Always go to the hardware manufacturers website for current driver updates. MS has proven to be unreliable for providing such as this.
Better luck next time.
I had to buy a new mouse 2 weeks ago because I installed a MS update for my MS mouse drivers-- and the mouse died. (Was ok I needed a new one anyone.. broken left click button).
So, today I went to the Windows update site and did a custom SW check and lo and behold, there are new drivers available for my NEW MOUSE. So, I downloaded those.
Well, same thing happened. Mouse died again. I eventually got it working by unloading the drivers entirely and letting plug and play redetect it, so it's no big deal.
Entirely possible it was the same update downloaded 2 weeks ago with new names attached (new mouse is by KYE old one was MS but both are optical scroll mice).
Or, conspiracy theorist that I am, there is something wrong with the Windows updating and it installs the drivers in the wrong place (I honestly think this is possible, but since Windows doesnt tell you where it is installing the drivers-- it just does-- I can't be sure).
Anyway.. it's just "interesting" and not a problem but I thought it was worth mentioning.
