Automatically Deleting a Registry Key

Normally you cannot automatically delete registry keys from reg file. But there is a way...

Simply include a minus sign inside the left bracket before the main key.

For example.
If you want to delete the key HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Office \ 8.0 \ Common \ Assistants, your regfile would simply look like:

REGEDIT4

[-HKEY_LOCAL_MACHINE\Software\Microsoft\Office\8.0\Common\Assistants]

This would delete that key and any below it.
