There are indeed free softwares but most of them are simple and small kinds of programs where the features are fairly limited. Most of them would entail you to buy the license for the software if you want to gain access to all its features.
Check out some of these hardcore free software from SE-SOFT.COM. These portable softwares include a media player for your music and video needs, a tray menu to gain quick access to most frequently used applications and system commands via a customizable popup menu, an explorer that does more than what Windows own file manager can do, more screen savers for you to choose from and some neat rss tools and clients to easily read, search and manage RSS feeds or create your own without any needed knowledge on technologies like XML.
Sounds too good to be true? Well then, go download them and find out!
