Vista updates available for performance and compatibility

There are a couple of updates which have been released for Vista which are outside the WSUS infrastructure (or rather they don’t seem to show up as updates at the moment). KB938194 is a compatibility and reliability update and KB938979 is supposed to improve performance and reliability. Essentially the first one fixes a variety of seemingly unrelated things to do with stability and things which fail or stop completely, while the second is more about things which just take a lot longer than they should. There are 64 bit versions available as well here and here.
