IT admins who find themselves in a tug-of-war with the bean counters over whether or not to deploy Windows 7 in place of XP have a bit more ammunition today to plead their case. In a new Security Incident Report released this week , Microsoft unsurprisingly lays out some compelling reasons to upgrade.
The Key Findings Summary is of particularly interest. It's here that Redmond's research team points out several benefits, including the fact that in Windows XP, Microsoft vulnerabilities accounted for 55.3 percent of all attacks in the studied same (comparing targets of browser-based exploits). In Windows Vista and Windows 7, however, the proportion of Microsoft vulnerabilities is a lot smaller and accounted for just 24.6 percent of attacks in the studied sample.
Microsoft's report also points out that the 64-bit versions of Windows 7 and Windows Vista SP2 had lower infection rates than any other OS in the second half of 2009, while the 32-bit versions both had infection rates that were less than half of Windows XP with SP3, the most up-to-date service pack currently available.
