This tool will decline ALL driver updates on the WSUS server.
I wrote this tool as a result of the thousands of driver updates just released to the WSUS servers. All those extra driver updates lead to performance issues on the WSUS server as clients connect for their detection cycles and as you bring up the WSUS updates page. By declining the thousands of driver updates you can improve the performance on your WSUS server.
Note: This tool was written for WSUS3 SP1. I'll try and get a RTM (SP0) version shortly.
