With all of the rush to get Windows patched due to the vulnerability and the issues surrounding the Zebra printers, i have tested the patch on Windows 10 Pro version 1909. It refuses to install.

I have come across multiple articles stating that it will not install on 1909 pro because it's end of life.
I know the option to upgrade these machines to 20H2 is possible. We are currently working on that.

So, with the above said, can this patch be installed on End of Life versions of Windows 10.

    No, this Windows Print Spooler Remote Code Execution Vulnerability can’t be installed on Windows 10 Pro 1709, 1809 and 1909. Your test has proved this point.

    From Microsoft Security Vulnerability document, we can see that:
    UPDATE July 7, 2021: The security update for Windows Server 2012, Windows Server 2016 and Windows 10, Version 1607 have been released.
    All versions of Windows are vulnerable. As of July 7, 2021, Microsoft has released security updates for this vulnerability for all supported versions of Windows listed in the security updates table in this CVE.

    As we know, Windows 10 Pro Version 1909 end of support on 05/11/2021, Version 1809 end of support on 11/10/2020 and Version 1709 end of support on 04/09/2019. So all of them no longer belong to supported versions of Windows, can’t install the PrintNightmare CVE-2021-34527.
