Freeware: FileHippo Update Checker

The FileHippo Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases. These are then neatly displayed in your browser for you to download.

There are a small number of settings to better customize the update results. 

Choosing the default browser, displaying beta versions, adding program directories for scans, proxy connections, and a couple advanced options.
