There are many benefits to running Windows XP in a virtual desktop environment. For one, it makes deploying new images much easier and faster than having to update every desktop. Also it helps to control license usage. But does it provide any security benefits, since there's fewer images that need to be protected by antivirus, antimalware, and group policy permissions? I'm trying to build a business case for virtualizing our desktops and every bit of ammunition I get could prove helpful.
