At the C:\Users\User\AppData\Local\VirtualStore\Program Files\World of Warcraft the only folders i have are these:
Cache
Logs
Screenshots
WTF

and 1 file
Scan.dll.new

No Interface directory. Maybe i should just take the entire new location and put it back to crogram files>wrld of warcraft ?

Edit: the path where wow folder was placed by vista is this: C:\Users\Public\Games\World of Warcraft
There exists the folders WTF, Interface and Cache as well as all the other folders and files we know, including the launchers
