Remote Desktop Virtualization Host could not apply a user profile disk for a user account with a SID of S-xxxxxxxxxx-xxxxx-xxx. A temporary profile could not be enforced for the user because the guest operating system version is not correct. The user will get a normal profile, and the user's state will be discarded when the user logs off from the virtual desktop. Verify that the user profile disk settings are correct.
