Ok, So Why Would I Agree To This?

Got this install notice on my PC. It wants to install "Windows Genuine Advantage". It basically sets up a program that regularly scans your computer and tells you if your version of Windows is "genuine and properly licensed". So here are the two possibilities....

1) I know my computer is properly licensed and I don't need some program periodically spinning on the computer taking up processing time just to keep reconfirming what I already know.

2) I know my computer has a pirated copy of Windows and I don't need some program giving me periodic reminders to buy a real copy of Windows.

So, why would I agree to this?
