OUTDATEfighter is a tool to help check your system for missing application and Windows updates.
Launch the program, click "Scan for Program Updates", and after a few seconds you'll see a list of any installed programs which have updates available.
If you'd like to upgrade every application, check the "Name" box to select them, click "Update selected software", and OUTDATEfighter will download and launch each installation program in turn. This installation won't be silent - you'll have to work through all the steps, as usual - but it's still much quicker than locating and downloading the various files yourself.
It's also possible to manually download and install packages individually, just by clicking the Download button to their right.
And the program includes one or two bonus tools. An "Update Windows" tab lists available Windows updates, for instance, while an "Uninstall" tab lists your installed applications and allows you to uninstall them.
