0xc004c003 activation error in windows 11 pro after installing ver 22H2 upgrade

Question

Hi, I purchased a new computer with OEM Win 11 Pro. The OS was activated by the supplyer. After installing Win 11 ver 22H2 upgrade I got the message "Windows should be activated". During activation I got the 0xC004C003 error code.

Any suggestion?

Hello there,

Error code 0xC004C003 is a Windows activation error that typically occurs when there's an issue with the product key or the activation process itself. To resolve this issue, you can try the following steps:

Check Product Key:

Ensure that you are using a valid product key for Windows 11 Pro. Go to "Settings" > "System" > "Activation" and click on "Change product key." Enter the correct product key if necessary.

Restart Your PC:

Sometimes, a simple restart can help resolve activation issues. Restart your computer and check if the problem persists.

Check Windows Activation Servers:

Occasionally, the activation servers may be experiencing issues. Wait for a while and then try activating again later.
