Wininit.exe It is an essential system for Windows. Its role is to perform in background some of the most important services/programs, like Service Central Manager (SCM), Local Security Authority Subsystem (LSASS) sau Local Session Manager (LSM), without which the system is not operable. That is why the completion or deactivation of this process is not recommended.
Winnit.exe It's a illegitimate process, malware, spread with the help of VIRUS of type worm W32/Rbot-AOM.
