Deactivate Windows Product Key and Use on Another Computer

Whenever you buy a new Windows computer, you get a copy of Windows 10 pre-loaded. However, when you choose to build a custom PC, you need to purchase a Windows 10 license. But in case if you do have an old Windows 10 computer and you wish to transfer Windows 10 license to another computer. Then it is absolutely possible.

This approach is extremely cost-saving. Plus, if you are selling off your old PC or replacing your old system, this approach surely saves you from buying a new Windows 10 license. And in this article, I will be talking about how you can deactivate the Windows product key and use it on another computer.

Determine if you can transfer Windows 10 product key to another computer

Before you go ahead and transfer your existing computer license to a new one, you have to ensure that you can do so. You can type the following command to find out the type of Windows key.

slmgr /dli

slmgr check Windows key type

Note that while in my case it says MAK, in your case, it can be OEM or Retail or something else.

Microsoft uses different channels to distribute Windows 10 licenses. As a result, consumers can only obtain a license using two channels that includes retail and original equipment manufacturer or OEM.

So if you do have a retail license, you can transfer your product key to another device. If you upgrade to Windows 10 from Windows 8.1 or 7, you can also transfer the retail license to another computer.

Plus, there is no limit on how many times you can transfer a license. Just make sure you are deactivating the license from the previous computer, and you are good to go.

However, if your computer came with Windows 10 preinstalled, it means you are using an OEM license.

In such a case, the Windows 10 product key cannot be transferred, and you are not allowed to activate it on some other website.

Even if you are upgrading to Windows 10 Pro from Windows 10 Home purchasing the upgrade through the Microsoft Store. Then you are allowed to transfer the license to another computer. Your product key will turn into a digital license linked to your Microsoft account by purchasing an upgrade.

The easiest way to activate the Windows key is to link it with your Microsoft Account. As soon as you link an admin account with a Microsoft account, the license is instantly linked with your account.

So next time when you switch to another computer and choose to activate, Windows will prompt with the machine name of your previous computer and ask if you would like to transfer the license to your new machine. 

If you install it on the same machine, Windows will activate it in a maximum of few hours.  You can always run the activation troubleshooter and get it sorted.

So that was all the steps you have to follow to deactivate the Windows product key and use it on another computer. Now go ahead and try out the steps and see if they are working for you.
