It happens for last month. After some time randomly my Windows 8.1 starts acting weird instantly. My mouse left click changes to double click, right click stop working at all, keyboard stop working at all, start screen and button not working at all, that menu that pop up when you mouse to right down corner does not appear at all. Clicking at anything in the taskbar open a new instance of it. Loging off does not help I can only hard restart which helps. I am sure it is windows related because Start does not work as well. Is there any update Windows did to f*** up everyones PC? I have laptop.
