So I turned my pc on today and found out I've got a corrupted registry. The computer won't let me boot into windows normally. I can only boot into the system recovery option. I tried a system restore but that did not work. I read on a different thread that the best solution is to reinstall windows. I wish I didn't have to go that route because I have a lot of data that has not been backed up. But, if that's what I have to do then I want to know how I can use command prompt to transfer my files to an external hard drive. I'm running the newest version of windows 7 release candidate. All help is appreciated.
