Windows activation error 0xc0ea000a usually appears when hardware-level changes are made to the device. If this error appears, it means that the motherboard has been changed and Windows has been reinstalled, or the system has been crashed and the activation key has been uninstalled. Other possible causes are network issues, incorrect product keys, or an unlinked digital license.
Since we have identified the possible causes of this problem, let's explore the most effective solutions to get rid of this error message.
1. Run the Activation troubleshooter.
If you have made hardware changes to the system, such as replacing the motherboard, you can try running the Activation troubleshooter. When you activate Windows, Microsoft stores the activation state and links it to the motherboard, so you don't need to activate Windows every time you install it on the same device.
- For that, click Win + I and open Settings.
- Go to System > Activation and run the troubleshooter.
- Now, simply follow the on-screen instructions to run the troubleshooter.
2. Check Microsoft account
Another common cause of this problem is that you are not signed in with the correct Microsoft account that you used to purchase a license key. If you sign in with the correct Microsoft account, you should be able to reactivate Windows.
- Open Settings > Accounts > Your info.
- If you are signed in with a different account, go back to Accounts and then open the Email & accounts page.
- Click Add account and follow the on-screen instructions.
- Once you are signed in, try to reactivate Windows by following step 4 of method 3.
3. Re-enter product key or reactivate Windows
If you have a product key, you can re-enter it to activate Windows again or you can turn on automatic online activation using a couple of commands. These commands will contact the Microsoft server to activate Windows using the digital license linked to your motherboard.
- To do so, press the Win key and type Command Prompt.
- Right-click on it and select Run as administrator.
- As an administrator, type the following command to activate Windows: slmgr -ipk slmgr -ato
- If you have a digital license key, you can use the following commands, but make sure you are signed in to the Microsoft account that has a digital license for Windows: slmgr.vbs /ato slmgr.vbs /dlv
- Once you’ve done this, the error message should be fixed.
4. Contact Microsoft Support
If nothing works, you can try contacting Microsoft Support, especially if you change any hardware on your device, such as the motherboard. The support team may be able to provide a direct solution or walk you through phone activation.
