As if we didn't already know it, WINDOWS is a 100% porous O.S, surrounded by a vast network of patches.
I have used it since the days of DOS,how it ever stood the test of time is beyond me,because MIcrosoft are like game makers, rather than 'fix' the problems, they opt for the cop-out, by releasing another version.
It's pretty much a fact,that Microsoft created the malware & virus industry single-handedly.
When WINDOWS disappears, our PC's will be re-born as secure devices as they were meant to be.
Up to XP, it was easy to by pass the Windows login to gain access.
