SetForegroundWindow Win32-API not always works on Windows-7

The SetForegroundWindow Win32-API function is used to bring a window to the foreground and give it focus. However, it may not always work on Windows 7 due to certain security enhancements introduced in the operating system.

One possible reason why SetForegroundWindow may fail on Windows 7 is because of the User Interface Privilege Isolation (UIPI) feature. UIPI restricts applications from sending messages to higher integrity level processes, which can prevent a lower integrity level process from bringing a higher integrity level window to the foreground.

Another reason could be related to the focus-stealing prevention feature in Windows 7. This feature prevents applications from stealing focus from the user, which can be particularly useful in preventing malware from taking control of a user's system.

To ensure that SetForegroundWindow works correctly on Windows 7, you can try the following:

1. Ensure that the window you are trying to bring to the foreground is not running with higher privileges than your application.

2. Use the AttachThreadInput API to attach the input queues of your application and the target window's thread before calling SetForegroundWindow.

3. Use the AllowSetForegroundWindow API to grant your application permission to bring the target window to the foreground.

4. Consider using the SetWindowPos API instead of SetForegroundWindow to adjust the position of the target window.

If you continue to experience issues with SetForegroundWindow on Windows 7, you may need to consider alternative methods for achieving the same functionality.
