Microsoft periodically releases new patches for bugs and vulnerabilities every Tuesday, however they also release something called as Service packs which offer a cumulative update for your computer.
If you are a Windows Vista user, you can download the latest service pack, Windows Vista SP2 which is now publicly available to users.
The new build is a release candidate which should make the update more stable, however you will have to have Windows Vista SP1 (Service Pack 1) installed before you can install the SP2 on your computer.
