The PATCH publicized by PCAdvisor somehow led me here...and here I find nothing that refers overtly to Patch CVE-2013-3660.
What I did find on this page is mind-twisting, to say the least. Is a person who is not a TECH supposed to be able to deal with whatever is written above?

AND: What in the world is up with what I hear about there being no Windows XP support after a certain date in 2014? Meaning of all the hoohah I can find online seems to come down to "And all people who use WXP will have to (HAVE TO) use W7...or perhaps W8..."
Well plainly and simply, this is coercion. Last time I checked there were United States laws against coercion.

Some brilliant person burbled "Well just run WXP and W7 side by side," WHATEVER THAT MIGHT MEAN, "and you will be able to figure out the differences between the two."

Fine. I have NO idea whatsoever how that side-by-side running is accomplished.

It would be very nice if whoever is handling the whatever it is above here referring to:
"93539 : Microsoft Windows win32k.sys EPATHOBJ::pprFlattenRec / EPATHOBJ::bFlatten Functions Local Privilege Escalation"....could have done the kindness of explaining just what the bleep this thing is about, how one might or might not use/want/need it, and so on.
Thanks very much.
