There are many freely available pieces of software to do a multitude of things so I thought it might be good for people to list ones that they have installed and use, you never know you might find something useful .
The only stipulation is that it must be freeware or open source unless the free version of a paid application does everything it's designed to do apart from a few extra features.

Here is what I can think of:
  • CCleaner.
  • VLC Media Player.
  • Steam.
  • IMGburn.
  • Auslogic's Disk Defrag.
  • Firefox + extensions.
  • Thunderbird.
  • MozBackup.
  • Google Chrome (would rather use this than IE9).
  • Virtual Clone Drive (virtual drive software like Daemon Tools but made by Slysoft).
  • Calibre.
  • File & Image Uploader.
  • MalwareBytes Anti-malware.
  • Spybot - Search & Destroy.
  • SpaywareBlaster.
  • Skype.
  • Windows Live Messenger + APatch (removes adverts and various things).
  • WinSCP.
  • LibreOffice (new version of OpenOffice).
  • TeamViewer.
  • Notepad++.
  • NFOpad.
  • Irfanview.
  • CDisplay.
  • Foxit Reader.
  • Terracopy.
  • Prime95 (used for stress testing over clocks).
  • WinRAR (technically not free but can be used as a free version).
  • 7-Zip (I prefer this to WinRAR most of the time).
  • Rainmeter.
  • Mediatab.
  • MSI Afterburner.
  • Filehippo Udate Checker.
