What’s NetworkSpeedTest.exe (NetworkSpeedTest)? Is it safe or a virus?

NetworkSpeedTest.exe is the executable for Microsoft's Network Speed Test app, developed by Microsoft Research.

This utility measures your internet connection's upload and download speeds, latency, jitter, and packet loss. It also logs test history and displays network details like SSID and connection type.

The app is designed for Windows 10 and 11 and is available for free. When running tests, it may collect anonymized network and device data to help Microsoft improve network quality and availability.

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.
