If I buy one copy of Windows Professional can I install it on different PC’s with the same product key or will it automatically block it? When you put CD key after previously using it does it block it or does it continue with the installation and than block you out later? Thanks in advance.

You can only use one product key for one computer..
It will not allow you to enter it into two or more computer..
You can install it more then once but it will only give you days free until you enter your product key..
you can try buying windows family pack (up to three computer) for about $ dollar

Hello.
I think it’s allowed as long as your Windows is beta version or evaluation copy. If it isn’t, your other PCs which has Windows Seven installed will be blocked when you are connecting to internet.
Windows Evaluation Copy is same best as completed Windows . You can update them for free.
Might help you.

The retail version will allow you to install the OS on multiple computers. An OEM version of Windows will only work with one computer at a time.
i think you can install it but you need to activate it. you cannot activate with same key on different PCs..
