run > regedit > file > export ;)
then import again when you've reinstalled the OS.
just found out about this, was curious if it was possible. my reg dump is about 65 MB, seems realistic.
I got Vista to boot in safe mode again, but not safe mode with networking (clue!). I ran regedit, and backed up the registry to a different drive. I also did a diskcheck, and there were numerous errors corrected, but not in the file records themselves.
In the past, with XP, there were times I've gotten past a problem with booting the system by doing nothing more interesting than running in safe mode and restarting.
So I restarted, but no joy. So I restarted the Vista Installer, no joy, can't find anything wrong with startup. Tried a restore point. There weren't any. The problem still exists, apparently, where an XP install wipes out your Vista restores. (Or something approximating that.)
So then, at a restart, I get the multi-boot menu, and hit F8. Only this time, I did something I didn't expect to workólast good configuration. I didn't expect it to work because there were no restore points. I didn't realize that there are OTHER things Vista keeps around that I know nothing about.
Because it came right up, and has run perfectly ever since. And I did a full backup once again, and intend to copy it, and the program to restore it, to an off-board drive THAT I WILL DISCONNECT BEFORE I MAKE THE NEXT SERIES OF MISTAKES.
All of which is to say, I confess to n00bhood (I designed major software systems, including the autopilot for the B2, have a Master's in Comp Sci from UC Berkeley, and I hate windows so much I've never really tried to understand anything but BCDEDIT and the registry.)
So I ordered two deep books from Microsoft Press on Vista, and am eagerly awaiting the rewritten OS manual due in January. I am inspired by my ignorance, and want the damned thing to overclock to the moon.
