The first reviews are starting to come in about Windows 7, and email admins may be wondering, "Is my email going to be more secure?" The answer is, as always, "it depends". For the most part, secure email comes in the form of good policy, and good third-party technology that works with the operating system, not specifically the operating system itself. Nonetheless, the OS can make a big difference.
Vista, despite the many complaints that have constantly been made against it, is more secure than XP.
