I got new windows in my daughter's room, and the new window sits closer
in the window frame than the old one. I went to hang up the blinds and
because the window is closer in, when I went to drill a hole for the
bracket screw instead of sheetrock I got the metal strip that builders
put on the edges of where the top of the window frame and the wall
meet. Can I just put the screws in the metal? Do I need anchors if I
screw into the metal?

Thanks!!
