Server 2012 R2 restarted automatically by windows update during working hours RRS feed

  • Question

  • Hello

    Our 1 Windows 2012 R2 VM suddenly restarted itself during working hours (10.30 AM), because it automagically installed updates (all june updates: KB4503259, KB4503276, KB45032), ignoring GPO. Noone clicked the "Install updates" button.

    GPO is configured like this (download updates, but don't install them, until Administrator doesn't click the magic button):

    • Configure automatic updating: 3 - Auto download and notify for install
    • Install during automatic maintenance: Disabled
    • Scheduled install day: 0 - Every day
    • Scheduled install time: 04:00

    Info from event log

    Restart Required: To complete the installation of the following updates, the computer will be restarted within 15 minutes:

    Is it a new update policy on Windows Servers (to force update system, no matter what, as on Windows 10's) or some bug in the update? Or am I missing something important?

  • Hello,

    I've enabled NoAutoRebootWithLoggedOnUsers policy - but I have question about it.

    What will happen, when administrator RDP session is in "disconnected" state?

    And 2nd question - what is wrong with the scheduled install time, as it's configured to do at 4AM, but the updates were automatically installed at 10AM?

  • Hi,

    Thank you for your feedback.

    When administrator RDP session is in 'disconnected' state, the system may restarted automatically.

    Make sure the time (UTC or not) is correct.

  • Time is 100% correct. SO how fully prevent automatic restart? I want to have full control of it, and don't want unexpected system restart during working hours.

  • The same issue happened again today...System automatically restarted at 10.30 AM. Restarted... because one update was automatically installed and the 15 minutes indicator has popped out.
