Change the on screen keyboard to extended mode

the registry entry for this is
HKCU\Software\Microsoft\TabletTip\1.7\ShowAuxPad
and the type of value is a REG_DWORD
setting this to 1 (decimal) will change to extended mode.
I needed to do this for a specific application that needed page up and page down functionality.
I used a group policy preference and it worked perfectly.

Win 7 Tablet – Show the on screen keyboard

I have had to do some SCCM Task sequence and Group policy work to make a Panasonic tablet play nicely with Windows 7. One setting that I found essential but that was poorly documented was how to show the on screen keyboard at login. Eventually with some digging and testing I found the setting:

HKLM|SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\ShowTabletKeyboard
I created a new OU  and an associated Group Policy for the Tablets and set the value of this to 1 using group policy preferences and happy days the on screen keyboard is ready to use at login.
