Hmmm.
1. Technically a no-brainer, as this should be pretty standard on any PC (Windows or non). However, viewing this as a list meant for companies where the IT shop is on the small (or possibly somewhat disorganized) side, I can see where it might bear repeating.
2. Good to remember, although the emphasis will probably be more on *reading* PDFs than creating them, so the focus will probably be more on Adobe Reader.
3. Unless the IT shop guys really have an anti-IE bias, most IT shops will stick with the default IE...although they'll most likely lock it down somehow (i.e. Content Advisor, limiting the tabs that show up under Internet Options, etc.).
4. Most places won't need a media player. For those that do, the majority of audiovisual files they run into will run on WMP. For those that don't, they can always download a free codec (i.e. K-Lite) to handle it.
5. Kind of a generic catchall category, so not much to really comment on.
