2. Rename the script from .exe to .scr.
3. Copy the script to C:\Windows\System32\
4. In C:\Windows\System32\ Right-click on the script scr & select install.
5. Close the script when it runs.
6. In Screen Saver Settings check On resume, display logon screen.
7. Close Screen Saver Settings and wait for screen saver to start.
8. Click InetGet Input.
9. Error 0xc0000142 should be displayed.

I have tested with Vista / Windows 7 / IE7 / IE8 / AutoIt 3.3.0.0 / AutoIt 3.3.1.1 all fail.
It does not error on Windows XP.
Stumbled across this while implamenting automatic update functionality into a screen saver.
The ""Screen-saver"" desktop is created only when ""On resume, display logon screen"" is checked.
