I need to edit a corrupted system.dat file (windows registry), I have a copy of access to this file. How do I open and edit this file using regedit?

You can open another "hive" with regedit.
However, this will only work on Win2k/Xp/Vista/7, there is no way to load the registry like his in Win9x/ME.
1No good. System.dat is for windows 9x :( – Hugh Allen – 2009-11-05T23:39:15.557

I wonder if a different tactic would be better? Restoring an old system.dat.
Do some operating systems keep system.old or system.something?
Booting into safe mode? Running regedit.
What I am thinking is even if you could edit it, could you repair it?
This file belongs to a Virtual Machine, i tried boot in safe mode but the windows initialization fails. – RRUZ – 2009-11-05T22:37:36.337
I know exactly which registry key change to repair the file, as this was damaged by a malicious vb script. – RRUZ – 2009-11-05T22:42:18.793

If you have a copy can you just overwrite the bad file? Otherwise you can use your favorite binary editor. I use Hex Edit Neo. They have a freeware version also. www.hhdsoftware.com
You should probably say that you are using Windows 95/98/ME. – Hugh Allen – 2009-11-05T23:40:37.613
Please clarify exactly what version of Windows this question relates to. – Kez – 2009-11-06T00:05:44.863
