If you get this error at the first logon after Windows 10 OSD:
“The Group Policy Client service failed the sign-in.
The universal unique identifier (UUID) type is not supported.”
Here is the solution. Source: https://support.microsoft.com/en-sg/help/2976660/first-logon-fails-with-the-universal-unique-identifier-uuid-type-is-no
Add a Run Command Line step at the end of the task sequence:
cmd /c reg add "HKLM\SYSTEM\CurrentControlSet\Services\gpsvc" /v Type /t REG_DWORD /d 0x10 /f
Finally, restart the PC and sign in to windows without errors 🙂
