I have a Dell Zbook 17 G5 laptop with nvme ssd i use for work that i am pulling my hair out to fix this issue i am having. After a fresh boot, if i restart or shutdown (possibly even just log off but i haven't test it), it will stay in the shutdown screen for 7-10 minutes before proceeding to turn off. If i was logged in for 10 minutes already, it will turn off/reboot normally in a couple of seconds.
I've disabled all non-microsoft services, removed the anti-virus, disabled windows defender, checked if page file delete policy is disabled, etc and can't find the issue.
Last resort i found this question and answer here: How can I identify the culprit of my slow Windows shutdown? and recorded 2 performance logs. One is "good" (quick restart since i was logged in for more than 10 minutes) and the other one is "bad" (slow restart since i rebooted as soon as i logged in). I can't seem to find a sure cause, but i am not familiar with the analyzer enough to know what is fishy.
That's why i uploaded both logs in hopes someone can please check them out: https://www.dropbox.com/s/76sowxabh8mndnp/windows_performance_logs.rar?dl=0
