Good addition. I think I might write a PowerShell scripting tut next, it's a powerful tool.
BTW, one practical way to make it really automatic without UAC is to boot to Audit Mode (install Windows normally, when it arrives to "Sign in to your MS Account" page after last reboot, press CTRL+SHIFT+F3). Do your customizations in Audit Mode, including app install with OneGet, then end with sysprep /generalize /oobe /reboot /unattend:Z:\YourAnswerFile.xml
The answer file only needs to contain the CopyProfile tags:
Installation picks now up where you left it with entering Audit Mode and finalizes the install. Doing it this way has two benefits: first, the apps will be installed for all users as they are copied to Default Profile, and second as the Audit Mode uses the built-in admin account there's no UAC, the rights are granted automatically whatever you install.

Only problem is that sysprep is "broken" in build 9926 (see my warning about this), hopefully MS get it fixed in the next build.
