hey, sorry for the WIHU ... cause i'm new in the forum. but the secret of the tool is that it uses the WMI classes from .NET it's a standard for asking some informations of a machine in local or on a network. It uses a SQL syntax like : "select * from win32_Video..." Now it's was tested on the nvidia and ATI drivers but it can be uses for SOUND, MASS STORAGE, NETWORK CARD, or others devices (keybords, mouses, modems, etc ...) I makes this because i detect that my geforce was not installed with the new 61.77 forceware, but with the last one, it was ... so that's make me fool. I seek on the net and find some people who have the same troubles. The thing i never understant it's why it doesn't install even if it found the good hardware (ex for my case : it install the nvdia GeForce common driver given by Microsoft) Good information for bad installation. WMI unattended solve the problem. But WMI is a completement from the OEMpnpdriverspath, not the only solution.
