The biggest problem with Windows is there are all kinds of inconsistencies. For example, last night I wanted to try the shortcut for creating a new Excel Spreadsheet. When I use the File menu, it shows me the "equivalent" shortcut is control-N, and it allows me to select a template on the right-hand side of the screen. When I use control-N, however, I can't select a template!

Another issue is that I can't find control panels and wizards that I've somehow wandered into earlier. For example, how do I roll back to a restore point? I know I've done it before, but yesterday I couldn't find a way to get there! I brought up the System control panel, and it only let me configure how much disk space to use for the system restore feature, not configure which restore point to roll back to! Argh!
