Many commercially made brand name systems have what would be on the oem Windows disk on the hard drive instead of giving you a disk.
Your problem is most likely the result of a virus.
You need to repair Windows or reload Windows completely as far as I can see.
Click ctrl/alt/delete and see if it brings up the task manager, and if it does see if you can start explorer.exe (explorer - not Internet Explorer).
What brand of computer and what operating system do you have and have you looked on your manufacturer's support site for instructions?
USERINIT is the program which Winlogon runs immediately after a user successfully logs onto a Windows NT4/2000/XP/2003 PC. USERINIT runs logon scripts, re-establishes network connections, and then starts Explorer.exe, the Windows user interface (the START button, etc..).
An integral part of the operating system – leave well alone. Depending on what runs at logon on your PC and on the network (if you are connected to one), and also depending on the speed of your PC, USERINIT will normally stay in your Task List for only 30 seconds to 3 minutes, and will then terminate and disappear off the Task List. If you experience USERINIT errors on logon on a Windows 2000 PC/Server, make sure you have installed at least Service Pack 4 for Windows 2000. If you experience errors in other circumstances, then check your PC for viruses.http://www.answersthatwork.com/Tasklist_pages/tasklist_u.htm
