Hi
What version is your Windows?
Windows 10, version 2004 is available for users with devices running Windows 10, versions 1903 and 1909, who manually seek to “Check for updates” via Windows Update. If you’re running older version of Windows, it is better to perform a Clean Install of Windows, please back up all your data before the clean install.
