ok so this is what happened . .. i installed wubi yesterday and i was using it earlier . then i remembered that i mistyped my windows username wrong so in my windows directory c>user>"Adrain Paul" i changed it to "Adrian Paul" (im using ubuntu during that time) then i restarted my computer to switch back to windows 7 but it told me on startup that it is preparing my desktop. and that i was accessing only something temporary




and i remembered that i renamed my folder using ubuntu. i looked back at the users folder and saw Adrain Paul & Adrian Paul. Adrain Paul has a lock on its folder but Adrian Paul doesnt have. i merged them but still nothing happened . . .huhuhu help me please . ..



note: Adrain Paul is mistyped and should be Adrian Paul . ..
