Steps based on [WayBack] How to turn off auto start on-screen-keyboard on Windows 7 64 bit? – Super User.
- Turn down the volume of your PC
- Run “Control Panel”
- Choose “Ease of Access”, then “Ease of Access Center”
- Click “Use the computer without a mouse or keyboard”
- If you forgot the sound settings, and they are at max: the narrative voice will probably deafen you
- Uncheck the “use on-screen keyboard” box
- Press “Apply” or “OK
- Close the “Control Panel”
I got in this situation when I selected the “On-Screen Keyboard” (often abbreviated to OSK; it is serviced by OSK.exe) on the logon screen in the “Ease of Access Center”. After that it would launch after each logon, even after I disabled it on the logon screen.
Back then I needed it because the VM ran on a Mac under Virtual Box which by default not only takes the left Command key, but also messes with some of the other left modifier keys.
The password for a new user I had to logon with needed the modifier keys, so it appears that the logon screen settings during the very first logon get copied to the user profile.
Turning them off on the logon screen does not copy them to the profile again:
