Many freeware applications are updated on a regular basis, sometimes monthly or even weekly. These updates may not be massively significant, but can make applications more stable. If you don't visit download or software publisher's sites, there's no way of telling if an app has been updated. A useful and convenient way of keeping software updated is to use an auto-update tool, so you don't have to check manually.

UpdateStar 5.1 is an auto-update tool that automatically finds updates for any applications installed on your PC. This latest v5 is more likely to find updates for installed applications than previous versions, but it still may not find updates for everything you may have installed.
