My Desktop Application list

These are the applications that I need to have on my computer:

• Putty
• Cygwin
• WinSCP
• Apache Directory Studio
• Fiddler
• Burp Suite
• Eclipse
• TortoiseSVN
• Notepad++
• XMind
• Microsoft Visio
• Firefox
• Opera 
  
• Internet Explorer
  
• 7-zip
• Bullzip PDF Printer
• Paint.Net
• Windows Live
• Google Talk
• VLC Media Player

 The list have increased over the last couple of years. I would have liked to cut down, but right now I don't know where to start.
I would like comments on how I can cut down on this list.
