Freeware

Like shareware, freeware is software you can download, pass around, and distribute without any initial payment. However, the great part about freeware is that you never have to pay for it. No 30 day limit, no demo versions, no disabled features -- it's totally free. Things like program updaters (for minor updates) and small games are commonly distributed as freeware. Please note that freeware is copyrighted, however, so you can't go sell it as your own software. Not that you would even think to do that...
