yes and depending on whether you want the user’s profile or the system you should(could?) format the call with what is returned from GetWindowsDirectory or GetSystemWindowsDirectory.
Just depends on where the drivers were installed. If the drivers were install while the system was in install mode then they should be in the system if the drivers were installed and the server wasn’t in install mode then they could have ended up under the user’s profile. It is somewhat common.
