I am using a desktop computer and it's very old. Recently i have setup my pc with WINDOWS 8.1 . At fast it was ok but as the day goes its becoming slow. I have searched on internet for solution and have downloaded a software called speedy pc pro. But it was a trail version. It speed up my pc a little. The problem is now it wants speedy pc pro license. I have searched in torrent sites for pro version but i didn't manage it. If anyone have any better solution for speeding up my pc or how can i upgrade it on pro version? If you have solution please info here or pm me. Thanks!
