Export Windows 10 Start Menu Layout
To export the Start Menu layout in Windows 10, you must first configure it the way you want. Then, run this PowerShell command to generate the configuration XML:
Export-StartLayout -path C:\start-layout.xml
After you have the XML, you can deploy it via Group Policy. The policy you are looking for is Computer Configuration > Administrative Templates > Start Menu and Taskbar > Start Screen Layout. Enabled this policy and set the path to the layout XML file.
You can use a UNC path, but it’s normally better to have the file local. You can use the File preference of Group Policy to deliver the file to your devices.
