I use the w10 onscreen keyboard on my desktop pc because of disability & would very much like to use the osk at the initial startup so I can access the bios prior to boot & login ... thanks...
thanks for quick reply ...I don't want to use osk to run bios , I need to access bios prior to login ... eg F8 at startup ... Once in bios i can change settings etc with inbuilt bios tools ...
You might want to consider entering the BIOS from the Settings app instead which you should be able to do by tapping on the screen and without using the keyboard.
It can be done from Settings app > Update and Security > Recovery > Advanced Startup > Restart Now > Troubleshoot > Advanced Options > UEFI Firmware Settings.
