Using the command as follows:
Import-StartLayout -LayoutPath "C:\Users\User\Desktop\Blank_Layout.xml" -MountPath "C:\"
Unfortunately does not change the current Start Menu layout. It creates a new file under C:\Users\Default\AppData\Local\Microsoft\Windows\Shell\LayoutModification.xml
, and it is blank.
I'm hoping that is because I intended the layout to be blank, I also had to grant permissions to that folder to run the command in the first place.
The information I used came from Technet, I do know that this can be pushed via GPO and added to an image, but that is not the intended goal for now.
