    Hello all...

    We are troubleshooting an issue with SCCM where sometimes (most of the time) it uses wuauclt.exe to patch systems. On a few occasions we see that SCCM will use msiexec.exe to patch systems.

    Can someone explain why SCCM behaves this way?

    Thanks,

    Jeff

    Hello Jeff,
     
    Wuauclt.exe is the AutoUpdate Client of Windows Update and is used to check for available updates. When SCCM deploy updates to the clients, client system call the WUA to install them. 
     
    Msiexec.exe belongs to the Windows Installer Component and is used to install MSI (Windows Installer package) and MSP (Windows Installer patch) packages, While most of Windows Update packages are MSU or CAB.
     
    Hope my answer could help you and look forward to your feedback.
     
    Best Regards,
    Ray
