In the Creators Update it ignores the Appdata\Local\TileDataLayer what you have on the server and always uses the default layout under "C:\Users\Default\AppData\Local\Microsoft\Windows\Shell\DefaultLayouts.xml" or if you modified it, it uses "C:\Users\Default\AppData\Local\Microsoft\Windows\Shell\LayoutModification.xml" when you have a roaming profile on the server and logon to a new machine.
Maybe good to know if you want to use a LayoutModification.xml file you have to always use DesktopApplicationID instead of DesktopApplicationLinkPath otherwise the Start Tiles don't get displayed.
