OEM keys can generally only be used once, retail can be used as many times as you want, as long as only one system is using it at a time.

 

Officially anyways.

So, if a Windows key is activated is it only available to use for one computer and one computer only? Does it depend on the version of Windows like 7/8/8.1/10? My version of Windows 8 and 8.1 let me use the key several times and I can use them over and over again for multiple computers but this key I got for 7 Professional only worked once, so like does it depend or something?

Unless you buy a very specific version of windows you can only activate each key once.

Okay thank you, I must have some very strange copies of Windows then... O.o 

 

I guess retail is the way to go then
