If your Windows 10 activation lost after hardware change or upgrade, this article will show you the steps to re-activate your system.

To fully enjoy features on Windows 10, you must have it activated. To activate Windows, simply go to Settings app > Update & Security > Activation and click Change product key link and type 25-character product key and click Activate. Windows will be activated within few moments.

But the real challenge with activation is after hardware change. Usually, Windows activation is linked to unique ID which in turn is linked to system hardware such as motherboard etc. So if you change hardware on the machine, the unique ID is also changed and it results in loss of activation.

To avoid this problem, Microsoft introduced digital license/entitlement method. Using digital entitlement, your Windows license can be linked to Microsoft account. When you switch to Microsoft account from local account on activated Windows 10, your digital license will be automatically linked to your Microsoft account. You can also do this manually by following steps mentioned in this guide.

With digital entitlement, the activation is stored on Microsoft servers, along with your system hardware. Since you changed system hardware, you can use digital entitlement to restore activation on your Windows 10 machine.

So here are the steps you need to perform, to re-activate Windows 10 after hardware change.
