Got an error while using logonui.exe

Asked By 0 points N/A Posted on -


I was using Win XP and intermittently got this error message, see screenshot below.  I thought that it was a virus as some articles in the web suggested so I tried scanning manually my PC with antivirus software. Well, it turned out that my PC was clean.  Anyway, any help for the resolution to get rid of this error message is greatly appreciated.

logonui.exe – Application Error

The instruction at “0x10004250” referenced memory at “0x10004250”. The memory could not be “read”.

Click on OK to terminate the program

Click on CANCEL to debug the program

4-      If the problem still persist, run any registry cleaner tool like ccleaner( or  RegInout (

Hi there user:

This is an attack to your operating system. Install the Windows CD and then Enter to boot from the CD. Click R, and then type the user password, enter. Type the ‘copy userinit.exe wsaupdater.exe, and then reboot the system. Start, Run, type ‘regedit’. Modify C:WindowsSystem32wsaupdater.exe to C:WindowsSystem32userinit.exe.
