A window of opportunity is the period of time for a specific action to be completed. It is usually a small amount of time and very crucial to a given situation.

In your example, window probably means "a period of time when an opportunity was available." But because it's written in past tense, "you HAD a window," it means that the opportunity has passed. For example, if you are a man, and a woman tells you that you had a window after she broke up with her boyfriend, it means that you had a chance with her then but not anymore.

Sliding doors are taking the place of windows.
No, it is not. Window is usually a noun (wall opening, or metaphorically a limit to a view or opportunity, e.g. launch window). Rarely it is a verb and means to furnish with windows.
"Window of opportunity" is the phrase I would use.
