One of our readers has sent this question a long while ago and now I remembered it after seeing it on the Microsoft community forums. Here’s how the issue sounds like. Maybe you found yourself in the same situation and are looking for the answer.
Installing on 2 devices with single key. I have two devices on my own.A laptop and a PC.I had purchased windows 8. Can I install it on both devices with the same key? Is it legal? Does it affect my Windows update process?
Windows 8.1 on more devices with the same key – possible?
Long story short, here’s the answer extracted from the installation and usage rights sects on the terms and condition page while installing Windows 8.1. Of course, nobody reads it until the end, hence the questions.
a. One Copy per Computer. You may install one copy of the software on one computer. That computer is the “licensed computer.”
b. Licensed Computer. You may use the software on up to two processors on the licensed computer at one time. Unless otherwise provided in these license terms, you may not use the software on any other computer.
c. Number of Users. Unless otherwise provided in these license terms, only one user may use the software at a time.
d. Alternative Versions. The software may include more than one version, such as 32-bit and 64-bit. You may install and use only one version at one time.
So, there you have it – you will need separate keys for every computer. Of course, this is such a pity, especially, if, say, you have Windows 8 laptop, an AIO and a desktop unit, on top of that.
