Windows 7: Software Questions

Windows Ultimate 64bit w/ sp1
Software Questions

I bought a home built computer from a friend that is pretty good with computers. It worked great and I had no problems with it but decided to build an upgraded one myself. I used the hard drive from the old one and have started getting a message that the Windows home build system software isn't registered properly or some nonsense like that. The system still works fine but I get this message after the computer is on a while. Upgrades from Windows seem to work fine. Since this started, I read where OEM software only works with the original motherboard. Could this be the source of the notifications? If so, can I buy another OEM software and re-install it over the old one without loosing everything? Does it have to be ultimate version or can I use home premium?

If you changed the mobo then OEM version dies with the old mobo. Sometimes with a good reason MS phone activation will activate it for you anyway.

If not you can buy online at a major retailer like NewEgg or Amazon and insert a new OEM product Key at Computer>Properties Activation link to activate it. If for some reason that link doesn't appear then use the slmgr command below to insert key and activate.
