Change Desktop icon size with Group Policy

In almost all VDI engagements, I would advise against statically setting the default icon size, because more often than not, the desktops will be presented on a number of screen sizes, resolutions, orientations and DPI. Instead, I suggest training the users how to adjust the icon sizes to their liking, 

1. [Ctrl] + [Scroll Mouse Up/Down]
2. [Ctrl] + [Shift] + [1/2/3/4/5/6/7/8] (Use the upper row of the main keyboard, not the Number Pad)

If a Group Policy is required, follow the steps below:

Using a combination of the manual sizing methods above, create a view that meets your requirements.

1. Create a per-user policy preference and import the following values from the path:

• HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Shell\Bags\1\Desktop:
• IconSize (DWORD)
• Mode (DWORD)
• LogicalViewMode (DWORD)
