Free and open-source software is good for you and for the world. Here is some best Windows software that we know of.
1. Mozilla Firefox:
If you haven’t switched to Firefox for your web browsing needs, do it now. It stops annoying popups and it has tons of amazing plugins that can make surfing the web even better. I could evangelize all day about Firefox, but one thing’s for sure: the first thing I do on any new Windows machine is run Internet Explorer just long enough to download Firefox.
2. Mozilla Thunderbird:
Thunderbird is an email client that has five big things going for it: it’s free, it’s full featured, it’s lightweight and runs quick, it has an unparalleled spam filter, and it protects you from those ridiculous phishing attacks by clearly indicating which emails send you to a bogus website. If you’re not already using a web-based email solution, Thunderbird should be your client.
3. OpenOffice:
If you want to replace the rest of the Office suite, your best bet is OpenOffice. It includes very nice replacements for Excel and PowerPoint (and workable replacements for Access and other Office elements). In fact, I actually prefer their Excel and PowerPoint replacements to the real thing.
4. Pidgin:
This is a very clean instant messaging program that allows you to be on AOL Instant Messenger, Windows (MSN) Messenger, Yahoo Messenger (and others) simultaneously with one program. There are other free packages that do this, but Pidgin is stable and clean and simple.
5. Sumatra PDF Viewer:
Sumatra PDF is a slim, free, open-source PDF viewer for Windows. Portable out of the box. Sumatra has a minimalistic design. Simplicity has a higher priority than a lot of features. It’s small and starts up very fast. It’s designed for portable use: only one file so you can run it from external USB drive. Doesn’t write to registry.
6. BitTorrent:
From their website, “BitTorrent is a peer-assisted, digital content delivery platform that provides the fastest, most efficient means of distributing, discovering, and consuming large, high-quality files on the Web. Our mission is simple: to deliver the content that entertains and informs the digital world.” In other words, BitTorrent allows you to download large media files and also use your bandwidth to help others download these files. Search for media files you want and download ‘em.
7. Free Download Manager:
Free Download Manager is a powerful, easy-to-use download accelerator and manager. This download utility is surprisingly attractive and full-featured for a freeware product, and its operation couldn’t be more straightforward.
8. Filezilla:
Many people occasionally have a need to FTP files to other computers; if you ever have the need to transfer files in such a fashion, FileZilla will do the job slickly and quickly.
9. Media Player Classic:
It is compact, but powerful media player. Plays anything under the sun. No install necessary. It comes bundled with K-Lite Codec Pack.
10. VLC Media Player:
If you get tired of having tons of media players on your computer, get this package that runs pretty much every media type you’ll run across without breaking a sweat.
11. 7-Zip:
It is open source Windows utility for manipulating archives. Formats 7z, ZIP, GZIP, BZIP2 and TAR are supported fully, other formats can be unpacked.

In addition to free-form drawing, GIMP can accomplish essential image work-flow steps such as resizing, editing, and cropping photos, combining multiple images, and converting between different image formats.
13. PDF Creator:
PDFCreator creates a virtual printer on your computer that, if you print a document to it from any program, creates a PDF of that document that can be read on any computer with Acrobat Reader on it. After installing PDFCreator, all you have to do is print like normal and out comes a PDF!
