Over the course of the past few releases, several features have been added to the Deployment Solution to support remote imaging using Cloud Enabled Management (CEM).
One of the primary remaining challenges to support remote imaging for users working from home is that the Windows ADK does not support the use of Wi-Fi adapters in WinPE. Given that most home users no longer have ethernet connections available, this means that home users would be unable to connect to a PXE server over the Internet when using CEM.
For a workaround that may enable you to overcome this limitation, see KB Article 268140.
