Why Am I Getting a Windows 10 Activation Error?
Review this section to identify why you’re getting an activation error in Windows 10.
Your Copy of Windows Is Installed on Multiple Computers
If you’re using a pre-owned computer, it’s possible that the seller used the product key on more computers than microsoft allows. Activation may fail to work if you have one copy of windows installed on multiple computers. You can ask the seller to give you the original product key and windows dvd.
If you try the windows dvd or product key and still cannot activate your computer, or the seller doesn’t have them, you may have to buy a new product key or copy of windows. Alternatively, you can reach out to the microsoft support team if you continue to have problems with activation.
Missing Product Key or Digital License
To activate Windows 10, you need a Windows digital license or 25-character Windows product key. If you don’t have either of them, you’ll get the Windows activation error.
Counterfeit Software
If you’re using a counterfeit copy of Windows, you won’t be able to activate it. You can visit the Microsoft How to Tell site to find out whether your copy is counterfeit or genuine.
Different Version of Windows or Different Product Key Was Used During Repair
If you’re using a different version of Windows or Windows was activated before you repaired or rebuilt your PC, you’ll get a Windows activation error. The same applies if a different product key was used during repair.
In such cases, reinstall your original version of Windows and re-enter the product key that came with your original copy of Windows or with your computer.
Substantial Hardware Changes
Windows may no longer be activated in cases where you replaced your hard drive or motherboard, or made substantial hardware changes to your computer recently. This is because Windows won’t find a license that matches your devices, meaning you have to reactivate Windows using a product key or digital license to get it working again.
How to Sync the Microsoft Digital License
You can confirm whether your Microsoft account is associated with your digital license in a few quick steps.
- Select Start > Settings.
- Next, select Update & Security.
- Select Activation.
- The Activation page should display a message that reads: Windows is activated with a digital license linked to your Microsoft Account.
- Go to https://account.microsoft.com on your browser and sign in to your Microsoft account.
- Select Devices. If you see your computer listed in this section, it means your digital license is linked to your Microsoft account.
How to Fix Windows 10 Activation Error
While Windows 10 can work without activation, we don’t recommend it because some features will be disabled, and Microsoft may decide to delay or block updates altogether making it unsafe for you to use. Plus, it can be illegal to use Windows without a proper license especially if you’re using it for commercial purposes.
Here’s how to fix activation errors in Windows 10.
Check Whether Your Computer Is Running Windows 10 1607 or Later
Before you can fix any of the Windows 10 activation errors, check whether your device is up to date and that it’s running Windows 10 version 1607 or newer versions.
Type winver in the search box on the taskbar and select Winver to see the Windows version and build on your PC.
Note: If your PC is running an older Windows version, learn how to update Windows 10 to the newest version.
Use the Activation Troubleshooter
The Activation troubleshooter helps fix several Windows activation errors caused by significant hardware changes, issues with the Windows digital license or reinstalled Windows.
Note: The Activation Troubleshooter is only available if Windows isn’t activated on your PC. Also, you have to be signed in as an administrator. If you’re not, you can create a local user or admin account to start using the troubleshooter using the steps below.
