This is a Windows system installed file with Windows File Protection (WFP) enabled.

What is wininit.exe?

The Wininit file is an .ini file that lists all of the changes to be made to Windows when you restart the computer after installing a program. The Wininit.exe file is the program file that starts the .ini file. It can be run only when the computer restarts so that the changes can be made while Windows is not running.

Overview

wininit.exe executes as a process under the SYSTEM account with extensive privileges (the system and the administrator accounts have the same file privileges) typically within the context of its parent svchost.exe (Host Process for Windows Services by Microsoft Corporation). It has been configured with a firewall exception which allows both inbound and outbound network communication without being blocked. This version is installed on Windows 8 and is compiled as a 64 bit program.
