Hi,

I want to run Onscreen keyboard when my logonscreen apears. So I wouldn't need the keyboard to login but can actually click on the letters to login.

I already tried in the registry through HKEY_USERS\.DEFAULT\Control Panel\Desktop\SCRNSAVE.EXE changed to osk.exe.

Then the onscreen keyboard start, but the background is black, so it runs as if a screensaver.

I actually want to use it...

In Vista there is a small icon in the left corner that open the OSK.
In XP, Press the Windows key + U.

That should get you sorted out.
