Window / Window Room:

Window or Window Room is a map callout for a position built around a window opening, usually in or overlooking an interior room. In Counter-Strike 2, the term helps teammates quickly identify the exact area for rotations, utility, and enemy positions without needing a full description.

Its meaning depends on the map, since many CS2 maps have their own Window or Window Room callout. Players use it to coordinate peeks, smoke lines, and crossfires around sightlines through the window.
