While trying to boot my Windows 8.1 OS I was able to make it seen as a Windows to Go OS, while now I moved back the HD internally.

In order to enable BitLocker I need to remove the "Windows to Go" setting from the OS, however I didn't find any way to do it from the UI.

Does anyone know how to revert the "Windows to Go" flag in Windows 8.1?


Run this command from a cmd prompt with admin rights:

reg add HKLM\SYSTEM\CurrentControlSet\Control /v PortableOperatingSystem /t REG_DWORD /d 0

The value PortableOperatingSystem is the flag you want to change. If it is 1, Windows Thinks it is a WindowsToGo.

  • That was the setting! Thank you, worked like a charm. – Michele Di Cosmo May 25 '15 at 14:09
  • @magicandre1981 - Would/ could the reverse be true as well? Can a regular Windows be flipped by simply that one flag.. to make it WTG? – Alex S Sep 1 '15 at 8:30
  • @AlexS I never tried it – magicandre1981 Sep 1 '15 at 15:25
