Shaping a shared connection in Windows

[mooojojojo]

I have cable internet setup on my computer, and I share it with a couple of neighbors.
The thing is that when they are downloading something, Windows gives them 50% or more of the bandwidth. Is there any way share the connection but with restricted speed for them?
