performance - Long shutdown times in Windows 7




I'm experiencing long shutdown times in Windows 7 Professional on newly built machines. After joining to a domain, they take over ten minutes to shut down. There is almost no software installed besides VNC and Office 2010. I ran a shutdown trace with Windows Performance Recorder and generated a graph of what's running during these long shutdowns. Most of the shutdown processes occur within the first minute or so and then wininit.exe (blue) and System (orange).



Shutdown analysis



So how do I go about reducing shutdown times in this scenario?


Answer



look at the summary of the disk graph. I can see you have a lot of disk IO.



Maybe you clear the pagefile at shutdown.




To check it, open regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management, locate the value ClearPageFileAtShutdown and make sure the value is set to 0.



This can cause such a slowdowns.
