Office Assistant & Unzipping Files in Windows XP

Office Assistant Error
I have a user who is getting this error:

There is no office assistant character files present on the system.
Please run setup in maintenance mode and install at least one character.

After a quick search, it seems this is because we often update Office 2000 around here by adding Outlook 2003. When this is done, a second Office Assistant is installed and the two then fight over control.

The instructions on this site suggest an uninstall/reinstall should fix my issue. I have plans to do so tomorrow.

Unzipping Files in Windows XP
I often have new users of Windows XP asking me to install WinZip for them, and while this is a fine product, it is no longer needed.

I found a nice site with pictures that I like to send to users so they can do this on their own, and wanted to document it here. There is no need to reinvent the wheel on this one.
