The Underscore Archives

Hi,

I'm currently defining our companies basic XP Pro desktop image and am
trying to build a list of software that should merit inclusion.  So far I
have:

Adobe Reader 8 (Considering FoxIt Reader instead)
Access Runtime
Excel Viewer
PowerPoint Viewer
Word Viewer
Visio Viewer
Office 2007 File Compatibility Pack
Office 2007 PDF Save
PowerShell 1.0
PowerShell Community Extensions 1.1.1
SnagIt
Internet Explorer 7
FireFox
.Net Framework 3.5
Putty
7Zip Archiving Tool

Is there anything else anyone would consider worthy of inclusion?  Any
favorite little bit of software you consider unmissable?  Free would be
preferable but any suggestions considered.

Cheers
Richard
