SCCM Requires a Reboot to Complete the Installation

SCCM Requires a Reboot to Complete the Installation. I never missed installing any of the Cumulative Updates of SCCM 2012 R2. It’s a routine that I install all the SCCM 2012 R2 CUs in at least 4-5 different environments.

SCCM Requires a Reboot to Complete the Installation – For me, it’s very normal to restart the server before starting the SCCM /ConfigMgr 2012 R2 CU installation (whenever the wizard prompts me to do so). 

But today, it was something different. During the ‘Prerequisite Check’, SCCM 2012 R2 CU4 didn’t ask me to restart the server. Download SCCM 2012 R2 CU4 from here (kb/3026739).

To my surprise, SCCM / ConfigMgr 2012 R2 CU4 asked for a reboot at the end of the installation wizard. The MSI log file (cm12-r2cu4-kb3026739-x64-enu.msi.log) provided some more details.

The reason for the restart mentioned in the SCCM ConfigMgr 2012 R2 CU4 MSI log file is “Reason for Restart: 1”. As per the MSI logging, If this property is present with a value of 1, then the Installer will require a reboot because it overwrote an in-use file.

    1. StaffI’ve updated 4 of my servers and only 1 prompted for reboot. So we can’t expect reboot every time after installing SCCM 2012 R2 CU4 on your SCCM site Servers.

    1. StaffWas that a question or statement. If question then as per my experience I would update all the site servers and site DB. All the site systems will get automatically updated to SCCM 2012 R2 CU4 once you install this on site server.

  1. Hi,

    was SCCM console opened during CU installation?

    Restart information
    You do not have to restart the computer after you apply this update.

    Note We recommend that you close the Configuration Manager Administrator Console and any associated applications such as the Remote Control Viewer or Status Message viewer before you install this update.

    You may be prompted to restart the computer that the Administrator Console update is being applied to if the Remote Control Viewer (CmRCViewer.exe) is being used during the update process.

    You can avoid restarting by closing the Remote Control Viewer before you install the update, or by adding the REBOOT=ReallySuppress parameter to the update installation properties. Be aware that this parameter is automatically added to packages that are created by the Cumulative Update installation.
