WinLogon Process – WINLOGIN USERINIT
Userinit.exe or "winlogin userinit" is a process in Windows NT 3.x or later, Windows 2000, and Windows XP.
It specifies the programs that Winlogon runs when a user logs on.
By default, Winlogon runs Userinit.exe, which runs logon scripts,
reestablishes network connections, and then starts Explorer.exe, the Windows user
interface. This file can be configured to add, remove, or substitute programs.
We'd recommend against removal.
