Windows – Delete registry key or value via a CMD script

command linewindows-registry

How do I edit an already-in-production .cmd script file, in order to have the script delete a certain registry key in the Windows registry?

Firstly, is this even possible, and secondly (if that's not possible), could I create a .reg file and execute that file from with the .cmd file?

From within the .cmd script, it is not working:

del "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CurrentVersion\SampleKey]"

This method hasn't worked for me either:

cmd "\\networkdrive\regfiles\deleteSampleKey.reg"

Then from within the .reg file:

Windows Registry Editor Version 5.00
[
-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
]

Best Answer

I would recommend using the REG command, rather than creating and importing .reg files.

reg delete "HKCU\Some\Registry\Path" /f

or 

reg delete "HKLM\Some\Registry\Path" /f

These commands can be entered directly into the batch (.cmd) file.
