Favorites issue

Hi

I implemented one GPO to add URL in all windows 7 users Favorites. I have added that two time and that was reflecting after implementing GPO. So for deleting the one URL from GPO i have made checked the setting (Delete existing favorites and links, if present) and select the URL and clicked apply.

But after checking these setting in GPO, all the local favorites has been deleted from all users profile and we are getting lots of end users call that favorites are missing.

Is there any way to recover or restore favorites which has been deleted from Group policy settings?
