Q - question

Windows shutdown is very slow.

A - answer Symptom: When you power-off (shutdown) your operating system, it takes minutes to complete the shutdown.

The is usually caused by a registry setting or by problems with terminating a system service or a driver.

First check the security setting for clearing Windows paging file - this setting controls whether Windows overwrite the paging file with zeroes on shutdown. If you do not need such security level, switch off this option in the Registry with REGEDIT: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management - set the ClearPageFileAtShutdown item to 0 (and restart your system).

Another cause of such delays can by terminating network-oriented services (SQL, IIS...), antiviruses or some network drivers (e.g. Dell WLAN).
