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.
Window - Good news, opportunity.

Opportunities for escape VS Barriers
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.
