What’s PolicyRulesFileBuilder.exe (Utility program used by Policy Analyzer)? Is it safe or a virus?

PolicyRulesFileBuilder.exe is a utility program created by Microsoft Corporation as part of the Policy Analyzer toolset. Its primary function is to assist in the creation and management of Policy Rules (.PolicyRules files) that are used to analyze and compare Group Policy settings within Windows environments. The tool allows administrators to consolidate and evaluate Group Policies by generating rule files for use with Policy Analyzer, making it easier to identify conflicts or inconsistencies in policy configurations. It streamlines the process of creating these rule files for better policy auditing and compliance management, enhancing system policy oversight.

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.
