While working on one of the small freelance project there was a requirement to find whether launched application/process is minimized or Maximized (For example when I open Microsoft excel what is the state whether it is minimized or maximized). This value of window state you can easily get with UIAutomationClinet .net class object. You can more read about the object on https://docs.microsoft.com/en-us/dotnet/api/system.windows.automation.automationelement?view=netcore-3.1. Below is the screenshot, In the result it shows 3 states non, minimized or maximized.
