Hi, folks,
What is Windows XP Mode:
Windows XP Mode is basically Virtual PC running Windows XP in a
pre-built virtual machine (VM) that you download free from Microsoft,
complete with license. Virtual PC only runs on Windows 7 Professional,
Enterprise, or Ultimate, and the computer must have the virtual
emulation hardware features that Virtual PC needs. Shortcuts on the XP
Public Start menu are sutomatically copied to the Windows 7 Start
menu, and adjustments are automatically made behind the scenes so that
the Windows XP Mode applications can work with documents on the
Windows 7 desktop or Documents folder. For example, when you tell
such an application that you want to look at the desktop, you actually
see the Windows 7 desktop, not the XP desktop.
What to expect:
Once it is set up and configured, applications installed in Windows XP
Mode are pretty much seamless with Windows 7; they look like just
another application, and they appear on the Windows 7 Start menu,
although sometimes you have to do some tinkering to get them to show
up. The first time after you log on to Windows 7, there is a delay as
the virtual machine is started up, but after that, applications pop up
instantly, until the next time you log on. If you have the Windows 7
and Windows XP appearance set to look similar or the same, you cannot
easily, if at all, tell whether an application is running under
Windows XP or under Windows 7.
How to set it up:
Go to the Microsoft Virtual PC download page at
http://www.microsoft.com/windows/virtual-pc/download.aspx to download
both Windows XP Mode and Virtual PC. You should install Windows XP
Mode first, then Virtual PC. Once you have both installed, and have
restarted te computer, you should find Windows XP Mode listed under
Virtual PC in your Start menu, and you can then start Windows XP and
configure it and install your application(s).
Caveats:
Applications running in Windows XP Mode automatically have access to
the same drives that Windows 7 does, and use the Windows 7 network
(internet) connection, so it should not be considered a protection
against malicious software. Windows XP also needs all of the updates
and protection (including antiviru software) that it would need if it
were running on real hardware, although since all of the data appears
to go through Windows 7, it's probably not quite as insecure as it
would be otherwise. Nevertheless, there is always the possibility that
a security flaw in Windows XP can make the Windows 7 system easier to
attack.
Gamers should be aware that DirectX is not supported under Virtual PC,
so older games that don't run under Windows 7 will need a dual-boot
system.
Conclusion:
Although Windows XP Mode could be easier to install (such as included
with Virtual PC or preinstalled in Windows 7), and installing
applications in Windows XP Mode could also be made transparent (for
instance, right-clicking on the installer and selecting "Install in
Windows XP Mode" would be nice), it seems pretty likely, as others
have commented, that this is the future of backwards compatibility, to
make it easier for old technologies to be dropped from future versions
of Windows, or even to transition to something which bears little
resemblance to modern Windows.

Good advice is like good paint- it only works if applied.
