451438 2006-05-02 10:33:00 The advice given before doing anything to the registry is to always do a backup - "because if you mess it up you may not be able to even get your system to run at all"....So if I do mess it up to that extent how can I then get to restore the backup version of the registry???? peepholenz (10337)

451440 2006-05-03 03:03:00 I wouldn't consider using regedit as a good way to recover, from anything but the most trivial changes, however here you go:

"How to back up the whole registry

To back up the whole registry, use the Backup utility to create an Emergency Repair Disk (ERD), or back up the System State (which includes the registry, the COM+ Class Registration database, and your boot files)."

451441 2006-05-03 03:41:00 The question revolves around what to do if Windows cant even be started.

The original registry that was made when XP was first installed can be restored using Recovery Console.

Then hopefully Windows can be started and a good system restore point used to get back into a state before things turned to custard:

Edit: Windows 98 was much better in this respect because DOS could be used to restore a registry immediately using scanreg /restore

451443 2006-05-03 05:39:00 Thought I'd better test out the advice given, always a good idea :)

Following Kellys-Korner, I booted from XP CD, went into Recovery Console, and renamed the System and Software files in c:\windows\system32\config, then copied those files from the \repair folder. Then re-booted, the odd program like Diskeeper complained a bit because there was no registry entry for it, and also new hardware found, since the system had changed a bit since first install.

Ignoring that, went into System Restore, called up a previous restore point, and re-booted.

All went ok, Windows re-booted, no problems, and back to original state.

This method is probably better and safer than doing a repair install from CD.
