Try out Windows Autopilot white glove pre-provisioning

Hi @Michael Niehaus - thank you for your great write-ups.

I found a nuance with "Pre-Provisioning" in that none of my devices were showing the "Select Region" screen in OOBE, so I was unable to initiate the WINKEY sequence to bring up the pre-provisioning menu.  Finally I traced it back to my "Autopilot Deployment Profile", which - by default - configures the "Language (Region)" selection to "Operating system default".  This means that the OOBE will never display the region page, and you can never initiate pre-provisioning".  Once I changed that setting to "User select", the OOBE now displays the region page and I use the WINKEY press to bring up the menu.  I have not found this "gotcha" documented anywhere, so perhaps this can be added to the MSFT Docs.
