Windows 8:
"Stephen Chapman, a tech enthusiast who runs the UX Evangelist site, has been beating the bushes for a few months now for Windows 8 information. He recently unearthed a number of job profiles of folks who have worked on and are working on various elements which may or may not make it into the final Windows 8 release.

"He also found a reference to more tweaks that Microsoft is making around kernel patch protection, via PatchGuard. Chapman blogged that, based on what he unearthed, “PatchGuard is apparently going to make life even a little more difficult for hackers (and anti-virus companies as well, perhaps).”
