21 months later, Vista is still more secure than XP

July 31, 2008 (Thursday) | Windows Vista

Last October, roughly one year after the release to manufacturing of Windows Vista, I did a comparison of how well Windows Vista was living up to its promise of being more secure than its predecessor, Windows XP. My data source was the Microsoft Security Bulletin Search page, where I tallied up security bulletins rated Critical or Important for the two Windows versions. The result? Vista had an overwhelming edge over XP. So, has Vista maintained its security edge in the succeeding nine months? I did the same comparison for that period. Go see the numbers for yourself.
