Windows 11 is a robust operating system, but system crashes, freeze-ups, and hardware bottlenecks can still happen. When your PC starts acting up, you do not need to guess what is wrong. Windows 11 includes a powerful suite of built-in diagnostic tools designed to pinpoint and resolve system errors.
Before diving into the tools, understand the stakes. Windows 11 is generally stable, but errors can stem from:
This tool provides a user-friendly "Stability Index" (1–10) and a timeline of critical failures. How to access : Search for "reliability" in the Start menu and select View reliability history What it shows : Red "X" icons for critical failures (like app or system crashes) and yellow triangles for 3.
