I check the previous tab in the properties menu and it older version IS the windows folder which is pretty confusing. And I gonna update to Windows 10 21H1 because I think it will install a newer installation I guess.Can I just use the reset option instead? Can you help me verify that folder is not a virus or something because I feel worry when I reset a physical computer. Also, Is it safe to keep it in my computer? Because I gonna upgrade to Windows 11 when it release officially though.
