Windows 7 Genuine Message Removal?

The direction to go to remove the genuine message in windows SEVEN upon startup

I realize the some other answer, you should buy a real copy of Windows.When you finally do, activate that online and you will never need to see that message for a second time.

Sorry David,

But you don’t have way on this planet to remove it.I recommend buying an actual version of windows.

for what exactly reason on earth do you need or need to remove it.
