Window will not stay up

A home owner from East Brunswick, NJ says:
I have several of these windows throughout the house. Three of them will not stay up.
Picture shows the type of spiral devise that is suppose to keep them from dropping.
Could you help me fix this.
Thank you

It's hard to tell exactly what you have based on these pictures, but I can tell that you have tilt window spiral balances. I recommend looking at this section to determine what you have. I also recommend watching the video below.
