It's XP. Running in RDP mode. It's got IE6, and wants antivirus. Of course it's vulnerable to any and all gobs of stuff out there. But it's goal and intent is to allow Small shops to deploy Win7. If you need more security, get appv/medv/whateverv or other virtualization. It's not a security platform. It's a get the stupid 16 bit line of business app working platform.
