How to find and replace in regedit?

I use win_xp_sp3 inside my virtualbox i was mapped all the xp folder destination into my host machine in regedit. and now i need to change the my username and i don't remember all files i changed. is there any possibility on regedit find and replace?

There are a few paid products out there (with with free trial periods), for example:

• RegEditX
• Registry Replacer
• Registry Toolkit

For a 'free' option you can try:

1. Exporting search results from RegScanner
2. Use a text editor to search and replace in the exported .reg file
3. Import the updated .reg file to update the registry.

Just remember to backup your registry before you do anything! :)

Something like ERUNT should help for the backup.

I stumbled across this free Advanced Regedit thing. Seems to work.

The best, free one out there - Registry Finder

Hosted on its own HTTPS page, so it doesn't look that much of a security risk to me as others that can be only downloaded from sourceforge.com or similar.
