I need to remove the vertical blinds from my bedroom windows. I don't see how the part that holds the vertical blinds is connected to the wall. There is no screw visible. Help will be appreciated.

There usually are clips screwed into the wall and then your track snaps into the clip which is painted the same color as your track. Get on a ladder and look down on the track from above so you can see better. Grab the track firmly and roll the bottom edge out toward you as if you were going to continue to roll the trach right up the wall.
