What’s intel_cst_helper_service.exe (Intel.Cst.Ipc.HelperService)? Is it safe or a virus?

The file intel_cst_helper_service.exe, published by Microsoft Windows Hardware Compatibility Publisher, is a component of Intel's Context Sensing Technology (CST). This technology enables features like "Wake on Approach" and "Walk Away Lock" by detecting user presence, enhancing device functionality through environmental data such as location, proximity, and motion.

You might have this executable on your machine if your system includes Intel hardware that supports CST. It's typically installed as part of the Intel Dynamic Platform and Thermal Framework or similar Intel software packages. While researching online I found that Dell hardware can sometimes have this Intel proximity feature.

The file is usually located in the Windows system directories and is signed by Intel Corporation.

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.
