.02

Turns out there’s a German software tool named DISM-GUI that lets one install KB .cab files from failed installations. You have to know the name (a partial name will do) of that file to provide it as a target. The afore-linked Eleven Forum thread identifies it, and it includes the KB number as a sub-string. Using Voidtools Everything, I found it immediately (search string *KB5053390*.cab). For the record, the filename is:

Windows11.0-KB5053390-x64-NDP481.cab

Click on the box in DISM-GUI that reads “CAB Install” (lower left) and the program will prompt for the file location. You can get that from Everything, then left-shift click and use the “Copy as Path” option (you’ll have to delete opening and closing quote marks).

This opens a Command Prompt session and uses DISM to install the package for you. Unlike the WU driver install, this actually works. And it takes less than two minutes to complete. Then, when you’ve got the CU installed, the follow-up upgrade to 27788 works, too.

TLDR: Possible Problems with 27788 Are Fixable

If you read through the whole Eleven Forum thread about 27788, some posters were able to install KB5053390 and the 27788 upgrade without any difficulties. Numerous others — myself included– got exactly nowhere until they used DISM-GUI to get over the KB5053390 hump.

Should you find yourself in the same boat, you can go straight to the workaround using that tool, and avoid the hours and hours of thrashing about I went through yesterday. Why not learn from my experience, instead of repeating that misery?

Providing such info explains why I write this blog. It also explains why I expect lifetime employment doing that kind of thing here in Windows-World. It’s always something…

But Wait! There’s More… (Added Jan 7)

When I logged into the X380 and the X12 this morning, KB5053390 again showed up as needed. And again, a regular WU install failed. So this time, I fired off DISM-GUI taking the left-click “Run as administrator…” option. Apparently that did the trick. Here are some screencaps along the way:

Between the 2nd and 3rd screencap, I ran DISM-GUI again (as admin) and it showed a successful conclusion at the command line, then reboot with successful update there after). Once I rebooted the system and it worked through the rest of the process, I got the 3rd figure above from WU. Gadzooks! I hope it’s finally over…
