I've tried all of the suggestions made to no avail. I guess at this point I will just revert back to Win7
wait up. Not yet. I may have some tricks up my sleeve that might just help.
Don't ask why, just try them. It solved my mouse problems in the past or from others.
1. Turn off pc, unplug your mouse, start on pc, put back in in different usb port. When it's says 'installed' or something confirming, start up UED again. Fingers crossed.
2. In general, mouses do not need drivers. Some do, check the manufacturer if there is any available. Try that.
3. Since the software changed, and not your hardware, uninstall your mouse in the computer managent panel > device manager, uninstall your mouse, unplug your mouse, restart pc, put mouse back in.
Hope of any these help, otherwise I need to think of something more advanced.
