The built-in Windows 10 reliability monitor is an often overlooked troubleshooting gem. It’s actually a specialized subset of Windows’ general-purpose performance monitoring tool (perfmon.exe). But because Reliability Monitor focuses on and tracks a limited set of errors and changes on Windows workstations, it offers immediate value and diagnostic information to administrators and power users trying to navigate through crashes, failures, hiccups and more.
Launching Reliability Monitor
There are many ways to access Reliability Monitor in Windows 10. In the search box, if you type connected you’ll usually see an entry that says “Show reliability history” in response. Clicking on it will open the Reliability Monitor window. You can also click the Start button, then the Settings icon and search for connected to get the same menu option as shown in Figure 1.
If you want to navigate to the location of this item in the Control Panel hierarchy, here is the sequence of selections involved: Start > Control Panel > Security and maintenance > View reliability history (under Maintenance).
My favorite way to launch Reliability Monitor, after occasional difficulties with Windows Search, is to type perfmon /rel in the search box or the command line.
