Steps to reproduce

Hi All,

We are using “EnumChildWindows” API with main window class name- “ApplicationFrameWindow or Windows.UI.Core.CoreWindow” and child window class name- “TabWindowClass” to capture the URLs from Microsoft Edge browser (Accessibility tree enumeration). And this method is working fine until the below Windows 10 version:

OS:- Windows 10, version 1607 (OS Build 14393.1066)
Microsoft Edge version:- 38.14393.0.0

But with latest Windows 10 updates, the “EnumChildWindows” API fails, below are the Windows 10 version details:

OS:- Windows 10, Version - 1703 (OS Build 15063.138)
Microsoft Edge version:- 40.15063.0.0

Child window class name- “Internet Explorer_Server” is also failed; facing the same issue on both 32 bit and 64 bit Windows 10. So anyone kindly help me to solve this issue.

Kindly see the attached images for the analysis with Spy++ and AccExplorer tools for Edge version 40 and 38.
