Thank you, first thing I found that looks like the windows that I have and I'm glad that I will not need to disassemble the frame like I thought I would!
I tried on one window. The corner of my window had a screw in it like yours, that was easy enough to remove but now it doesn’t screw in. It just drops in and there’s no resistance, like something is missing. Anyone know how to fix this? 🤷🏻♀️. My windows are old single pane in what looks like aluminum frames. My house was built in the 70’s.
Omg, solved my own dilemma! If anyone is trying this. The screw goes back in at an angle. Angle it outwards and keep trying to screw it in until it catches what I'm assuming is a channel or track inside the frame. It took a few tries but I got both corners tightened back up.
