A while ago I blogged how to re-enable remote desktops MMC for Windows Vista. This feature has different names and it was hard to find initially :) In a comment one reader posted a way to enable it via “Programs and Features” – > “Turn Windows features On and Off” as suggested to search for “Remote Server Administration Tools"\"Role Administration Tools".
With Windows 7 it is different.. again. But this time no file copy and DLL register. First you need to download and install Remote Server Administration Tools for Windows 7.
And then navigate to “Programs and Features” –> “Turn Windows features on and off”:
Hope this helps
