How do I turn off the upgrade notification?

The orange box that notifies me when a new upgrade is available. I want to turn it off. I’m sure it’s simple to do this but I don’t know how. Can anyone help me?

And, btw, yes I’m sure I want to turn it off. :slight_smile:

Also, I want to turn it off without using it to upgrade. :slight_smile: (just anticipating any of the obvious answers people might throw out there)

take your licence number out of the upgrade centre

Thanks. I thought it would be something simple like that.
