PROCEXP152.SYS: What Is It & What Does It Do?

.sys are essential system files that store hardware drivers, various system settings, and related Windows functions in Windows and DOS operating systems. One such file is PROCEXP152.SYS.

It is a system driver also known as a Process Explorer file and was developed by Microsoft as an essential part of Process Explorer. This system file falls under the Win64 DLL (Driver) file type category and was first created for Windows 10 operating system. 

What does PROCEXP152.SYS do? 

PROCEXP152.SYS is a crucial driver file of Windows OS which is a part of Process Explorer, the advanced process management tool that provides you information about which handles and DLLs processes are currently loaded and running. 

Despite process explorer being a well-known process management utility, XDR security solution and SentinelOne, an endpoint protection platform misinterprets its PROCEXP152.SYS driver to be vulnerable.
