Thanks Adrian!

It is working for me as well with the insider preview build.

I had to add the following lines to the end of the config.txt on the Pi's SD card for the best display with my v1.0 Official Raspberry Pi display board. It defaulted to being upside down. This rotates it 180 degrees to show the right way again. You can edit the config.txt file if you just stick the SD card back into your computer. It will be in the root of the SD card. Or, you can leave the SD card in your pi, and connect to the file via a unc path, \\<your.pis.ip.address>\c$\efiesp\config.txt . (login with the Administrator/p@ssw0rd credentials unless you changed them). Anyhow, add the following two lines to the very bottom of the config.txt file then reboot the pi :

# Set Resolution and Rotation the screen for the Official Raspberry Pi Touch Display

lcd_rotate=2 # Rotate the display 180
