Security Improvements in Windows 7

Vista is inherently more secure than Windows XP, but it got that way because Microsoft made significant changes to the platform: changes that affected user habits and also required some fancy rewriting of drivers and such. Security improvements from Vista to Windows 7 aren't nearly as jarring. In security as in other areas, Windows 7 is "Vista, but better."
