I know how to remove the sashes from an old-style counterweighted window. But some of the windows in my house appear to have spring cylinders to assist them instead, and they travel in a plastic track rather than just the frame, stops, and parting bead. If anyone's familiar with these and knows how to dismount/remount these sashes, they really could use reglazing before winter...
View at top of sash showing cylinder housing lift assist spring. Note no obvious release points. !
View with inner dash lifted, showing track acting as parting stop.
Best guess I've got is unscrew inner stops, remove screws holding track, remove screws holding springs, and take track/spring/sashes out together (at least on one side). Feels like there should be an easier answer. But I may be spoiled by modern tilt-outs
