SCCM TP 1908 is out now and one cool feature that is worth noting is the ability to change the keyboard layout of a boot image in WinPE.
To avail of the new ability right click on a boot image and select the Customization tab.
In the Dropdown menu for Set default keyboard layout in WinPE, select a keyboard layout that corresponds to your needs and then click apply, you’ll be prompted to distribute the image to your distribution points.
Once done, you can see that the keyboard layout (amongst other things) has been applied to your boot image.
