Is anyone else experiencing system crashes after installing the most recent Windows 11 update?

Hi there,

My computer has crashed two or three times today, and the only recent change I can think of is installing the latest Windows 11 updates. The system doesn’t stay on the error screen long enough for me to read the full message. It briefly freezes, then switches to a black screen showing “0%” at the top, and at the bottom it references something about a “Kernel Stop” error. However, it restarts too quickly for me to capture the exact details.

I suspect the issue may be related to either the 2025-10 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 (KB5066131) or the 2025-10 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5066835, build 26100.6899). I installed both updates, restarted the computer, and then shut it down for the night. The crashes started the next day after turning it back on.

Any suggestion would be appreciated!

    I have a Dell machine and while the Dell software attempted to resolve the reboot loop it failed several times. Be attempting a F12 start several times I finally found a Microsoft recovery method to restore a previous state (i.e. before the update that crashes the machine). Then I quickly paused the updates for about two weeks (I set it for a month). This week I turned off the get updates early option and updated KB5081277 and KB5079473 yesterday and they completed successfully.

    Good Luck
