I'm not sure if this was caused by a random string of keystrokes I entered or what, but my start menu and taskbar now look kind of strange:
I had pretty much the default before. As you can see, all my icons have disappeared and I now have a "back" button. Clicking the windows icon does nothing, and on top of that, I can't minimize or resize any windows I have open.
I've tried restarting my computer to no avail! So what's gone wrong?
