As Austin Wilson pointed out in the second report, Windows Vista Security One Year Later",
"Also from the One Year Vulnerability Report, we see that Windows Vista in its first year had significantly fewer fixed and unfixed vulnerabilities than Windows XP in its first year: 36 fixed/30 unfixed for Windows Vista vs. 68 fixed/54 unfixed for Windows XP."Another issue pointed out by Austin is that there were 60% fewer malware infections in the first half of 2007 on Windows Vista. I look forward to the next update of the Microsoft Security Intelligence Report (SIR) to find out the impact in the second half of 2007 of increased usage of Windows Vista combined with more advanced/experienced users.
