The Undo function is only activated when you used an edit function on the
current presentation that can be undone. First thing to do is to go to Tools >
Options > Edit and set the maximum number of undos to a non-zero number. Keep
the number to something practical and reasonable, since the function uses system
resources and can impact PowerPoint performance. Then experiment. Add a text
box to a slide and type a word. Then press Ctrl + Z.

In addition to what Sonia has pointed out, your undoes will be reset to none
after you save your presentation. So don't expect to save something and
*then* try to undo it <g>.
