Top 10 Open Source Apps for Windows

Every Windows user should consider making these utilities part of their standard applications

1. FileZilla 2 of 11

FileZilla isn’t the prettiest Windows application. However, it gets the job done, providing a wealth of options to streamline and automate batch transfers.

2. VirtualBox 3 of 11

Watch out, VMware! VirtualBox 3.0 now supports up to 32 virtual CPUs per guest OS session, making it the new class leader in desktop virtualization scalability.

3. OpenOffice.org 4 of 11

OpenOffice.org is the quintessential free open source application, with numerous derivative works -- like the Novell-driven Go-OO.org variant -- providing an endless variety of custom-tailored solutions.

4. Firefox 5 of 11

Firefox is another standard bearer for the free open source movement, with features that surpass even those of commercially developed Web browsers.

5. Paint.Net 6 of 11

Though Paint.Net may not be ready to take on the best-of-breed commercial offerings, it still provides more than enough muscle to satisfy all but the most demanding artists.

6. Media Player Classic 7 of 11

Don’t let Media Player Classic’s unassuming looks fool you. This is not your father’s media player, as evidenced by the wealth of internally supported media formats.

Cross over to the dark side of digital paranoia with TrueCrypt’s hidden volume option -- 007, eat your heart out!

Forget Adobe Acrobat. With PDFCreator you can generate PDFs on the fly, with a wide range of security and digital authoring components.

9. 7-Zip 10 of 11

7-Zip’s LZMA-based algorithms deliver excellent compression ratios -- for example, deflating a megabyte of files to a package of just 64KB in size.
