:tard: Actually, you can edit the registry without using ERD.. At least, I have no problem doing so with WinPE. All you need to do is run regedit, and then select HKLM. You can then go to file and load hive. Browse to C:\Windows\System32\Config\. You'll see files named System, Software, etc. Select the one you wanna modify and call it whatever you want (like Local_Software). Then modify the hive you've loaded, be sure to unload it and you're done.
