I am on Windows 7 and I have a D-Link Wi-Fi router. I become very helpless when my cousins come over for weekend and suck up all the Internet bandwidth by streaming Netflix and YouTube. I just to limit Wi-Fi bandwidth for the guests. Is there a way to do this?

You need to do this on the router, your version of Windows is almost irrelevant. You might want to post your router model if you are looking for serious answers rather then general background info. –  davidgo Apr 10 '14 at 6:59

Login to your router with the default IP or using the credentials

  1. user: admin
  2. password: admin

next navigate to parental control and block the websites that use your data up. http://screenshots.portforward.com/routers/Dlink/DSL-2750U/Block_Website.jpg

How to set QOS on dlink router –  Umer Farooq Apr 7 '13 at 7:40
QOS on your router won't help. By the time the packets have reached the router, the earliest that QOS on your router could do anything, it's already too late because the packets have already consumed your inbound bandwidth. –  David Schwartz Mar 11 '14 at 7:03

There should be an option to blacklist traffic by MAC Addresses. I you know their MAC address you can limit traffic to their devices.
