hit the scan driver button. now this is one of their improved features. it now only scan drivers that don't come on the xp cd instead of every last driver like the old version did. back them up to a folder.
reinstall windows then double driver. hit restore and locate your old driver files then hit restore. the old version of dd would only restore one folder at a time while also having a millions folders. this resore all of them
viola. you are done. it's that easy
the best part is you don't have to wait for a virus to backup your system. back it up now.
