InfoWorld's Windows 7 Compatibility Testing widget offers an early assessment and suggestions for preparing.Windows 7 is coming.
Will your PC be ready?It seems like a straightforward question. However, in the aftermath of the Vista debacle, where many systems that were certified as
"Vista Capable" proved to be anything but, the process of vetting new Windows-compatible hardware has taken on new complexity.
You simply cannot count on Microsoft to provide an honest assessment of Windows system requirements. And as the "Vista Capable" experience has shown us, Microsoft's vendor partners are no better.
Hence InfoWorld's motivation in developing the Windows 7 Compatibility Testing widget: the need for a truly independent tool that can evaluate a PC's suitability to run the next version of Windows.
By taking marketing, politics, and vendor-speak out of the equation, we're hoping to provide you with an honest assessment of your PC's runtime environment, factoring in hardware configuration, current stress levels, and workload composition.
How to Get StartedNote: As with all Windows Sentinel widgets, you'll first need to register for your free
Windows Sentinel account, which my company (Devil Mountain Software) developed based on years of experience benchmarking system performance for Microsoft and Intel.
Once you've registered, download and install the DMS Clarity Tracker Agent from InfoWorld's Windows Sentinel page and allow it to collect data for a few hours during normal usage periods. Then load the widget and find out if you pass or fail (and if the latter, why).
You can learn more about the process by visiting the
Windows Sentinel page at InfoWorld.com.
What the Widget Looks ForThe widget begins with an analysis of your system's hardware; specifically, the type and speed of your CPU and the amount of installed memory.
As a Vista-derived OS, Windows 7 will no doubt levy the same kind of performance "tax" (high overall CPU utilization spread across a massive thread pool) that hobbled its predecessor. Experience has shown that, to get acceptable performance with Vista, you need at least two CPU cores.
Windows 7 will carry forward this baseline overhead while introducing new workloads (
such as a touch interface and Web services) that Microsoft is only beginning to describe publicly.
That's why we've erred on the side of caution by labeling any system with less than two cores -- or with multiple cores running at less than 2GHz -- as incapable of supporting a post-Vista Windows platform. Likewise, given Windows Vista's penchant for consuming large quantities of RAM, we're setting 2GB as the minimum memory configuration for Windows 7.
Next up is an analysis of the current system "stress" levels. Here, the widget examines three key areas of system loading: peak CPU saturation, peak memory pressure, and peak I/O contention. By evaluating a series of weighted contributing factors -- for example, the number of ready threads waiting to execute -- it calculates a compound index for each area and then takes an average of those indices to see if the system is already heavily burdened.
An overtaxed PC, no matter how powerful, will have a difficult time supporting a similar workload on top of an even more complex OS base. In other words, if Vista makes your quad-core monster sweat up a storm today, Windows 7 will have it crying for mercy tomorrow.
Finally, the widget takes an in-depth look at the composition of your current workload. The make-up of a Windows PC's workload can vary greatly from user to user. In some cases, a limited number of tasks consume the majority of the available resources, while in others the workload is spread out across many discrete tasks, with each task spawning multiple threads.
The granularity of a workload, when factored against the aforementioned stress levels, helps further qualify a given PC's suitability for running Windows 7 by letting the widget quantify what, if any, workload headroom is available for additional OS overhead.
First Look at Win 7 CompatibilityPlease note: The Windows 7 Compatibility Testing widget is meant to be a fun, easy way to get a generalized sense of a system's suitability for running a post-Vista Windows OS. It is by no means comprehensive and should not replace the detailed software testing and evaluation processes that are part of any well-rounded enterprise desktop strategy.
After all, Windows 7 won't ship until early 2010, and we won't know until then what its final requirements are. Of course, as we learn more, we'll adjust the widget accordingly.
So remember that some systems that the widget flags as incapable of running Windows 7 might in fact be capable of supporting it in a limited context. Likewise, systems that we believe will run Windows 7 just fine may prove to be inadequate depending on how workload requirements change during the intervening months.
As with any generalized analysis tool, your mileage may vary. Still, enjoy!

I agree with this article, Windows did not wow me with their simple software capable testing method. It was more or less than a simple stress test, not really testing indefinitely deep within the system using it's hardware instead of simply stressing. The assessment software was to basic, just going by what the system recognized as a base line to see if you were capable of running Vista. With this software offering to test the system of what it is truly capable of. Although we are not sure of the specs of Windows 7 just yet, this will give us a base line. I'm going to test the software myself on my Core 2 Duo system, and see if it comes up with a capable rating. I'm glad to see that a third-party was used for this tool, as Microsoft did not impress me with their capable utility. Have any of you already tested your systems? Let us know what you think, your setup, and wither or not your looking to upgrade to Windows 7. With a shipping date sometime in 2010, were still two years out, but who knows.
