Today there are many free open source software options, and often cross-platform alternatives to costly Windows software. In this article I have summarized the most important free open source alternatives to standard commercial Windows programs.
LibreOffice replaces Microsoft Office
LibreOffice was founded by former developers of OpenOffice over concerns that Oracle would turn it into a commercial product. In April this year, however, Oracle announced that it would discontinue commercial development of OpenOffice and make it a purely community-based project [Wikipedia]. Nevertheless, LibreOffice has become an alternative for both OpenOffice and Microsoft Office.
Like its commercial counterpart, LibreOffice comes with a word processor (Writer), a spreadsheet program (Calc), a presentation tool (Impress), a databases manager (Base), and a lot more. It is fully compatible with standard Microsoft Office file formats but users must remember to save or export their files in the respective format.
LibreOffice’s number one competitor is of course OpenOffice.

GIMP replaces Adobe Photoshop
GIMP, an acronym for GNU Image Manipulation Program, is a cross platform graphics editor, which can serve as a simple paint program, but also supports advanced features, such as photo retouching, batch processing, or image format conversion.
Another option for Windows users is Paint.NET, which some say is easier to use than GIMP, especially if you are not looking for advanced features.
