While occasional degradation is normal due to software or hardware device driver updates, if you determine that a particular device or application event is being logged on a regular basis or results in a continuation of boot time degradation, chances are that there is a problem.  Check with your hardware or software provider to obtain updated device drivers or software.   The Event Viewer in Windows Server 2008 and Windows 7 includes a new category of event logs called Applications and Services Logs, which includes a host of Windows Performance Diagnostic subcategories which track information such as boot time, standby/hibernate and system shutdown.  The task category of boot performance spans the events detailed below.
