Userinit.exe is a key Windows Operating System process. It manages different startup sequences on computer startup. This process specifies the programs that Winlogon runs on user logon. By default, Winlogon runs userinit.exe, which runs logon scripts, re-establishes network connections, and then starts explorer.exe, the Windows shell. Userinit.exe is important for computer stability and should not be disabled or deleted. If you delete it, you will not be able to log into Windows.


The userinit.exe process is safe and disabling it can be dangerous, because programs on your computer need it to work correctly. Some other processes use the same file name.
