Why is my Windows 11 laptop randomly restarting after the latest update?

After installing the most recent Windows 11 update, my laptop restarts randomly while I’m working, no error messages or warnings. I’ve checked for overheating, ran virus scans, and even did a clean boot. Nothing helped so far. Has anyone else had this issue? Any fix?

I had a similar issue after the 2025-07 cumulative Windows 11 update. What worked for me was uninstalling the update (via Settings > Windows Update > Update History > Uninstall updates) and then doing a clean reinstall of the chipset and GPU drivers.

Also, check Event Viewer under “System” logs. In my case, it pointed to a power kernel error related to the Intel Management Engine. Updating that driver from the manufacturer’s site (not via Windows Update) fixed the random restarts.
