The .sys is the file type and is a system driver.
It isn’t from Windows or XP, that is why I gave you the links to what it is associated with and why I asked how it comes to be running on boot. The association on that procezp100.sys file is from a tool that can check what processes are running on your system, it is called Process Explorer.
I can’t make the decision on Ignore or Delete as I don’t know anything about your system.
