Windows 11 25H2 doesn't maintain precise timing by default.
on my 4790k system i installed 25h2 using rufus and added shutup10, explorer patcher and windows aero to customize it. i’m puzzled by the time issues—it used to happen while loading into windows but now only during reboots. i’ve looked up online and found possible reasons like a bad CMOS, though windows 10 seems stable as a tri boot system. my other two computers with 25h2 don’t have this problem, and i didn’t encounter it before switching from 23h2. recently i searched for solutions but haven’t found a clear fix. if i click “sync now” in settings, it syncs correctly, but the next reboot messes up the time—only the hour is affected, not the minutes.
Only the timing matters—check if everything aligns with the right timezone. Ensure daylight saving adjustments are accounted for.
It's 7, 10, and 11. Not using Linux. Apologies for the unclear message earlier.
I checked the BIOS settings and found they were wrong. I fixed them, but now all three operating systems display the incorrect time at startup. After syncing to the right time, booting into another OS still shows the same wrong time before syncing again. It keeps happening. What could possibly be causing this?
