Get list of background windows.

Question

What would be the best method to retrieve a reference of each window located in the background in reference to another window? I want to apply a blur animation to every window except one that has IsTopMost set to true. My goal is to focus attention on a tool window that displays updates on a long running process. I currently have a static class that holds a reference to each open window to prevent multiple instances from running. I could use that; however, I want to make this code reusable in other apps.

您不需要自己的列表，这里有Application.Current.Windows 。
