Windows 7's Virtual XP Mode a Support Nightmare?
CWmike writes "Microsoft's decision to let Windows 7 users run Windows XP applications in a virtual machine may have been necessary to convince people to upgrade, but it could also create support nightmares, analysts said today. Gartner analyst Michael Silver outlines the downsides. 'You'll have to support two versions of Windows,' he said. 'Each needs to be secured, antivirused, firewalled and patched. If a company has 10,000 PCs, that's 20,000 instances of Windows.' The other big problem Silver foresees: Making sure the software they run is compatible with Windows 7. 'This is a great Band-Aid, but companies need to heal their applications,' Silver said. 'They'll be doing themselves a disservice if, because of XPM, they're not making sure that all their apps support Windows 7.'"
...but didn't Apple successfully pull this off twice?
stop posting troll articles!! :@
This is exactly what we want them to do. Virtualize the deprecated, old stuff, and get it out of the main operating system. Move on from the cruft of yore and build in some sweet new fundamentals that break backwards compatibility. We've been crying for them to do this for forever, so let's encourage it. It might add a bit of a support burden, but if it gives us a better product overall, what's the big deal?
The need for a separate antivirus makes sense because the virtual machine is running a different operating environment with susceptibility to different viruses. A separate firewall does indeed seem superfluous.
I think overall, this is a better way of moving forward. Windows has been essentially crippled from several different perspectives for years because of their need to support backward-compatibility, even with broken interfaces or insecure models. Letting a significant portion of that flow into VMs of older operating systems for those customers who absolutely, positively can not get off their old apps is a good compromise. It allows them to start with a cleaner slate for the majority who has no such requirements.
I'm 100% sure that a competent IT dept that has no use for this feature will, unsurprisingly, NOT USE IT, saving themselves all the support hassles entirely.
And for those that DO need this feature, they know there's basically no other way and it's worth the extra support hassle because they know they will have people saying Application XYZ MUST work I don't care how.
I suspect this means that the old applications that have to work and only currently work on XP can now be moved forward and the IT dept can get everyone onto Windows 7. Once there, the devs of these applications will have Windows 7 rather than XP to test against/run with and they'll have an incentive to update their programs to just work on Windows 7 because, like Classic on Mac OS X, this mode will have just enough 'impedience' that programs will be updated to work on Windows 7 native; but they will work okay in the meantime.
That's the thing - this isn't seamless. It's going to be a little tricky to set up applications to run in the XP box rather than natively on Windows 7, even if launching them is easy.
The trick is "Just enough impedience to get people to update to 7 native while providing a path."
I see no reason for a second AV program, providing the VM's virtual drive is readable by the host operating system. If any kind of nasty program gets installed, it's going to have hit the file system at some point, and if the host's AV can plug in to that file system, it can suspend or terminate the VM.
