What is WinSAT?
WinSAT (Windows System Assessment Tool) is a built-in module in Windows that measures various performance characteristics and capabilities of the hardware it is running on.

To run a full formal assessment, type "winsat formal" and press Enter. The process usually takes 2-5 minutes.

3. Understand the Scores
Scores range from 1.0 to 9.9. Your overall score is determined by the lowest sub-score (the bottleneck), not an average.
Common Questions
Why did WinSAT disappear from the UI?
Microsoft removed the visual interface in Windows 8.1 to simplify the Control Panel, but the engine still exists for system optimization.
What is a "good" score?
For modern Windows 11 usage, a score above 8.0 is excellent. Scores between 6.0 and 7.9 are solid for office and light gaming. Below 5.0 often indicates a mechanical hard drive or very old CPU.
Does WinSAT damage my hardware?
No. It puts a high load on your components for a few minutes to measure peak performance, similar to a demanding video game.
How often should I run a test?
You should run it after installing new hardware (RAM, SSD, GPU) or after a fresh Windows installation to ensure everything is configured correctly.
Why is my score 1.0 or 0.0?
This usually happens if a driver is missing (especially for graphics) or if the test was interrupted. Try running the command again as Administrator.
