I work for the government, Windows 7 is approved for testing use right now but they are worried about virtual XP.
We do a lot of remediation (checking for venerabilities in the OS) and they are concerned that the software we use to re-mediate and scan(Retina) will pick up the Windows XP OS in Windows 7 because of XP mode.
I tried to articulate my point, but had no data to back it up. Windows XP mode isnt a full OS as in it takes a portion of your hard drive to use for registry and installation programs like VMware. Rather the virtualization portion emlulates only what is needed for that particular program to run, its not a full OS that would take up a portion of the HDD and would be picked up on a scan.
Can anyone answer this? If so let me know where to find that info so I can prove my point.
