Asus windows 7 x64 So I got the corrupt registry (Yay me!) error and can't get into anything like normal, safe mode, etc. I can get into the command prompt. I can't run system restore as there are no restore points and startup repair doesn't fix it. I also replaced the the registry files in system32\config with the backups in regback, but to no avail. So here I am, hat in hand, in need of assistance. I have several questions. 1-I have seen you mention a registry cleaner on your site in the FAQ I think it was. Can I put this on a thumb drive and run it to fix the registry? 2-In the X: drive, there appears to be a system default version of the registry files SAM, SYSTEM, SECURITY, etc dated from 3 years ago. Can I put those in C: to fix the problem? 3-I would rather not have to do a OS re-install. But if I must, I don't have a recovery CD. Instead, Asus put all the recovery info on a separate drive E:. Is there a way to do a system install by accessing the files on E: via the command prompt? I would be grateful for any other suggestions (if they work that is) Edit: I forgot to mention that I can access the registry editor. Is there a way to tell which items are corrupt and possibly fix them from the editor?
