KB5045934 Dot Net?

Topic

Hey Y’all,

I ran into an interesting situation while running updates. Unfortunately, I didn’t get a grip on the initial cause but I think it was the KB listed.

Process:

1. Take Image Backup of daily driver (currently on Win 11 Pro 23H2.
2. Run Windows update for the Dec. updates. That was quick and easy!
3. What say we give 24H2 another chance, disabled GPO to allow update and run.
4. Run my program to show update info. PowerShell window shows up but it’s blank! I fish around to where the Exit button should be and click and it closes the program. Tried to bring up Windows PowerShell ISE to debug with the ISE opening but no data in window, couldn’t even open the code.



5. Try 5 other PS programs all with the same result.
6. Ok, bad update is suppose and go into WU and uninstall. Unfortunately, even though it did “an” uninstall I’m not sure what got uninstalled as the machine was still on 24H2 26100.2605! However, now the programs all work…



7. Ok, let’s run WU again and see what happens, that’s when it finds KB5045934 and installs it. Everything still working after this.

Not exactly sure what happened here but all is working correctly for the time being.

Ok Y’all,

Problem with KB5045934 CONFIRMED!

I tried running Minesweeper “classic game” and found it missing.
Reinstalled from my saved .zip file and the same problem window w/o contents.
I uninstalled the KB and now everything is back to normal, at least w/MineSweeper.

Off to PS to hide that update for now.

Hey Y’all,

This gets curiouser and couriouser by the minute.

All is well on my “Canary” machine Intel Processor (7th Gen Processor and TPM 1.2 “not supported”) and running Win 11 Pro 24H2 26100.2605. The KB in question was installed on 11/12/2024!

On my daily driver AMD Processor (Ryzen 7940HS, TPM 2.0) many programs will not run.

• MineSweeper (Tried both Win7 & 8 compatibility modes)
• Windows PowerShell ISE
• Any PowerShell program using XAML display code.”

Uninstall the KB and all is well!

Hey Y’all,

Well I solved the problem…but first!

That darned KB5045934 reinstalled it self, even though I had it hidden!

PS> get-windowsupdate -IsHidden

UM790PRO     -D--H--    KB5045934  142MB 2024-11 Cumulative Update for .NET Framework 3.5...

I finally remembered that there were some issues with having StartAllBack installed while doing updates…

1. Checked for latest version of SAB – .13 and I was running .12.
2. Uninstalled .13.
3. Rebooted
4. Everything works again…
5. Installed .13.
6. All is good!
Note to self: Self – in the future uninstall SAB BEFORE doing monthly updates then reinstall latest version!

I still don’t understand how this jimmied things the way it did, but that’s above my paygrade!

FYI: “Canary” had been upgraded to .13 but for some reason I hadn’t update my daily driver.

Happy Holidays to one-and-all!

I always check that SAB is on the latest update BEFORE I update Windows

For those of you who’ve been paying attention you’ll notice that this thread is no longer marked resolved. Yes it’s back!

So I figured the only way to figure this out was to restore my Image Backup from before I started this update quest. So I got it back to 23H2 fully patched through November 2024.

So here goes (I kept much better records this time)

1. Restore 23H2 Win 11 Pro 23H2 226311.4460
2. Clear windows update cache.
3. Verify all affected programs work, more than once!
4. Verified no Dec. updates installed.
5. Uninstall StartAllBack version 2.8.12.
6. Reboot.
7. Verify programs again.
8. Install SAB 3.8.13 (per PK Cano’s suggestion)
9. Reboot.
10. Verify programs again.
11. Take a new Image of fully functioning 23H2 C: drive only.
12. Apply Dec Updates KB5048685.
13. Reboot after update reboot.
14. Verify Programs again.
15. Take new Full Image of 23H2.
16. Remove Block in GPO on 24H2 update.
17. Check for updates (24H2 found).
18. Install 24H2 followed by 2x Reboots.
19. Verify programs all OK!
20. Shutdown and go to bed it’s late!
21. Next morning “It’s Baaaack!”
22. Reboot.
23. It works for a while then programs fail (Windows PowerShell ISE, Minesweeper.

At this point I’m at a total loss. As far as I can tell once I run MineSweeper successfully the problem reappears. I’ve run the troubleshooters and have the compatibility setting on Win 7.

Note: KB 5045934 is NOT installed?

Ideas?

Wild card:

Add a check in the Minesweeper Compatibility box to “Run as Administrator.” Does that do any good?

Ok, this continues…

Further testing

1. Uninstall StartAllBack.
2. Tests still fail.
3. Reboot.
4. Tests – work initially then fail over the space of about 5-10 minutes.
5. Reboot.
6. Don’t attempt to open Minesweeper. Test other stuff. Fail after a while.</l>
7. Check Device Manager…No caution signs!

Conclusion: So at this point in time I’ve eliminated StartAllBack and MineSweeper as the cause. Of course I have no Idea what is causing the abhorrent behavior.

Ok, figure this one out…I went to get a screen shot (Snipping Tool) of the PowerShell ISE window. Pressed Win+PrtScr and the ISE window appears as it should???? Try the same trick with MineSweeper and it fails and now trying to open ISE fails. I can’t get it to repeat that either!

Ok Y’all,

This time it is resolved!

Verdict-WINDOWS LIES!

Since I had eliminated MineSweeper and PS ISE as culprits I decided to reinstall StartAllBack. This time I decided to do it via WinGet vs using the download I had so I went to fire up PowerShell Core 7+ (since I couldn’t get to the ISE). And below is what I got.

Well, that’s some new information…

I fired up the old search engine and it immediately pointed me to DRIVERS!

Being one of those who believe in the “if ain’t broken’ don’t fixit” school of thought I trusted what Windows told me when I looked at Device Manager.

Well, that was misguided for sure. I went to the AMD site and there were a bunch of things to download (4 in all) including some chipset drivers.

Downloaded, Installed, Tested (over time) and all is well again.

This is the first time I’ve had a non-Intel device so lesson learned. Weird things happen check drivers at AMD site!

Now off line to re-image my fully functioning system!!!!!
