A buddy of mine wen't crazy and bought a Vista Ultimate Upgrade for his Hp Vista Home Premium . It seem that he run some kind of wizard to upgrade, but when it restarted it didn't have any of the sofwares installed neither the data. He told me the he found a Windows.old folder on C:\. Is it possible to rollback to Vista Home after that vista ultimate upgrade? Should the data still be somwhere in the computer? Any help would be greatly welcome.
