I was following your guide to revert back to XP from vista when I ran into problems trying to rename the files to .vista. The system couldn't find the boot, Config.Msi, Documents and Settings, MSOCache, and Recycled folders. Also, when renaming * to *.vista it didn't take any time like the guide said it would. Since I didn't want to mess things I reverted the names of the folders I did rename back to normal and used the startup repair to get back into vista. I'm lost and would like some advice, thanks.
