It's called progress people, enjoy it.
I like performance improvements, you like performance improvements, everyone likes performance improvements; so the official release of the already leaked “Vista Performance and Reliability Patch” will please those of you who held off installing beta versions. Although this isn’t the service pack we’ve been waiting for, it’s a step in the right direction.
The patches themselves offer some significant improvements too, astonishingly, performance and reliability, including file transfer speed increases and driver compatibility fixes. While some sources claim not to have seen any improvement, I can personally testify that my overall Vista experience has been greatly less arduous since applying the updates, although admittedly I play a lot of games, a scenario that is specifically listed as being mended. Frankly, you’d have to be mad not to apply these updates, even if you don’t think you’ve had any problems.
