I get the following error message when I boot up my daughter's computer: "Could not load or run C:\Windows\system32\winlogin.exe.  Make sure the file exists on your computer or remove the reference to it in the registry."  I did a folder and file SEARCH, and confirmed that winlogin.exe is in the system32 folder.  I am RUNNING WinXP Home SP2 with all updates.  I am certain this problem is a result of my attempt to remove references to mirc, and IRC program which my grandson probably installed in error, which caused continuous windows explorer windows to pop up at logon.  The IRC icon was hidden on the system tray, and had no Uninstall routine.  I was unable to install from the Control Panel because it was running, and I when I attempted to EXIT the program from the hidden icon in the system tray, it would trigger numerous windows explorer windows.  I removed references to mirc and irc in the registry, but still could not uninstall the program.  Finally, I booted into Safe Mode and successfully removed the IRC program (which I should have done in the first place).  Now my dilema is how can I resolve the error message above.  I appreciate any help you can give me.Hey there!

there are a lot of commands U could use in Command prompt however they are a pain.

to make it simple boot into OS disk and perform OS REPAIR. Im sure it will fix the issue.If you are able to boot into safemode go to Start/Run and type in sfc /scannow and hit Enter...let it run til it finishes and re-boot.
