windows 7 modify explorer taskbar target

Hi all,

for users in a particular OU, I'd like to change the target of the taskbar explorer icon so that it shows "computer" instead of "libraries". I found that I could replace the target with this:

"%SystemRoot%\explorer.exe /e,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}"

and I should use the "replace" feature in the user's GPO shortcut preference.

what would be the correct procedure to achieve this?

thanks
