Can you transfer your Windows license between PCs? It depends–the answer isn’t so cut and dried.
Why You Might Want to Move a License
Transferring a Windows license (aka product key) isn’t something the average PC user will ever need to do. Most people will purchase a computer with a Windows license preinstalled. When they upgrade to a new computer, the new computer comes with its own Windows license.
Note that transferring a Windows license is different from actually moving an entire Windows installation to a new computer. That’s a lot harder to do, and it’s usually better to just perform a fresh install on the new computer if that’s what you need.
Here are a few examples of situations where you might want to move a your license to a new computer:
In other words: if you already have a valid license lying around and don’t want to buy a new one, you’ll want to transfer it.
A License Can Only Be Installed on One PC at a Time
PC No matter what type of license you have, you can only have it installed on one PC at a time. That’s Microsoft’s rule. So, while you may be able to move a license to another PC, you’re supposed to remove it from the first PC before you do that. You can do that by wiping the PC’s hard drive or evenuninstalling the key from your Windows system.
Large organizations can acquire special “volume licenses” that allow them to activate multiple computers with the same license key. However, that’s the only exception to this rule.
Always Allowed: Replacing a Motherboard Because It’s Broken
You can upgrade a lot of hardware components without Windows freaking out, including the graphics card, RAM, and hard drive. But Windows doesn’t normally allow you to replace your computer’s motherboard. When your computer gets a new motherboard, Windows considers that an entirely new computer and will deactivate itself.
While Windows won’t normally allow you to upgrade your computer’s motherboard, there’s one exception, as far as we know: If your motherboard fails and needs to be replaced, you can move your Windows installation to the “new computer” with the new motherboard.
This exemption should be available no matter which type of license you’re using. It ensures you don’t have to buy a new Windows license for a PC if its motherboard breaks. However, to take advantage of this exemption, you’ll have to contact Microsoft via the phone activation process. You may have to talk to a representative and explain what you’re doing, or the automated system may just work.
Never Allowed: Moving a Preinstalled License to a New PC
When you get a computer that comes with Windows system preinstalled by the manufacturer, the Windows license will always remain tied to that computer.
There’s no exception to this, aside from the exception for replacing the computer’s motherboard if it failed, as discussed above
Manufacturers get these non-transferable licences for less than you’d pay for a transferable license, hence the restriction.
Always Allowed: Moving a “Full Version” or “Retail” License to a New PCPC
If you buy a “retail” “full version” license–this is generally only something you do if you’re building your own PC, installing Windows on a Mac, or using a virtual machine–you can move always move it to a new PC.
After you move your license several times, Windows may give you an activation error and ask you to call Microsoft to activate your computer. Microsoft’s representatives will allow it. They just want to make sure you aren’t installing the same license on multiple PCs at a time. As long as you only have the product key installed on one PC at a time, you’re good.
Maybe Allowed: Moving an “OEM” or “System Builder” License to a New PC
