This weekend I finished setting up a 
fresh triple-boot install on my MSI laptop. With my operating systems 
ready to go, the time had come to start reinstalling applications. While
 it wasn't a conscious decision, I noticed that the majority of my apps 
were Open Source - so I decided to keep the ball rolling.
Even if you haven't just gone through a
 reformat, these are great applications and well worth installing. If 
you have, then hopefully this list will provide you with a solid base of
 programs to get you started with your fresh, new Windows install!
Web Browsers: Chromium, 
Firefox
 They excel at different things, so I install both browsers by default. 
Chromium is great for all-purpose surfing, while I use Firefox and my 
favorite extensions to tackle my daily web-based work.
 
Office: OpenOffice.Org, 
Sumatra, 
PDFCreator
 For lightweight PDF reading and creation from any Windows app, Sumatra 
and PDFCreator are solid options. OpenOffice.Org, well, it's the name to
 beat in open source suites.
 
    
Media: Songbird, 
VLC, 
Handbrake, 
DVD Flick
 I've been using VLC for ages, and it does everything I need as my video
 player of choice. Audio duties I leave up to Songbird, which has 
matured into a fantastic application over the past two years. 
 I use Handbrake to, uh, rip my non-encrypted, personal DVDs. DVD Flick lets me burn said rips back onto a disc.
 
File Transfer: Free Download Manager, 
Cabos, 
eMule
 FDM is a very underrated torrent app, and it has plenty of other 
download-boosting abilities as well. I chose it over Vuze because I need
 FDM's extras (partial zips, Flash downloading, Rapidshare integration) 
more than Vuze's additional media-handling chops. Cabos trims Limewire 
down to the bare minimum for the occasional one-off Gnutella download. 
 As for eMule, I use it to find things that I can't find elsewhere.
 
Imaging: ZScreen, 
Inkscape, 
Gimphoto/GimPad, 
Flickr Uploadr
 If you're comfortable with Photoshop but looking for a free 
alternative, go with Gimphoto instead of Gimp – the interface is very 
Adobe-esque. For vector image jobs, Inkscape can't be beat. ZScreen 
handles my screen captures and Flickr Uploadr, well, it does what it 
says.
 
Burning and Backup: Infrarecorder, 
WinCDEmu, 
Bonkey, and 
DirSyncPro
 These three apps make short work of mounting disc image files, burning 
just about anything, syncing folders, and keeping a current copy of your
 files in a safe location.
 
Messaging and Social Networking: Pidgin and 
Spaz
 Don't sic Mr. Stallman on me – I know Spaz is built on Adobe Air, but 
the client itself is open. As for multi-protocol messaging apps, Pidgin 
is a tough bird to beat.
 
Maintenance and Utilities: 7zip, 
Belvedere, 
Ultra Defrag, 
Disk Cleaner, 
TrueCrypt
 Lifehacker's Belvedere is a great way to organize your files and 
folders with minimal effort. Ultra Defrag and Disk Cleaner (and a 
handful of 
helpful plugins)
 keep your hard drive clutter free and performing its best. 7zip waits 
in your context menu to extract files from (or cram files into) archives
 of all kinds. For encrypting files, folders, or entire volumes, 
Truecrypt is fast and reliable.
 
Desktop Enhancements: RocketDock, 
Launchy, 
Virtual Dimension
 You don't really need both RocketDock and Launchy. If you prefer eye 
candy, go with Rocket Dock. If you're a keyboard magician, go with 
Launchy. I run Virtual Dimension because my forays into Linux have me 
hooked on the benefits
 of virtual desktops.
 
Games: AssaultCube, 
Enigma, 
FreeCiv, 
LexJongg, 
LinCity, 
Neverball, 
Nexuiz, 
PokerTH, 
TORCS, 
Tremulous, 
WinSudoku, 
Wormux, 
Zombies.
Using
 your computer shouldn't be all work, all the time. Kick back and relax 
or give you brain a casual workout with these great games. LexJongg puts
 a slightly technogeek spin on traditional mahjong. FPS fans should 
check out AssaultCube, Nexuiz, and Tremulous. FreeCiv and LinCity offer 
OSS takes on two classic PC simulations. TORCS is a solid 3d racing sim 
which will hopefully soon include online action. Wormux and Zombies are 
fun turn-based strategy games. WinSudoku and PokerTH - I'll assume you 
know what those are all about. 
 
There you go - plenty of great OSS to load on your 
own freshly reinstalled system (or a friend's)! If I missed one of your 
favorite apps or games, share it in the comments!
