What’s tapinstall.exe (Windows Setup API)? Is it safe or a virus?

Tapinstall.exe, associated with OpenVPN Technologies, Inc., is a command-line tool that utilizes the Windows Setup API to manage network device drivers, particularly for virtual network interfaces like TAP drivers used by VPNs. TAP drivers enable communication between the operating system and the VPN's virtual network adapter, facilitating encrypted network traffic. Tapinstall.exe is typically used during the installation or update of OpenVPN to add, remove, or configure TAP drivers programmatically. It is safe when obtained from a legitimate source and is essential for establishing secure VPN connections. Misuse or tampering, however, could lead to driver-related issues on your system.

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.
