My video card is NVIDIA GeForce 7600 GS and I am running Vista Ultimate sp1. Some time ago I updated the driver via "Update driver" in the video card properties window. The installation seemed to go ok, and I had no display problems, except that whenever I logged onto an account, I would get a UAC window asking to finish the installation of the driver. If I clicked ok to proceed, it would finish installation and tell me that the installation was successful. If I clicked "Remind me later" of course the box just went away, but the driver version number was still the same. Well, this was annoying to have to do with every log on, so I rolled back to old driver. Result: I still had to finish installation -- this time of the old driver -- with every logon. Next step: download the latest driver from NVIDIA (version 22.214.171.12450, dated 3/27/2009). Again the installation seemed to be successful, but I still have the same problem with a UAC window asking me to finish installation with every logon. I checked the NVIDIA support site but can't find any mention of this problem. Any ideas? As I say, I am having no display problems, just the annoyance of having to jump through this same hoop so often, for no apparent reason.
