I created a generic Windows 10 reference image in Audit mode, captured it through MDT, and have redeployed it to another PC after setting CopyProfile=True in the Unattend.xml. This all works as expected, except the Desktop shortcut in "Quick access" and "Frequent folders". This shortcut points to the original Administrator's desktop folder for any new user that logs in. All other folders are appropriately mapped.
It also appears Cortana is not working either.
Has anybody else seen this or can confirm?
