A process can set the foreground window by calling **SetForegroundWindow** only if: - All of the following conditions are true: - The calling process belongs to a desktop application, not a UWP app or a Windows Store app designed for Windows 8 or 8.1. - The foreground process has not disabled calls to **SetForegroundWindow** by a previous call to the [**LockSetForegroundWindow**](nf-winuser-locksetforegroundwindow.md) function. - The foreground lock time-out has expired (see [**SPI_GETFOREGROUNDLOCKTIMEOUT** in **SystemParametersInfo**](nf-winuser-systemparametersinfoa.md#SPI_GETFOREGROUNDLOCKTIMEOUT)). - No menus are active. - Additionally, at least one of the following conditions is true: - The calling process is the foreground process. - The calling process was started by the foreground process. - There is currently no foreground window, and thus no foreground process. - The calling process received the last input event. - Either the foreground process or the calling process is being debugged. It is possible for a process to be denied the right to set the foreground window even if it meets these conditions. An application cannot force a window to the foreground while the user is working with another window. Instead, Windows flashes the taskbar button of the window to notify the user. A process that can set the foreground window can enable another process to set the foreground window by calling the [**AllowSetForegroundWindow**](nf-winuser-allowsetforegroundwindow.md) function. The process specified by the *dwProcessId* parameter to **AllowSetForegroundWindow** loses the ability to set the foreground window the next time that either the user generates input, unless the input is directed at that process, or the next time a process calls **AllowSetForegroundWindow**, unless the same process is specified as in the previous call to **AllowSetForegroundWindow**. The foreground process can disable calls to <b>SetForegroundWindow</b> by calling the [**LockSetForegroundWindow**](nf-winuser-locksetforegroundwindow.md) function.</para>

		/// <para>As part of the Vista re-architecture, all services were moved off the interactive desktop into Session 0. hwnd and window manager operations are only effective inside a session and cross-session attempts to manipulate the hwnd will fail. For more information, see <a href="https://docs.microsoft.com/previous-versions/aa480152(v=msdn.10)">The Windows Vista Developer Story: Application Compatibility Cookbook</a>. If you have changed certain window data using <a href="https://docs.microsoft.com/windows/desktop/api/winuser/nf-winuser-setwindowlonga">SetWindowLong</a>, you must call <b>SetWindowPos</b> for the changes to take effect. Use the following combination for <i>uFlags</i>: <c>SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED</c>. A window can be made a topmost window either by setting the <i>hWndInsertAfter</i> parameter to <b>HWND_TOPMOST</b> and ensuring that the <b>SWP_NOZORDER</b> flag is not set, or by setting a window's position in the Z order so that it is above any existing topmost windows. When a non-topmost window is made topmost, its owned windows are also made topmost. Its owners, however, are not changed. If neither the <b>SWP_NOACTIVATE</b> nor <b>SWP_NOZORDER</b> flag is specified (that is, when the application requests that a window be simultaneously activated and its position in the Z order changed), the value specified in <i>hWndInsertAfter</i> is used only in the following circumstances. </para>
