iTunes won't stay closed. Every time I exit the program, it just opens up again.

When I close iTunes, it won't stay closed. It will be gone for a few seconds and then will just turn on again all by itself. Does anyone know why this is happening and how I can stop it?

It doesn't matter how I exit the program. If I select File and then Exit, iTunes will close. And then it pops right back open again. If I click on the X in the top right corner, it does the same thing.

I'm running it on a new laptop with Windows 8.1 installed. Thanks for any advice.
