What’s MBR2GPT.EXE? Is it safe or a virus?

MBR2GPT.EXE is a command-line tool provided by Microsoft Windows that allows users to convert a disk from the Master Boot Record (MBR) to the GUID Partition Table (GPT) partition style without data loss.

Microsoft writes on their official website that:

"You can use MBR2GPT to:

Convert any attached MBR-formatted system disk to the GPT partition format. You can't use the tool to convert non-system disks from MBR to GPT.
Convert an MBR disk with BitLocker-encrypted volumes as long as protection is suspended. To resume BitLocker after conversion, you'll need to delete the existing protectors and recreate them.
Convert an operating system disk from MBR to GPT using Microsoft Configuration Manager or Microsoft Deployment Toolkit (MDT)."

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.
