Question : ADM template for an environmental varible

I need help creating a custom ADM file that I can use as part of my group policy for setting a system evironmental varible. I can't seem to find the spcific information how to do this.

The system environmental variable I would like to set is:
%WINSYSDIR%
and I would like to set it to the following path:
C:\WINDOWS\system32

Is this possible?

Answer : ADM template for an environmental varible

If you prefer to this by Group Policy, you will need to reboot the machine for it to take effect, below is the ADM. I made it so that it can be applied to either a machine or a user, using either "Computer Configuration" or "User Configuration"

Machine Configuration writes it to:
"HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

User Configuration writes it to:
"HKCU\Environment"

The key is a REG_Expand_SZ so will allow variables for instance, you can use %Windir%\System32 as the value rather than C:\Windows\System32.

Cheers
