Analyzing Slow Startup and Shutdown using Event Viewer

If your computer takes a long time to boot up or shut down, you can use Event Viewer to perform a prelimiary analysis of what services are causing the most delay.  To do this, open Event Viewer and expand the following log:

Applications And Services Logs\Microsoft\Windows\Diagnostics-Performance\Operational

Right-click on this log and select Filter Current Log.

To filter for boot events, type 100-199 in the Event IDs field and click OK.

To filter for shutdown events, type 200-299 in the same field and click OK.

Here is an example of a service causing delayed shutdown:
