Both these recent Windows Updates are not working properly for me. They install without problem, but after approx 6 minutes, the whole system freezes, inc mouse, keyboard etc. Only option is to shut down at the power. On restart it does the same thing again - freezes after 6 minutes.
Only option is to Pause updates, uninstall the relevant update, reboot and then everything's ok again.
I am running Windows 10 Home. KB5101650 was installed on 18 July 2026 and today I tried to run windows update again and it pulled down KB5120249 instead - both causing the same problem above.
No recent hardware changes in the last 12 months, so any help would be appreciated. Guessing others have encountered similar problems?
Thanks.

My PC is a Dell Inspiron 3647 with an Intel Core i5-4460S and Intel HD Graphics 4600.
The system was freezing completely: the screen remained frozen, mouse and keyboard stopped responding (including Caps Lock), and remote access was also lost. The only way to recover was a forced shutdown.
I performed a clean installation of Windows 10 and did not install any updates. The computer then remained stable for over 24 hours.
After installing the Windows updates, the freezing returned. I checked the update installation history and identified KB5120249 as the main suspect.
After uninstalling KB5120249, the computer has remained stable again so far.
This strongly suggests that KB5120249 may be causing compatibility or stability issues on some older hardware.

I learned that the KB5120249 was from 11th of August 2026. And till today, the 5th of September 2026 there is still no correction available from Microsoft? Since when is it well known that this update makes problems? Why was the update not removed from rollout from then on?
I tried to uninstall the update, but ran during this action again into the 5 minutes freeze problem. So I don't know the status of my PC. Is the update still installed, is it uninstalled, is it partly in- or uninstalled?
Together with the AI it lasted some hours (!!!!!) and it is still not solved. Thank you Microsoft!

2026-08-30T05:10:05.5233333+00:00 Hi, thank you for that information. What I can highly suggest is to post the issue on the Feedback Hub so that developers will also be aware of this problem, and hopefully the fix will be applied as soon as possible.

2026-08-23T17:07:36.33+00:00 Hi again. Tried this today but it didn't resolve the problem. The in-place upgrade worked, but it pulled down the offending update - KB5120249 as the final update download. PC then froze after approx 5 mins. Something must happen 5 mins after the Windows Desktop appears. I don't have a TPM installed, as PC is too old for that, although Win 10 shouldn't need that anyway. BIOS is set to secure boot and I can't think of any other reason why it crashes.
There's only just enough time to uninstall the update before it crashes too.
Is there a way to download updates manually, so this one can be ignored?
