I am sure all of you are still enjoying the chocolate eastern eggs you received at home, at work, at school,…
I certainly am! As I am writing down this text, I am enjoying a small chocolate egg with marzipan filling. And it tastes great!
At work, I presented a nice basket full of chocolate eggs to wish my team members a Happy Eastern and I also treated the rest of our 1st floor. I did not want anybody to have indigestion 
But, every time when I see eastern eggs, I also think about the eastern eggs that are hidden in some software programs of Microsoft. Do you know them?
I added some of them so that you can try it out (if you have the correct version). Some are really amazing. ENJOY!

(Note: this game only works on Microsoft Word 99. If you don't have it, it is avaliable for download on the internet. Also, this may work on later versions of Word. I'm not sure.)

8. hold "shift, control, M"
9. while holding, click on the product licence key box.
A window should appear (similar to an error window) with the heading: "Word Invaders", with a note below the heading saying: "/dos:cur44="
you will notice that this is what you typed earlier.
10. the window does not have any OK button, so instead type "play" on the keyboard
