Looks good! I wholeheartedly endorse using cmd scripts for anyone who doesn't want PowerShell. I only wrote my verion that way because once I switched over I swore I'd never write another cmd script again :P

If anyone wants to use BobGnarly's script on Vista I think that all you would have to do is:
1) Replace "hardlink create" with "mklink"
2) Replace all of the "junction ..." lines with "mklink /d ..."
