Secunia PSI scans your system for vulnerabilities and reports its findings. The overview provides an overall score (given as a percentage) as well as basic information about your programs, displaying the total number that are patched, insecure, and no longer supported (EOL).

Apart from providing an exhaustive listing of potential threats, Secunia does an excellent job of linking to the downloads needed to correct them. You'll have to download and install each file individually, but at least they're all accessible from a single page.

Secunia PSI is a free download for Windows only.
