That happens because Windows 10 and Windows 11 are storing the hardware clock differently:
One is treating it as local time, the other as UTC.
When you swap between the two systems, the clock jumps by a few hours.
Fix (pick one):
In Windows 10/11, run regedit → go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation
→ create a DWORD (32-bit) value called RealTimeIsUniversal and set it to 1.
(This makes Windows use UTC like Linux/macOS.)Or just disable automatic time sync and set time manually, but that’s less reliable.
👉 The registry tweak is the clean solution — then your clock will stay correct when switching between Windows 10 To Go and Windows 11.
Want me to give you the exact .reg file you can double-click to apply the fix directly?
