I had to re-install windows Home because of problems. The I remembered before the problem, 3 years ago when I build the computer I added Windows Professional by on line. I tried to do that again (re purchase). I had the option of using the key or on line I connected on line and o=got the key. Now when I try to upgrade, it goes through the motions but I still show 24GB Ram 16 GB usable. (which is why I went to professional in the first place was to use more ram.
Is there something I am supposed to activate? I don't think it installs anything.
