The latest data from the exo.repository shows Windows 7 driving a measurable surge in average RAM configurations across the nearly 24,000 registered xpnet.com contributors. According to repository snapshots taken in the weeks following the Windows 7 launch, the average RAM configuration for PCs running Microsoft’s newest OS has increased from 3.15GB on November 30th, 2009, to 3.76GB on February 25th, 2010 – a surge of nearly 17%.

By contrast, average RAM sizes for PCs running Microsoft’s Windows Vista and XP have remained flat at 2.7GB and 1.7GB, respectively.

The lack of movement on these legacy OS platforms reflects the rapid influx of Windows 7 PCs into the exo.repository. An analysis of the most recent 1000 exo.performance.network network registrants shows a phenomenal uptake in Windows 7 adoption, with 62% of newly registered PCs running Microsoft’s latest version vs. 28% running Windows XP and a meager 8% still running the much-maligned Windows Vista.

Bottom Line: Windows 7’s influence is increasingly being felt across the exo.repository, with nearly 2 out of every three newly registered systems running Microsoft’s latest and greatest. And along with this uptick in Windows 7 adoption comes an increase in the average RAM configuration for PCs participating in the exo.performance.network, and by extension, a significant cross-section of the general Windows system population. This is good news for software developers who have been waiting for average RAM configurations to increase before adding new, potentially memory-intensive features and capabilities to their application designs.
