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.'"

      Mac OS is a niche market. In the Windows market, reality has a way of kicking you in the balls. Yes, this will be a support nightmare but we simply cannot write of the biggest heap of legacy software ever. That would be the true nightmare, no correct support for older apps. And by older I mean everything tailored for XP, either 1 or 7 years ago.

      Actually, Windows has a way of kicking you in the balls. How would running XP in a virtual machine be any different from the usual windows experience?

      I think this is the smartest move Microsoft has done in a long time. They need to relegate the backwards compatibility to a virtual machine, and make the next Windows OS much leaner and secure.

      I agree with the GP that Apple had little problems with this and their market is of sufficient size to assume that Microsoft would fare just as well.

      No, it was an actual 68LC040 emulator in software.

      In fact, large chunks of the System were still written in 68040 code for a long time. So new releases of the OS would actually run faster and faster as that code was replaced with native versions.

    The better it works the easier it will be to support. Also why does the XP instance have to have its own antivirus and firewall? I don't understand why the windows 7 (Magnificent 7? Windows Magnifica!) firewall and antivirus won't be sufficient for the virtual XP machine inside.

      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 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.

      It gets even better. If they ship an XP compatibility layer in 7 it tells everyone that XP apps will be a supported option for the lifetime of Windows 7. And if XP is kept alive in this way, ya you are probably right that patches for XP itself will probably be continued for quite some time, especially since they are going to be selling newly licensed copies at least as late as this Xmas.

      However it is the follow on effects of a promise that XP will be a viable platform to run applications in for at least the next 5-7 years. It makes XP the safe choice of API to write new code to. An XP compatible application will run on XP, Windows 7 and via CodeWeavers increasingly effective efforts (as the XP target has remainied basically stable for years) it means an XP application can run at native speed on Mac and Linux. And it doesn't take that much effort to write XP apps that will run on 7 anyway without needing the emulation layer so 7 compatible XP code is going to be a more universal binary than Java ever achieved in the real world.

      If Microsoft isn't careful with this XP on 7 plan they could Warp themselves.

    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.

    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.

  8. IT depts that don't need it ain't going to use it! by Anonymous Coward · · Score: 5, Insightful

    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."

    This is sad, just another example of how the wheels are coming off the cart while careening down another blind alley. I was at a trade show last month, and the visit to the Microsoft booth was surreal. The first kiosk was for Windows 7 and a smiling young man touting the virtues of this beta software. When I mentioned that I was having trouble running Vista on a 3.2GHz P4 with 4GB RAM, a 512MB ATI video card with DX10.1, and a terabyte HDD, he scoffed and said that nobody at Microsoft was running Vista, not even the developers. He gave me a DVD of beta 7 and told me that even as a beta, Windows 7 was "so much better than Vista." I accepted his disc (which expires on August 1), and went to the Windows Mobile (WM).

    This kiosk had a good looking young man who was part of the product management group for WM 6.5 and very knowledgeable about the product. When I told him that I was a WM developer, he listened attentively as I explained my frustration in trying to program the WM6 smartphone camera to work. His smile faded as he explained that Microsoft had failed to thoroughly test the OEMs for WM5, WM6 and WM6.1. As a result, the DirectShow APIs for many phones were not fully/correctly implemented. He showed me a web page - http://studierstube.icg.tu-graz.ac.at/handheld_ar/camera_phones.php - that explained the problem phones. Then I asked, "will this be fixed in the coming 6.5 release?" He shook his head and replied, "no, not until WM7." I thanked him for his candor and moved onto Live Search.

    At Live Search, a bright young man was touting the performance of their latest version and let me test it against Google, where it seemed to respond comparably. He talked about how his group was trying to get other parts of Microsoft to use their Live Search instead of their own, "an uphill battle." At that moment, another person walked up and asked a question, prompting him to pull out his iPhone. I reached out with my WM phone and joked, "wouldn't it be more politically correct to show this?" He responded, "oh, no. Most of my friends at work have iPhones. It's OK."

    The problems documented by Daniel Wagner's web page (above) and unmentioned on microsoft.com or msdn.com cost us three months of development time. I should have suspected; mea culpa. Our application now runs on iPhone, and we are not looking back.

    BTW, the Microsoft coffee table looks like a giant iPhone.

    You don't have to be a genius to figure it out. OSX doesn't have the same protections. It doesn't even have the protections Windows XP SP2 has and that came out 5 years ago.

    If you don't believe me, just get the opinion of any of the top security researchers on the security of OSX compared to XP/Vista.

    The reason why OSX is not exploited as much as windows is it is the equivalent of a house in a small village. Hardly anyone would bother break in even if the door is unlocked.
