Obnovitev sistema ne deluje

Po dolgem času,sem upurabil ukaz "obnovitev sistema" in ves presenečen ugotovil,da mi ta ukaz ne deluje.Prav tako ne najdem nobene obnovitvene točke.Pa tudi če mu dam, da naj naredi obnovitveno točko,mi napiše,da naj ponovno zaženem računalnik in potem naredim obnovitev,seveda pa ko to naredim je pesem enaka.Obnovitev ne deluje!Lahko pa povem,da je obnovitev vključena in da mi tam ne javlja nobenih težav.Le v čem je problem???Ali je mogoče,da je kak virus??Uporabljam vindows xp in vista 64 v dual boot,za antivirus pa a-squared anti malware,...

hvala jan01, toda to ni odgovor,ki si ga želim

Za Windows XP poskusi s to REG datoteko (cut and paste v Notepad in shrani kot SystemRestoreFix.reg) - dvoklikni in dodaj v register (TO SO ORIGINAL VREDNOSTI ZA SYSTEM RESTORE IZ SVEŽE NAMEŠČENEGA XP-ja).

Za Windows Visto pa trenutno ne najdem datotek kako popraviti System Restore, bom dopolnil kasneje...
