I tried this solution for installing APPS to the SD card and now none of my Apps will work. I then "refreshed" the Surface Pro, after which I can't install any Apps from the store and I can't use any Apps either.
I have tried this myself yet, but the easiest way is to reinstall your apps after making the modifications. Otherwise you need to make a symbolic link for the C drive app location to the SD card location or modify each and every registry entry for each app. Both sound more risky and painful.
Did you just move your existing installed apps? I doubt that Refresh will do anything in that case, since the registry entries for this applications will point to there original locations.
