I use SCCM 2012 MDT task sequences for majority of my images, and while the task sequence would eventually complete this issue added a considerable amount of time to the process.
One issue I experienced is images hanging on a “Just a moment…” screen for anywhere from 15 minutes to over an hour: Since the release of Windows 10, there have been a few new challenges arise when capturing and applying images. Successfully Tested On: Microsoft System Center Configuration Manager versions 2012 - 1903, Windows 10 Enterprise versions 1507 - 1903, Windows 10 Long-Term Servicing Branch (LTSB) versions 1507 & 1607 I write about the newer supported answer file in the article Use Unattend.xml to Skip Windows 10 OOBE during an SCCM Task Sequence. EDIT: While this method still works, it has officially been depreciated by Microsoft.
