Amongst the all versions of the windows operating system windows 8.1 is the most dumb os and its very slow comparitively and its boot animation is too boring .i have to change a lot of things in it it has lowest technology .i think windows xp must be better than it. I feel too buzzed using it .so I uninstalled and deleted its file and downoaded windows 7 which is better option .actually all my friends hate the windows 8.1 too.
