What’s micmute.exe? Is it safe or a virus?

micmute.exe is a Lenovo utility that manages the microphone mute function on Lenovo laptops, particularly ThinkPad models. It's part of the On Screen Display software suite, which provides visual feedback when hardware buttons are pressed, such as volume or brightness controls. In this case, when the microphone mute button is pressed, an icon appears on the screen indicating the current mute status of the microphone.

You might have micmute.exe on your machine if you're using a Lenovo laptop that includes this feature. It's typically installed as part of the Lenovo Hotkey Features Integration package, which enables the function keys (like F4) to control hardware features.​

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.
