What’s runonce.exe (Run Once Wrapper)? Is it safe or a virus?

Runonce.exe by Microsoft Windows is a program that runs once at the next startup of the computer to execute certain tasks or commands.

It's designed to help set up and configure the system for the first time after a major update or installation. The runonce.exe process allows the operating system to perform tasks such as installing drivers, configuring settings, or running specific scripts before the user gains access to the desktop.

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?
