自动排列图标reg设置

Windows 10 1703 Ent build - Auto arrange icon on desktop. (microsoft.com)

Hi, 

We can use GPP to deploy the registry key in your environment to make auto arrange work always:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Shell\Bags\1\Desktop

FFLAGS DWORD

1075839521 = Auto arrange icons = ON and Align icons to grid = OFF

or this value can also work for you: 

1075839525 = Auto arrange icons = ON and Align icons to grid = ON
