Cannot change Support Phone Number in Vista

462 Views
Last Modified: 2012-08-14
I am trying to change the phone support number on the System page through the registry. I have done this on literally thousands of other domain and non-domain machines but there are a couple new ones that won't let me change it.

So I change the registry key here to read (999)123-1234:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation\SupportPhone

I go here >Control Panel>System to verfiy the phone number has changed.

I then run gpupdate /force and the phone number changes back to the original (to include the registry!)
I have looked all over group policy to find if there is a security setting that is reverting this back but I can't find anything.

Does anyone know where this setting may be?

I checked the flags on the subkey and they are the same as other machines that retain their settings when changed:

C:\>reg flags HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMIn
formation QUERY

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation
        REG_KEY_DONT_VIRTUALIZE: SET
        REG_KEY_DONT_SILENT_FAIL: CLEAR
        REG_KEY_RECURSE_FLAG: SET

I understand the concept that the registry change related to that application will be redirected to something like the HKEY_USERS\S-1-5-21-1234567890-1234567890-123456789-123456_Classes\VirtualStore\MACHINE\SOFTWARE

Currently there is nothing in any of the redirected subkeys. Is there some place else I need to look?
