a little research seems to pinpoint the problem to a set of updates in about mid 2011, if people are curious.the way this seems to work, though, is something like this:

1) microsoft breaks something.
2) hardware companies refuse to learn how to change their drivers to fix it.
3) people get frustrated and buy new hardware that plows over what ms broke with increased speed/power.
4) profit.

the result is that increases in hardware performance are merely being used to correct windows, which gets more and more broken with each release cycle. we're constantly forced to upgrade to maintain stasis. it's like they've found a way to mimic inflationary monetary policy. let's just be happy those fucking cloud computers never caught on, or we'd be really fucked.

for now, quick fix is to put yourself behind a good router, lock your OS down the smart/hard way, don't have browsing habits that are comparable to your clueless grandmother (NO IT'S NOT A GOOD IDEA TO RUN CUTECATS.EXE), never ever launch internet explorer (i've taken the approach of actually deleting the IE dlls altogether, which is technically illegal, but whatever) and stop updating windows...

or install linux. if you don't have expensive music hardware without linux drivers.
