Recently I noticed that when you sysprep Windows 10 and use CopyProfile=TRUE in your unattend.xml, it will copy over the last used folders and recent files of the built-in admin.
In order to remove the Quick Access history, you will need to place a batch file inside the built-in admin’s %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder in Audit Mode before running Sysprep.
The batch file will need to have the following script to work:
@echo off Title Initial Setup echo Removing Quick Access History... del "%appdata%\microsoft\windows\recent\automaticdestinations\*" /q ping -n 3 127.0.0.1>nul echo Done ping -n 2 127.0.0.1>nul del %0
