Hi,
Most softwares (if not all) that were listed here are free.
I'd like to add a couple that are downloadble, but not all of them are free - just can't live without this stuff.

Mozilla Thunderbird http://www.mozilla.com/thunderbird/ - an exelent, easy to use, problem free email client that i've been using for a long time now.

Winamp http://www.winamp.com/player/free.php - a time proven media player that i just love!

Acronis True Image http://www.acronis.com/homecomputing...cts/trueimage/ - a backup utility that i use since v7, restored my data perfectly after several crashes - never thought of changing to something else - my all time favourite!
