What are your essential programs?

What programs could you not do without? The ones that you install immediatly after formatting your computer?

For me, the only ones I can think of while I'm sitting here at work are:

Winamp - Yes, I'm one of the few people that still use winamp. Most of the people I know have switched over to WMP long ago. I'm not sure why I still use winamp - it's always served me well, and I've not seen a need for switching to WMP.

Microsoft Office - Obvous... I havn't found anything that works better (or is more universally compatable)

Norton Anti-Virus - I've always used norton, and once again, I havn't found anything that works better.

Daemon Tools - I much prefer using this over Alcohol 120% (Which I used to use). It does it's job well, and I've never had a problem making a cd or dvd copy from an image mounted by it.

Nero Burning ROM - I've tried many burning apps, searching around for a free one, but nothing works quite as well as a cracked copy of Nero

AdAware - Same situation as Nero, I've tried many others, but AdAware works best (especially the cracked SE versions, lol)

Jam it back in, in the dark.
