Windows Update problem with KB5101650 and KB5120249

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.

    Hi, thank you for patiently waiting. After checking and analyzing the event logs, I found multiple NTFS (Disk) errors on the PC. This could indicate that the particular KB update is conflicting with the file system, or that there may be an underlying file system error.

    In this case, I suggest doing an in-place upgrade, which will upgrade the device to the latest version and repair all issues without deleting any files.

     

    Note: Before doing this, make sure to create a restore point:  https://support.microsoft.com/en-hk/help/4027538/windows-create-a-system-restore-point

     

    1. Go to this link: https://www.microsoft.com/en-us/software-download/windows10
    2. Select Download Now, and select Run. You need to be an administrator to run this tool.
    3. On the License terms page, if you accept the license terms, select Accept.
    4. On the What do you want to do? page, select Upgrade this PC now, and then select Next.
    5. After downloading and installing, it should fix the issue.

    Hi, I'm Bernard. I'm happy to help!

    The KB's that are causing the issue are an update fix for bugs. Since you are encountering system errors, can you please check the System logs on the PC so I can further examine the root cause of the issue?

     

    To share the System logs, please follow the steps in the link below:

     

    Press the Windows key + X, then select "Event Viewer"

    Click the drop-down of "Windows logs"

    Right-click System > click Filter Current logs > Check: Critical, Warning, and Error > Hit OK

    On the right pane, click "Save Filtered Log File As..."

    Save the System logs file to your desktop and share it by following the steps from the link:

    https://support.microsoft.com/en-us/office/share-onedrive-files-and-folders-9fcc2f7d-de0c-4cec-93b0-a82024800c07

     

    Note: You can also use your preferred cloud storage to upload and share the logs.

    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:

    1. Uninstall the problematic update
      • Open Settings > Windows Update > Update history.
      • Select Uninstall updates.
      • Remove the update that triggered the freezes.
    2. Pause updates temporarily
      • Since uninstalling restores normal operation, pausing updates is the practical workaround to prevent the same update from reinstalling immediately.
    3. 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.
    4. Check for newer replacement updates
      • Open Settings > Windows Update > Check for updates.
      • A newer update may replace the problematic one.
    5. 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.
    6. 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.
