The method in that KB article is not foolproof.
The File copy/paste method does not seem to preserve symbolic links properly, it copies the files and folders, not the links.
Also, the desktop target might have 8dot3names disabled, as it does for me, so you have to find a temporary spot with short filenames enabled.
Basically, I have found that once you disable 8dot3names, and remove those old directory entries, you really can't go back. Or at least I don't know how to do it. Maybe ROBOCOPY can do it, but I didn't want to dig into that.
Weird how relics from the DOS days still haunt us.
