I've Exchange 2013 CU23

I've installed successfully KB5000871 - it is listed here:

Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName
Security Update for Exchange Server 2013 Cumulative Update 23 (KB5000871)

And I can see it under Control Panel > Programs > Programs and Features > Installed Updates.

However in Exchange PowerShell shows version 15.0.1497.2 - while as far as I know - it should be 15.0.1497.12

[PS] C:\Windows\system32>Get-ExchangeServer | select AdminDisplayVersion

AdminDisplayVersion

    Thanks, Andy for a fast response.

    FileVersion is:

    Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo}
    
    ProductVersion   FileVersion      FileName
    --------------   -----------      --------
    15.00.1497.012   15.00.1497.012   C:\Program Files\Microsoft\Exchange Server\V15\bin\ExSetup.exe
    

    I've restarted this server after the installation of this patch. So - not sure why Exchange itself still shows .2 - also in WebGUI
