What’s PowerShell Installer.exe (Store Installer)? Is it safe or a virus?

PowerShell Installer.exe by Microsoft Corporation, under the description "Store Installer," is associated with downloading and installing PowerShell from the Microsoft Store. PowerShell is a cross-platform task automation framework that integrates a command-line shell with scripting capabilities. The executable simplifies deployment by handling the installation process directly, managing dependencies, and ensuring the latest version of PowerShell is installed. This approach reduces complexity compared to manual installations. Typically, it is used for environments where applications are distributed through the Microsoft Store, ensuring users can easily obtain and update PowerShell in a standardized manner across Windows 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.
