What is Windows 10 Activation Error 0xC004F211?
Windows reported that the hardware of your device has changed.
A Windows license is associated with your device hardware. If you make significant hardware changes, such as replacing your motherboard, Windows won’t be able to find a matching license the next time you start your device. If Windows was preinstalled on the device and you have made a change such as replacing the motherboard, you’ll need a new license.
How to fix it?
1. You can buy new Windows 10 product key
To purchase a new Windows license, you go Start > Settings > Update & Security > Activation , and then you select Go to Microsoft Store.
Open Activation settings
2.You can reactivate Windows 10
If you have a Windows product key you used on your device before the hardware change, enter it by selecting Start > Settings > Update & Security > Activation , and then selecting Change product key.
Additionally, Microsoft provides an exception path for transferring a Windows License after a hardware change. You’ll need to be signed in to the same Microsoft account before making the hardware change and to use the exception path.
To access this exception path, select Start > Settings > Update & Security > Activation , and then select Troubleshoot. If the troubleshooter can’t resolve the issue, you’ll see a link to reactivate after a hardware change. Select it to follow this path.
