What’s WinSAT.exe (Windows System Assessment Tool)? Is it safe or a virus?

WinSAT.exe, or the Windows System Assessment Tool, is a command-line utility included in the Microsoft Windows operating system. It's designed to assess and report on the performance capabilities of a computer's hardware.

When executed, WinSAT.exe runs a series of tests on the system's CPU, memory, disk, and graphics performance, and generates a Windows Experience Index score that reflects the system's overall performance. The results and scores generated by WinSAT.exe are used by Windows to optimize system settings and prioritize resource allocation for different tasks and applications.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
