Over the past 6 months I have gotten microsoft updates that make my wireless keyboard and mouse stop working. Only way I have been able to fix it is to hook up a wired mouse and then do a system restore. This has happened at least with 10 different updates. Keyboard is Logitech K330 and mouse is Logitech M215. I am running Windows 7. Dell computer and mouse and keyboard are from Dell. Any ideas on how to fix this problem?
