Fix Incorrect Clock Settings in Windows When Dual-Booting Linux

If you dual boot your Windows PC with Linux, you may have experienced a problem in which your clocks reset themselves incorrectly every time you boot into Windows. Here’s a simple registry edit to fix that.

Essentially, the incorrect clock setting happens because  Linux use GMT time while Windows tries to synchronize with your local time zone, getting confused when you reboot between the two.

To fix it, just hit Start and type regedit.exe in the search box. Hit Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation. Right click anywhere in the right pane and hit New > DWORD (32-bit) Value. Name it RealTimeIsUniversal, then double click on it and give it a value of 1.

Lastly, reboot into Linux then reboot back into Windows. You should now notice that your clock actually displays the correct time.
