SetForegroundWindow Win32-API not always works on Windows-7

`SetForegroundWindow` is a Win32 API that is used to bring a window to the foreground and give it focus. However, it may not always work on Windows 7 due to changes in the operating system's window management behavior.
One possible reason is that Windows 7 introduced a feature called "Aero Peek" that allows users to preview the contents of a window by hovering over its taskbar icon. This can interfere with `SetForegroundWindow`, as the user may unintentionally activate Aero Peek instead of focusing on the desired window.
Another reason is that applications running with elevated privileges (i.e. as administrator) cannot bring windows of non-elevated applications to the foreground. This is a security feature to prevent malicious applications from stealing focus and potentially executing unwanted actions on behalf of the user.
To work around these issues, you can try using the `BringWindowToTop` function instead of `SetForegroundWindow`. This function brings a window to the top of the Z-order, but does not give it focus. You can then use `SetFocus` to give the window focus manually.
Alternatively, you can try using the `AllowSetForegroundWindow` function to grant your application permission to bring other windows to the foreground. This is useful if your application needs to bring windows of other applications to the foreground. However, this function requires a special privilege and should be used with caution.
