A virus snuck it's way on my system system. I have removed it, but would like to revert the registry back to before the virus just in case it messed with my windows security settings. I ran system restore, but of course that didn’t work (never seems to work after a virus), so I did what one normally does for windows XP: I copied the sam, system, security, default, and software files into C:\windows\system32\config folder using NTFS DOS. This always works in windows XP, but it doesn’t work in XP 64-bit, as when I boot the system back up, all the settings are current. Not only that, I am copying the hive files from before I installed one of my games. But after copying over the files, and rebooting, the game registry entries are still in the registry. x64 has another registry backup, does anyone know where it is? These are the things I have tried, but nothing reverts the registry settings back to before I got the virus: 1) Totally emptied C:\windows\system32\config, and only copied over the 5 main registry files. I even deleted the the systemprofile directory. 2) Deleting snapshot registry files out of subsequent RP664, RP665, RP666, RP667, ect. (I though x64 may be re-loading in the latest registry entries from those snapshot locations. 3) Also replaced the _REGISTRY_USER_NTUSER.... files in the correct location (in the user profile directory), as well as the _REGISTRY_USER_USRCLASS.... files in the correct location, and of course renaming. As soon as I reboot the computer, the computer has the latest registry settings, it doesn’t go back in time. Does anyone know where X64 has a secondary set of hidden registry files, or how x64 keeps on knowing what the latest settings were? Thank you Angie
