Black background Windows 7 while a background is configured through GPO

Today I’ve a strange problem in my testlab! I’ve installed a copple of Windows 7 virtual machines and joined them to the domain. The testusers using roaming profiles whit some folder redirection to the home drive.

When the first user logged in, the desktop was completely black! Nice, but there’s a background configured in the Group Policy…..hhhmmm! This is a known bug by Microsoft and there’s a hotfix available, KB977944
After I installed the update, reboot my virtual machines, everything works like a charm 😉
