I think someone has the same trouble. After the black Tuesday of October, I cannot use Remote Desktop to my server whose OS is Windows7 Home Premium (x86). Actually, I had not thought it was the black Tuesday before I found this fact (-_-;). Remote Desktop to Windows7 Home Premium, you can understand what I say, can’t you? I found this and this and tried their suggestion for enabling the feature again. But failed, and gave up. Oops!
Honestly, it is very inconvenient that I cannot use Remote Desktop to the server. So I decided to use Chrome Remote Desktop instead. I don’t like another software installation that is not needed for the server itself, but I have no choice at this time (Sigh).
