Microsoft Windows XP

Installation music:
-------------------
Go to the "c:\windows\system32\oobe\images\" foler and open either
the "title.wma" or "windows welcome music.wma" files.


Minesweeper: Reveal mines:
--------------------------
Start the game then type xyzzy. Hold [Shift] for one second. Now when
you hover over the mine areas, a little black pixel will appear in the
top left hand side of the screen. It is almost invisible, and disappears
when you hover over something that is not a mine.
