0xC004F211: Hardware Change Occurs if Windows detects a significant hardware change (e.g., replacing the motherboard).	A Windows license is tied to your device's hardware. Significant changes, like replacing the motherboard, can cause Windows to lose the license. If Windows was preinstalled and you changed the motherboard, you’ll need a new license.

Enter a different product key or buy a new product key. You upgraded to Windows 11, but the activation servers were busy. If you upgraded from an activated copy of Windows 7 or Windows 8.1, your copy of Windows 11 will be automatically activated, or you can wait a while and then select Activate. If you continue to have problems with activation, contact Keyzing Support for help. You upgraded to Windows 11 using the free upgrade offer, but Windows 11 isn't activated after a reinstall. Your copy of Windows 11 should automatically be activated as long as you didn't make any significant hardware changes to your device (such as replacing the motherboard). If you continue to have problems with activation, contact Keyzing Support for help.
0xC004C003	This error occurs because the Windows 11 product key you entered is not valid. Product keys are unique and assigned to a single device. If a key is used on multiple devices, it becomes invalid. To activate Windows, you’ll need a different, unique key for your device. Contact Keyzing Support for help.
0xC004F034	This error can occur if you entered an invalid product key or one for a different version of Windows. Enter a valid product key that matches the installed version and edition of Windows 11.
0xC004FC03	You might see this error if you're not connected to the internet or your firewall settings are preventing Windows from completing the activation process online. Make sure that you're connected to the internet and your firewall isn't blocking Windows from activating.
