Footware budget

Customer: So, when I got Windows I had no clue it would require a footwear budget…
Support: A what?!
Customer: Yeah, it says so here… it needs new shoes.
Support: I am fairly certain Windows does not require shoes…
Customer: In fact, you’re right… It asks for boots.
Support: OK. Can you read the message from Windows for me?
Customer: In order to finish this installation, please reboot.
