Free Software I Couldn't Live Without

I was stumbling around the net today and I happened upon a blog entry regarding someone's list of "essential" open source software for windows. Feeling rather argumentative, I'd like to point out that this guy puts on his list several items that do the same thing. That, and some of them are just a bit crap in my opinion. So here's my top 10 pieces of free software I couldn't live without:

• Firefox
• PSPad
• The GIMP
• PuTTY
• XChat (see here for free windows builds)
  
• foobar2000
• VLC media player
• 7-Zip
• CDBurnerXP
• K! TV

Well, there's GMail too. But that's hardly actual software. And I hit my 10 anyway. So there. GET THEM ALL.
