Deleting Registry Keys from the Command Line

There are two ways to delete a key from the Registry from the Command line.

At the MS-DOS Command line: C:\Windows

RegEdit /l location of System.dat /R location of User.dat /D Registry key to delete

You cannot be in Windows at the time you use this procedure!

Or you can create a reg file as such:

REGEDIT4

[-HKEY_LOCAL_MACHINE\the key you want to delete]

Note the negative sign ” – “just in between the “[” and the HKEY

Then at the Command line type:

RegEdit C:\Windows\(name of the regfile).
