I never did this b4 nor i have any idea if this work. pls tell me if this works or not.. right now i have 100% working OS with softwares n there updates. OS with software is in C: drive n nothing more in it. size is about 6.5GB. say i have backed up the entire C: drive in DVD, n due to some reason i had to format my OS drive erasing all da softwares n updates. if i install da OS again after formatting, is it possible dat i copy paste/overwrite the OS with the back up i made consisting of da installed softwares,updates. will the running OS allow overwriting? or i'll i have to overwrite it in dos mode, n if in dos mode then what will be da commands for it. gets fed up with installig softwares wasting time in updates...so was wondering if i can cut the installing n updating part as i have quite a lot softwares installed. I use winxp pro as my OS. thank u.
