How to Reset Local Group Policy Objects on XP to default settings

After much searching on how to do such a simple task as reset local GPOs back to their defaults, I finally found the real answer. I tried this on Windows XP, although it is said to work for 2000 and 2003 Server as well.

1. If you need to clear IPSec settings and software restriction settings do these two sub-steps, otherwise go on to the second step:
a. reg delete hklm\software\policies\microsoft /f
b. regedit /s "c:\policies.reg" (where c:\policies.reg is the exported hklm\software\policies\microsoft hive of a virgin or target configured machine)
2. Issue this magical command to reset the rest of the GPO settings to their defaults (enter this all on one line):
secedit /configure /db reset /cfg "c:\windows\security\templates\setup security.inf" /overwrite
3. Delete the registry.pol file if it exists:
del c:\windows\system32\grouppolicy\machine\registry.pol

4. Reboot
