Windows 2012 R2 servers not rebooting after updates despite AUOptions set to 4 and AlwaysAutoRebootAtScheduledTime set to 1
hi, using gpos configure windows update options our servers. noticed major number of windows 2012 r2 servers not reboot after update installation, display 'we'll finish installing updates next time pc restarted.'
this expected behavior auoptions set 3, set 4:
c:\>reg query "hkey_local_machine\software\policies\microsoft\windows\windowsupdate\au" hkey_local_machine\software\policies\microsoft\windows\windowsupdate\au auoptions reg_dword 0x4 noautorebootwithloggedonusers reg_dword 0x0 noautoupdate reg_dword 0x0 scheduledinstallday reg_dword 0x1 scheduledinstalltime reg_dword 0x1 alwaysautorebootatscheduledtime reg_dword 0x1 autoinstallminorupdates reg_dword 0x1 detectionfrequencyenabled reg_dword 0x1 detectionfrequency reg_dword 0x4 rebootwarningtimeoutenabled reg_dword 0x1 rebootwarningtimeout reg_dword 0xa aupowermanagement reg_dword 0x1 reschedulewaittimeenabled reg_dword 0x1 reschedulewaittime reg_dword 0x1 includerecommendedupdates reg_dword 0x1 usewuserver reg_dword 0x1
but today (may 2nd) control panel still looks this:
interestingly, @ update installation time (2016-04-24 @ 01:02) event logged:
log name: system source: microsoft-windows-windowsupdateclient date: 2016-04-24 01:02:20 event id: 22 task category: automatic updates level: information keywords: reboot user: system computer: xxxx description: restart required: complete installation of following updates, computer restarted within 15 minutes: - update windows server 2012 r2 (kb3144474) - update windows server 2012 r2 (kb3146978) - update windows server 2012 r2 (kb3146601) - update windows server 2012 r2 (kb3145432) - update windows server 2012 r2 (kb3103709) - update windows server 2012 r2 (kb3146604) - update windows server 2012 r2 (kb3146627) - update windows server 2012 r2 (kb3134179) - update windows server 2012 r2 (kb3149157) - update windows server 2012 r2 (kb3145384) - update windows server 2012 r2 (kb3125424) - update windows server 2012 r2 (kb3144850) - update windows server 2012 r2 (kb3146751) - update windows server 2012 r2 (kb3103616)
but reboot did not occur.
as said, issue not limited machine, there many same issue. there missed? additional registry key required? additional logs investigate?
