MDT Scripting: Deleting Registry Keys

A lot has happened since I wrote my articles on MDT Scripting last year. For one thing, I’ve learned how to compile my code in a script block on my blog.

Two of my readers have asked about deleting registry keys using MDT Scripts but there does not appear to be a function for it in the ZTIUtility.vbs.

I’ve knocked up something quickly. It’s a simple function devoid of error handling. It will delete a key named  “HKEY_LOCAL_MACHINE\SOFTWARE\ScriptimusExMachina\Unwanted Registry Key”

		' Call function and delete key
		Dim sRegDeleteValue, sRegKey
		sRegKey = "HKEY_LOCAL_MACHINE\SOFTWARE\ScriptimusExMachina\Unwanted Registry Key"
		oLogging.CreateEntry "Preparing to delete Registry key " & sRegKey, LogTypeInfo
		sRegDeleteValue=regDelete(sRegKey)
End Function
</script>
</job>

Any issues with this, remember to read my first article Hello World.

    Hi Andrew,

    Before Anything else, Thank so much for the great post. Sorry to bother but I’m hoping you can help me. I am trying to run this script on a Windows 8.1 machine and i keep getting errors.

    I verified and re-verified that i could delete the key by using reg delete HKEY_LOCAL_MACHINE\SOFTWARE\cnb command successfully. Any pointers would be appreciated. Thank You.

    Hi Andrew – So i have a registry key called
    HKEY_LOCAL_MACHINE\SOFTWARE\ZOHO Corp\ManageEngine AssetExplorer\Agent\
    inside that registry, there is a key called AgentId – how can I delete JUST THAT KEY when running this script?
    Thanks in advance for the help.
