Windows Update problem with KB5101650 and KB5120249

Steve E 5

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.

I can confirm a very similar issue with KB5120249.

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.

Same to me!!!
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!

Yes—similar issues have been reported with KB5101650, including freezes and input problems after installation. In this situation, the supported actions in the available guidance are:

Uninstall the problematic update

Open Settings > Windows Update > Update history.

Select Uninstall updates.

Remove the update that triggered the freezes.

Pause updates temporarily

Since uninstalling restores normal operation, pausing updates is the practical workaround to prevent the same update from reinstalling immediately.

Try Windows Update repair if the update has already reinstalled or cannot be removed normally

Open Settings.

Go to System > Recovery.

In Fix problems with Windows Updates, select Reinstall now.

Check for newer replacement updates

Open Settings > Windows Update > Check for updates.

A newer update may replace the problematic one.

If devices stop working after a major update, run Windows Update again

Microsoft notes that after some major updates, recently updated drivers might not migrate correctly.

Running Windows Update again can locate and reinstall missing device drivers.

If mouse or keyboard problems continue after updating

Test the mouse and keyboard on another PC to confirm the hardware still works.

Then open Device Manager, locate the affected device, open Driver tab, and select Update Driver.

Based on the described behavior, uninstalling the update and pausing updates is the clearest workaround currently reflected in the available guidance.
