After installing the latest updates my tablet boots to windows login but I cannot enter my password as I have no on screen keyboard. If I hit ease of access I get the menu but no response to any of the options.
If I go to startup menu and hit F11 I get error code 0x0000225 and it talks of using recovery media.
You could log in for now with a OTG adaptor and USB keyboard.
The F11 recovery option will not work since it was upgraded from Windows 8.1, that breaks the recovery partition. You could also do a fresh installation of Windows 10 using the downloadable install image from Microsoft.
