Hello, reading through this thread i believe i found place where can i get some help or info at least. I ran into strange issue: on new and freshly installed and updated machines (win7pro64sp1) after first reboot and joining domain the pc's start to have problem with really slow shutting down,and logging off. Sometimes it shuts down immediately, but in most cases it takes 5 or even 10 minutes. Clearing page file was disabled and wait to kill service set to 2000, but no effect, machine hardware vary but all have ivy bridge cpu i3/i5, 120GB ssd drive and 8GB of 1600 Mhz RAM. I looked in event viewer and noticed number of events 6005 stating that:The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (EndShell), and 6006: The winlogon notification subscriber <GPClient> took 524 second(s) to handle the notification event (End Shell). I did:xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+DRIVERS+CSWITCH+POWER -resultPath c:\shutdowntraceand:xperf /tti -i shutdown9.etl -o shutdown9_info.xml -a shutdown. I spent two days trying to figure out, but no succes...so, please help,i need some magic.
