Configuring Windows 10 defaults via Windows Autopilot using an MSI

Fantastic article! I really need to figure out how to use WiX Toolset. I was able to modify your Branding.ps1 script to include more modifications to HKLM and NTUSER.DAT

The OneDrive updater portion is brilliant. I'll be using that again!

Because I'm not familiar with WiX, I have to XCOPY files using a Win32 app, targeting the machine. This includes a logon script (mapped drives) and a folder containing the images for the desktop slideshow.
