Event ID 101 Windows Diagnostics Performance

Event ID 101 Windows Diagnostics Performance

Table of Contents

Applies To

Windows Server 2008, Windows 7

Cause

Event ID 101 indicates an application is taking longer than usual to start up, resulting in
boot time degradation caused by a system startup process.


Details

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.
