What’s stordiag.exe? Is it safe or a virus?

StorDiag.exe is a utility developed by Microsoft for analyzing Windows storage usage and diagnosing issues related to storage. It can help users identify and troubleshoot problems such as high storage usage, inefficient storage allocation, and disk performance issues.

The tool collects data related to storage configuration, disk usage, and logging information, which can then be used to generate detailed reports and recommendations for optimizing storage performance. StorDiag.exe is a valuable tool for users who want to better understand and manage their storage resources, and it can be particularly useful for diagnosing and resolving storage-related issues on Windows operating systems.

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.
