You might be wondering How Many Times Can You Use A Windows 10 Key?

Windows product keys raise a lot of questions. You cannot re-install Windows without a legitimate and unique product key, which is why there is so much interest in finding out the Windows key code.

There is no limit to the number of computers you can install Windows on if you use the same product key.

However, this is illegal and you won’t be able to activate Windows on more than one computer at once.

There is a period of time when Windows must be activated in order to continue using the operating system.

Thus, although the installation is completed successfully as long as the product key is valid, Windows does not function fully unless the product key is activated with Microsoft’s server, and usually, only one product key may be installed on one computer at a time.

So, what about transferring your windows 10 license key to a new computer?

We will get to that next.

You may be able to move it to a new computer if required, depending on the type of Windows 10 license you have enabled. Microsoft has distributed its desktop operating system across numerous business channels over the years.

New machines will also come with an OEM license preinstalled. Microsoft distributes Windows on many other platforms, including Retail, Volume License, University, and subgroups, such as Update licenses.

Microsoft released its new update, Windows 10, in 2015, offering the operating system free of charge for eligible PCs and computers running Windows 7 or 8 for a limited period of time.

For computers without a qualifying license or for individuals who develop PCs, Microsoft continues to offer Windows 10 as a complete retail product.

Determine whether you can transfer your Windows 10 license

Make sure you know what type of license you have installed

According to Microsoft, Windows 10 free upgrade is a full version and not a trial. Despite these statements, Windows 10 free upgrade does have an expiry date.

  • Windows 10 license derived from a retail copy of Windows 7, Windows 8, or 8.1 – can be transferred. But under Microsoft’s rules, only a one-time transfer is allowed.
  • If you have upgraded from a Windows 7, Windows 8 or 8.1 OEM license, these are licenses that come from a manufacturer preinstalled on a new device, and then the Windows 10 license retains the OEM rights that can not be transferred. 
  • With a full retail copy of Windows 10, you can transfer it an unlimited number of times.
  • If you upgraded from Windows 10 Home to Windows 10 Pro Pack using Digital Licensing, you can transfer it. This is possible because of the Pro Pack, although it is an upgrade, it is still a retail license attached to the Microsoft account used to purchase it.

Formerly, you could tell where a particular license came from by issuing a particular Windows command.

In the November Update it is clearly mentioned that all licenses, regardless if they are full package or OEM, are considered retail.

Although Microsoft describes the free upgrade from Windows 7 OEM or Windows 8/8.1 OEM to Windows 10 as retail, it is still an OEM license at heart.

This relates to what you can do with the license. If it is retail, you can continue making hardware modifications to your system such as replacing components or moving it to a different computer. For an OEM version, if you replace components on automatically, your free upgrade will be revoked, meaning you will need to purchase a new full retail Windows 10 license.

Microsoft recently released a feature that makes it easier to transfer licenses to new machines using the Digital License feature. This is one option you should consider when transferring a license, check out our article for details about how it works.

Remove the License and Transfer to Another Computer

To transfer a full Windows 10 license, or the free upgrade from a retail copy of Windows 7 or 8.1, the license must no longer be in use on a PC.

Windows 10 does not have a way to deactivate it. Instead, you have two choices:

  • This is the closest thing to disabling the Windows License by uninstalling the product key. This approach would not warn Microsoft Activation Servers that the license is no longer used on the machine; instead, if Microsoft Activation Servers were to detect the license in use on more than one device, it would prevent conflicts down the road.
  • Format the machine-This process guarantees that the license on the computer is no longer in use. With Windows 10, you can use the easy reset option to do this.

How to uninstall Microsoft Windows 10 Product Key

Press Windows key + X and open up Command Prompt be sure to be in Admin mode. At the command prompt, enter the following command:
