Your Windows might start properly but may take a really long time to boot. Microsoft has come up with a solution for this. To help administrators identify the source of startup performance problems, and to automatically fix some problems, they have introduced Windows Boot Performance Diagnostics.
Windows Boot Performance Diagnostics tool is included with Windows Vista, Windows 7, Windows 8.1 and Windows 10 operating systems. The Windows Boot Performance Diagnostics tool can be use to detect Windows Boot Performance problems and attempt to determine their root causes.
You will first have to activate it from the Group Policy Editor. To do so, type
gpedit.msc in Start Menu search box to open the Group Policy Editor.
Now navigate to
Computer configuration > Administrative Template > Systems > Troubleshooting and Diagnostics > Windows Boot Performance Diagnostics.
In the right panel, double-click
Configure Scenario Execution level.
You may see it set to “Not configured”. Select “Enabled”.
Now select Scenario Execution Level. From the drop-down menu select “
Detection and Troubleshooting Only” or “
Detection, Troubleshooting and Resolution”.
If you select “Detection and Troubleshooting only” then the Diagnostic Policy Service (DPS) will detect Windows Boot Performance problems and attempt to determine their root causes. These root causes will be logged to the
Applications and Services Logs | Microsoft | Windows | Diagnostics-Performance event log when detected, but no corrective action will be taken.
If you select “Detection, Troubleshooting and Resolution”, the DPS will detect Windows Boot Performance problems and indicate to the user that assisted resolution is available.
If you disable this policy setting, Windows will not be able to detect, troubleshoot or resolve any Windows Boot Performance problems that are handled by the DPS.
If you do not configure this policy setting, the DPS will enable Windows Boot Performance for resolution by default.
During a shutdown or restart, you may get to see this Shutdown Tracker window.
Make sure Diagnostic Policy Service is in the running state. When the service is stopped or disabled, diagnostic scenarios will not be executed.
The Group Policy Editor is not included with Windows Home editions. It’s only available in Pro, Education, Business, Ultimate and Enterprise editions.
