Following their public availability on Microsoft's Download Center, two hotfix packs for Windows Vista that improve performance and reliability are now available as optional downloads via Windows Update. They will not, however, be delivered automatically to Vista users.

Some of the changes offered by the updates include better file copy performance, faster boot times, improved compatibility with newer graphics cards, and better performance in games with advanced visuals. Those who do not want to install the fix packs manually can wait for Vista SP1, which is slated for public release early next year.
