Hey kap, no need to get an activation code for your Windows 7 as long as you can get a DVD that is branded for your device. For instance, if you use a Dell DVD to install the OS onto the Dell device it will automatically pull the activation/registration key over without any hassle at all. I do this all the time at work.

Also, if people are using Windows 8, you can get a little free app called Classic Shell and it will make Windows 8 appear to run like Windows 7, no Metro/tiled look.

This desktop was given to me. It did not come with any install CD/DVD.
but you can find a free/cheap DVD somewhere. The activation key is expensive and you don't need that.
