In a statistical analysis performed by iolo Labs, Windows XP held the dominant market share of Windows operating systems, with a hefty 65% of the worldwide market. Windows Vista came in at number two with 34% of the market. The remaining 1% was divided among Windows 7, Windows 2000, Windows Server 2003, and Windows NT 4.

Because Windows Vista has the capability to automatically upgrade to a new operating system, the latest version of Windows – Windows 7– is anticipated to replace the majority of Vista systems. Windows XP has no ability to automatically upgrade and will likely continue to exist as a strong player in the operating system market for some time. iolo Labs will continue to analyze the operating system market and share its results.

Since the official launch of iolo Labs, researchers have identified and published 2,135 new Tune-up Definitions, which are the weekly research updates automatically delivered to System Mechanic customers.

With Tune-up Definitions, System Mechanic adapts to the latest software releases and gets progressively more effective every week – these definitions enable System Mechanic to instantly react to how different programs, settings, and services affect memory, computer start-up time, registry processing, and other key functions that impact PC performance.

iolo Labs has released a summary of its findings for a study performed on PCs during their first 24 months of use. The goal of the examination was twofold: to quantify the cumulative effects of everyday use over time on today's typical home office PC and to quantify the differences in performance in a PC that was regularly tuned versus one that was not.

The results of the study indicated that, among other things, over a two year period an un-tuned PC took up to 38% longer to start, exhibited up to 66% more CPU idle usage, and maintained up to 38% less available memory than the same tuned PC.

iolo Labs has released its findings for a study testing whether the time it takes for a PC to start lengthens as it is subjected to typical use over time and, if so, what factors may contribute to this increase. The study quantified changes by observing home office machines starting from a brand-new system to one that was two years old.

Researchers found that the amount of available memory decreased by an average of 59%, CPU usage during an idle state increased roughly sevenfold, from 0.9% to 7.5%, and the number of registry defects significantly increased, from zero to 340.

iolo Labs has released its findings for a study testing various indicators of performance related to computer responsiveness, or how quickly programs and the operating system respond to user input. The study quantified changes over time by observing home office machines starting from a brand-new PC to one that was two years old.

As part of iolo Lab's efforts to raise users' awareness about PC tune-up issues, two white papers are now available for download. Drawing from a knowledgebase of research, the papers are drafted in layman's terms and answer common questions about two critical processes that impact PC performance: the Windows registry and Windows startup.

Registry Optimization: Beyond Registry Cleaning describes how the registry becomes corrupted and bloated over time and how users can keep this critical component operating efficiently, and Clean Up Your Startup, Speed Up Your PC helps readers better understand how Windows' startup configuration can become cluttered with unwanted programs, and how this processing can be streamlined to speed boot times.
