Do you know the history of the license on this computer? Can you find out from your friend if this computer originally started with Windows 7 or 8?

Can you please type cmd in the search on the taskbar and hit enter to launch the command prompt, then run the following command:

slmgr /dlv

Then share a screenshot please.

Error 0xC004F211 means Windows detected a significant hardware change and can no longer match the current device to the existing license.

What to do:

Open Start > Settings > System > Activation.
Select Troubleshoot.
If the troubleshooter cannot fix it automatically, look for the option to reactivate after a hardware change.
If there was a product key previously used on this device, select Change product key and enter that 25-character key.

Important detail for this scenario:

A Windows license is tied to device hardware.
If Windows originally came preinstalled on the PC and the hardware changed significantly, such as the motherboard, a new license may be required.
The hardware-change reactivation path works when the license was linked to the same Microsoft account before the hardware change.

Since the computer was inherited from another person, activation depends on whether the existing license is transferable and whether there is a valid product key or linked digital license available for this device. If Activation shows Go to Microsoft Store, that is the path to purchase a new Windows license.
