Really the only way to do a user vs computer license is to have a cloud based system (which MS has).

I second the freezing issue. I often times have to wait 10 to 15 seconds for my mouse to unlock amongst the other issues. I was trying to install Libre office and it just wouldn't show the GUI (process was running. I killed it several times and tried again). I ran out of time and then came back and tried it again and it worked fine. This is a Lenovo core i7, 6 GB RAM with a factory built install. It was a black Friday deal or I wouldn't have even purchased Win 8.
