You have also an old Windows version. You have the 19041 version and it is the May 2020 update. You can upgrade it via windows update. It should appear as "Feature Update to Windows 10, Version 21H2" or similar.

Or you can use an update tool from Microsoft:

But with the update tool the upgrade will take very long.
