add/modify registry file using group policy.

I need to add a key in the HKCU branch of the PCs.  Can I do that using group policy?

If I create a bat file to call this reg file, do I just copy both the bat and the reg files to the "Show Files" window from the Logon properties and add the bat file by clicking Add in the Logon properties?  

Our DC uses Windows 2008.

Please advise in steps as I have never done this before.

Thanks in advance.

Here is an idea of how to go about this:

The Easier Way

We’re just making a simple registry value change here, so why not use REGEDIT.EXE in silent mode to set it? To do this we:

1. Export this registry value to a file called SciCalc.reg
    Windows Registry Editor Version 5.00
    [HKEY_CURRENT_USER\Software\Microsoft\Calc]
    "layout"=dword:00000000

2. We create a new Group Policy object and link it to the OU we have configured for all the administrative users in the domain (ourselves and our super powerful colleagues).

3. We open it up and edit “User Configuration | Windows Settings | Scripts (Logon/Logoff).

4. Under the Logon node, we add our settings so that regedit.exe calls our SciCalc.reg file silently (with the /s switch):

You would need to create a reg file for this:

So the login script would load regedit.exe and silently add the info in your reg file


    Windows Registry Editor Version 5.00
    [HKEY_CURRENT_USER\Software\Microsoft\Calc]
    "layout"=dword:00000000
