I recommend reading through the list of hotfixes.
There looks like there's some decent ones, like the max usb stick transfer size tweak/fix.
A half dozen or more faster startup patches.
And few random bsod fixes.

Also today marked the day not just for this rollup, which is like kinda like a service pack btw, I recommend it...
But also today windows 8 embedded standard, the final was released to oem's.
I'm getting a copy of it, I've already got the 1st chunk of it.

Also windows 9 was leaked I guess, not really sure though.
Just saw some news on it this morning.
Doesn't really look all that interesting though.
Heard a rumor that win9 isn't gonna have x86 code, it's all x64.
Not sure if that's true or not, but if it is, maybe that's for the best, I probably need more motivation to move to unix and that would doit.
