Hi, I bought Windows 7 Professional 64-bit about 10 years ago and installed it to a MacBook Pro as a bootcamp partition. I am retiring the old laptop but I would like to install Windows 7 on a new machine perhaps natively or as a virtual machine. I want to reuse the license. How do I deactivate and disconnect the license from the old machine so that I can use it in the new machine? About 20 years ago, I just called Microsoft and they just issued me a new key. Don't know about now.
