Excel 2000 Easter egg
A version of Spy Hunter is included as an Easter egg in the first release of Microsoft Excel 2000[1]. It requires DirectX to work. The procedure to run it is:

Excel 2000 Spy Hunter.Open Excel.
In a blank worksheet, select "Save as" and choose "Save as web page".
Click on Publish and Add interactivity.
Save as any name you like.
Load in the page with MS Internet Explorer, Excel will appear in the web page.
Go to row 2000, column WC.
Highlight all of row 2000 and press Tab to make column WC the active column.
Hold the keys Ctrl, Alt, Shift and click on the Office Icon (It looks like four puzzle pieces put together).
Use the arrow keys to drive your car, the "0" key to drop oil slicks, the space bar to shoot, and the "H" key for headlights.
Shortly after Excel 2000's release, Microsoft officially banned Easter eggs from its software. Some corporate customers had complained that the eggs were a waste of space, and government agencies were said to be uncomfortable with the extraneous code included with the software. Another objection customers raised was that Microsoft should patch up its buggy software before releasing a driving game in Office 2000[2].

Has anyone ever heard of these?
