Operating System

I tried to use the two of the most popular computer operating systems which are Windows 7 and Linux in the  past a few semesters. I think Windows 7 got very successful improvement from Windows Vista. I remember that when I used Vista system, it makes me to feel angry and a blue screen death often happens to me and makes me to restart the computer. Sometimes when restarting does not work, I even need to restore it to an original state. Windows 7 does not have this problem and have a better user interface and faster speed than Vista. Linux is a also a convenient OS and it can use the terminal to do many operations. I don't like to use the command line user interface to operate a system because I can't remember these many commands and I sometimes spell words wrong and make the command invalid.
