SCCM updates deployed before Deadline

Hi Experts ,
i know its a common question but i have not found a clear answer till now , some of the PCs are receiving the updates before the deadline is reached . no MW available and the option on software center ( automatically install required software only outside of the specified business hours ) is not ticked . for exp i had the deployment of the updates available at 10 and deadline on 15 , they started installing the updates since the 10 . what else can i check ?

    The only possibilities here are that the user initiated the update installation or the deployment is set to use UTC and thus there's a mismatch between your expectations and the time they should install. Also note that maintenance windows are 100% irrelevant here as they never cause deployment enforcement.

    To clarify here as well, how do you know the updates installed early?

    hello , i got a message from a user asking me about the update ... i also check updatedeployment.log time and windowsupdate.log ... the user didnt initiate the update as many other got the update deployed , i checked the deployment in the monitoring pane from sccm also and the deployment is client time ... i know its weird but i dont know where else to troubleshoot this behavior .

    Then you should open a support case as there are no other by design behaviors in ConfigMgr to do this.

    Thank you for posting in Microsoft Q&A forum.
    You may check the Scheduler.log in client to find a message like below to see when did the installation triggered?
