Every few months at work I check for upgrades of the software that I use. I have the normal Windows XP Pro SP2 with Office 2k3 and Acrobat Reader Installed.

The rest of my software that I use on a daily basis is open source.

• GIMP 2.2.14 - Image editing
• PuTTY 0.60 - SSH and Telnet access to Linux boxes also used by FWBuilder to deploy firewall scripts
• Firefox 2.0.0.3 - Web browsing
• Thunderbird 2.0.0.0 - Access my IMAP email account
• Scribus 1.3.3.2 => 1.3.3.9 - I use this to generate barcodes, actually it's supposed to be for desktop publishing
• Inkscape 0.44.1 => 0.45.1.1 - Very useful for designing signs and anything that involves arbitrary scaleable font sizes
• Dia 0.96.1-4 - I draw Network diagrams with this
• Cygwin 1.5.24-2 - Use the bash environment and sometimes perl and also if I want to run sshd on windows
• OpenOffice 2.2.0 - Do lot of my documentation in odt format. Nice export to PDF feature
• Notepadd++ 4.0.2 => 4.1.2 - I found notepad.exe wasn't featureful enough. This has the great ability to find and replace regex's
• QCAD 2.1.2.8 - 2D cad, easy to use at 46USD a year well worth it.
• FWBuilder 2.1.11 - Graphical firewall rule generator becoming very good tool to manage multiple firewall rulesets and keep them versioned.
• TortoiseSVN 1.4.3 - Subversion client for windows

A lot of these products now have a Help => Check for updates... link so it's easy to keep them current
