The Group policy Client service failed the sign-in
I have seen this error first time you try to login on a newly SCCM 2012 R2 deployed Windows 8.1 computer. The Group policy Client service failed the sign-in. The universal unique identifier (UUID) type is not supported. This is only happening when I use the original RTM ISO en_windows_8_1_enterprise_x64_dvd_2791088.iso
