You might not think it, but Microsoft's Windows Operating System has been listed as one of the most secure OSs available.

According to Symantec in its 11th Internet Security Threat Report the Windows OS had the fewest number of patches and the shortest average patch development time of the five operating systems it monitored in the last 6 months of 2006.

While Apple has always been perceived to be the more secure of the two, the report outlines that over the same timeframe Symantec found 43 vulnerabilities in Mac OS X and a 66 day turnaround on fixes compared to Microsoft's 39 vulnerabilities and average of 21 days to fix them.

Of course as with any report you can twist the figures to suit your needs and delving deeper shows that of the 39 Windows vulnerabilities 12 of which were ranked high priority or severe compared to Apple's 1 high priority offering.
