What’s Clockres64.exe (Clock resolution display utility)? Is it safe or a virus?

Clockres64.exe by Microsoft Corporation is a utility that displays the clock resolution settings of the system processor.

It shows the minimum, maximum, and current timer resolution, which directly affects how frequently the system clock interrupts processes to maintain time accuracy.

This information is useful for developers and advanced users who require precise control or monitoring of system timing, particularly in performance-sensitive applications like gaming, multimedia, or time-critical software.

By understanding and potentially tweaking the clock resolution, users can optimize system behavior and responsiveness for particular tasks. The tool provides insights but does not itself modify the timer settings.

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?
