M$ are trying nasty tactic's to get users to upgrade to win 10 ..... in the form of the mouse bug. the mouse bug from hell that is. If you have win 7 with sp1 and you update you will probably get the mouse bug. I updated system on the 01/08/2016. the bug dose not show itself straight away it's a gradual thing it start's first with double clicking in your program's sometime's multiple time's then the icon you clicked on will end up being moved and so on and so on till you end up pulling your hair out. checked mouse thinking my mouse was on it's way out in another computer all was fine put it back in my system same thing I then checked the driver's all was latest drivers for the mouse saying no problems... The only way i got it back working again was to do a system restore to the date before i did the update lucky for me it was enabled.... I normally have it disabled. M$ fortune 500 company trying to get customer's to update to win 10 <<<< Fecking nice try M$ and when you ask at M$ support guess what they said ..... Update to windows 10 LOL HAHA ne fecking way.
