What’s tcui-app.exe? Is it safe or a virus?

The `tcui-app.exe` process, developed by Microsoft Corporation, is associated with the Trusted Platform Module (TPM) and manages device security-related features such as encryption, credential protection, and secure boot. It is typically part of Windows Security or Microsoft Defender functionality, specifically handling scenarios where user interaction is needed for security settings or authentication tasks. This executable ensures secure communication and authentication between the operating system and hardware-level security features, enhancing overall device protection. It is a legitimate system-associated component and should not be disabled or removed, as it plays a vital role in maintaining system security and functionality.

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.
