Windows 10 Autologon on Deployment

I normally deploy Windows version 1607 and just recently became acquainted with the post-1703 OOBE and Autologon settings regression.

The issue:
OOBE will wipe autologon settings, if they are implemented during the same boot as setupcomplete.cmd. This nullifies scripted/touchless Windows 10 deployment methods.

The solution:
Use setupcomplete.cmd and schtasks.exe to make a scheduled task that runs on the next start. Upon reboot, the scheduled task waits [an amount of time] before adding autologon settings, making a task to delete itself and reboot the computer, then running the task.

My improvements:
– Consolidate the solution implemented by others into one script/scheduledtask.
– Avoid unnecessarily long and inconsistent wait times.
– Designed to handle both windows 7 and windows 10 deployments.
– Use a secure method (as secure as possible with autologon)
