What’s setup.exe (Windows Installation and Setup)? Is it safe or a virus?

Setup.exe is an executable file commonly used by Microsoft Windows to initiate installation or setup processes for various software programs or drivers.

When a user initiates the setup.exe file, it launches a wizard that guides the user through the installation process, prompting them to select installation options, agree to terms and conditions, and choose a destination for the installation. The setup.exe file then copies necessary files to the designated location, sets up registry entries, and creates shortcuts for the newly installed program. This process allows for a standardized and user-friendly installation experience for Windows users.

In this case, this setup.exe is specifically for setting up the Windows OS itself. If you're seeing setup.exe running on your PC, you should check who signed the app to make sure it's safe. If it's signed by Microsoft itself, it should be safe to have running on your PC.

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.
