Windows 7 Compatibility Issues May Mar Enterprise Adoption

eWEEK Labs' early tests of Windows 7 RC 1 show that the operating system installs and runs quickly and efficiently; is highly polished for this stage of development; already supports a wide array of hardware; and is obviously rich with security, connectivity and usability features when compared with either Windows Vista or XP. However, Microsoft's method for dealing with application compatibility--Windows XP Mode for Windows 7, or XPM--leaves something to be desired.

Microsoft officials proudly proclaim that the Release Candidate landmark of the Windows 7 development cycle represents a good time for businesses to start evaluating the new operating system in a production environment. While the code made available to this point seems strong enough to warrant this level of in-depth appraisal, I suspect IT implementers will quickly find too many questions unanswered to gain a firm grip on the role the new operating system can play in the enterprise-or if it has a role at all in the near term.

In my few days with the new version, I've found that the release candidate (Build 7100, available now to MSDN and TechNet subscribers and to the public on May 5) installs and runs quickly and efficiently; is highly polished for this stage of development; already supports a wide array of hardware; and is obviously rich with security, connectivity and usability features when compared with either Windows Vista or XP. 

But with the issues of application compatibility and licensing still not addressed in a manner companies can test, and with Windows 7's deep ties to the forthcoming Windows Server 2008 R2 to consider  (not to mention the moribund economy), potential implementers may find it difficult to find the value in the new OS, despite its obvious improvements.

Application compatibility, or lack thereof, was one of the torpedoes that sank Windows Vista-too many users and organizations found that operating system's security implementations broke mission-critical legacy applications or devices. As Windows 7 is built with the same security fundamentals in mind (including User Account Control, Address Space Layout Randomization and Kernel Patch Protection), Microsoft had to address the issue head-on with the new OS, to ensure customers a seamless transition to the new platform.

The announced solution-Windows XP Mode for Windows 7, or XPM-runs a virtualized instance of XP Service Pack 3 within Windows 7. Customers licensed for the right version of Windows 7 (Professional, Enterprise or Ultimate) will be able to download the software, which includes a copy of Windows XP SP3 and a license to run it virtually. Integration with the host operating system should be present, and users can expect to be able to launch virtualized applications directly from the host interface (similar to what one could do with VMware Fusion's Unity mode on a Mac).

As pointed out here, XPM is fraught with security concerns. Indeed, it appears that the XPM VM needs to be managed as a separate node on the network, and will require its own anti-virus, patch management and management software. But that's just the tip of the iceberg.
