Anyway, this worked for me - regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl
add DWORD key named ConvertibleSlateMode
add value 1
No more File Explorer checkboxes, no more virtual keyboard.
You are my hero! I have a Wacom MobileStuido tablet that I prefer to use as a laptop. Under Windows 10, this wasn't a problem. But I finally bit the bullet and installed 11. 11, with no regards to my wishes, decided that since there is a touch screen and no attached keyboard, that CLEARLY I should be using this as a tablet.
Zero regard for the end user's wishes. Thanks, MS...
But thank YOU, Dragan, for restoring the actual functionality of my computer.
