Everything has become very slow after upgrade from Windows 8 pro to 8.1 pro. Google Chrome used to snap open and now there is a lag for about 6 to 8 seconds. There is also a lag after sign in. There are other lags also, but those are the most significant ones. I don't have the other problems with shut down and power on, it is the same as before. I removed hibernate from command prompt. I cloned my hard drive before upgrading and am debating going back unless there is a solution, does anyone have one?
