I have a MS Intellipoint Laser Mouse 7000 V7.0 installed. When I went to\ninstall V7.1 this windows update KB970158 tagged along with my knowledge\nor permission. MS doesn't even list a description as to what it is. What\nwas odd was that id didn't come thru the normal windows update screen. I\nuninstalled it and my mouse stopped working. I uninstalled V7.1 and went\nback to V7.0 and everything now works again. Can anybody tell me this is\nabout?
