UPLAY is not entirely restricted to where your games are installed. You can install UPLAY anywhere on any Drive, and choose where to install games ie into different hard drive paths. What I mean is that, just install UPLAY whethever drive you want, and there's an option in UPLAY called "Locate Game Folder" just like in this video bellow -

Then locate where your games are currently installed and the app will do the rest with the file checking and download stuff. Your games doesn't necessarily needs to be installed in Games folder either.
