"Vista will suffer the same faith as Windows XP of which support ended 2 years ago, in April 2014. The operating system will still work and wonâ€™t be restricted after that date but it can no longer be considered secure."
LOL, pardon the hysteric laughter and my rolling on the floor.
No version of Windows can be considered secure, as evidenced by Microsoft's near daily "security" patches.
Truth is that every version of Windows from Win 286 to the present has had more bugs in it at it's inception than the Amazon and more holes
than the Titanic.
BTW, 3 machines still humming nicely on XP, new Win 10 machine had OS throughly nuked and replaced with Mint.
