    Use this to verify instead:

    Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo}

    Now check the returned value against Table 1 to validate that you’ve got the right file version.

    Patched systems file versions
    Exchange Server 2019 For CU7: 15.02.0721.013 For CU8: 15.02.0792.010
    Exchange Server 2016 For CU18: 15.01.2106.013 For CU19: 15.01.2176.009
    Exchange Server 2013 For CU23: 15.00.1497.012

    Hi @BR0KK ,

    It seems that the Update KB5000871 superseeds the update KB4602269

    Yes, and this is mentioned in the Security update replacement information of KB5000871:

    When it comes to verify the installation of the patches, as suggested by Andy, you can use the command he shared or run the HealthChecker script(Recommended). For more details, hopefully you can find the official link below helpful:
