I'm not sure why autoruns is reporting it as a problem, but the file c:\windows\system32\userinit.exe
is required by windows. You are right about keeping this file! I suppose you could submit the file to a free online scanner
to be sure.
Anyways, for your reading pleasure, it looks like someone else had the same situation as you do - they ended up disabling it by mistake and heres what they did to back out of it:http://www.techsupportforum.com/microsoft-...e-problems.html
If you are the cautious type, you could run ERUNT
to backup your registry configuration before making changes to startup items. I have ERUNT run automatically on logon for my pc - it works great.
