Is any better way to terminate chrome.exe on windows

I want to programmatically exit Chrome.exe via C++ on Windows OS.

Now, I use Terminate() API, however, as Chrome.exe has many instances, when kill Chrome.exe, it will popup an UI which explains that an extension crashed. I think this is because we kill extension process.

So is there any graceful method that can make Chrome.exe exit. Thanks!

As of 2024, such terminations crash Chrome, and you will see a popup with a proposition to restore tabs from the previous session.

I'd recommend sending the message "WM_CLOSE" to the chome processes using EnumWIndowsProc, so Chrome can handle the closing by itself.

Code sample:

BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
    DWORD windowProcessId;
    GetWindowThreadProcessId(hwnd, &windowProcessId);

    DWORD targetProcessId = static_cast<DWORD>(lParam);

    if (windowProcessId == targetProcessId)
    {
        PostMessage(hwnd, WM_CLOSE, 0, 0);
    }
    return true;
}

void sendMsgToProc(DWORD pId)
{
    EnumWindows(EnumWindowsProc, static_cast<LPARAM>(processId));
}

However, there is an issue. If the user is editing text or writing an email, the browser may show a warning popup indicating that the user may lose their data, asking for consent to close Chrome.

int CTestDlg::KillChromeProcess()
{
    HANDLE hProcessHandle;  
    ULONG nProcessID;
    HWND TheWindow;

    TheWindow = ::FindWindow( _T("Chrome_WidgetWin_1"), NULL );
    ::GetWindowThreadProcessId( TheWindow, &nProcessID );
    hProcessHandle = ::OpenProcess( PROCESS_TERMINATE, FALSE, nProcessID );
    return ::TerminateProcess( hProcessHandle, 4 );
}

"Chrome_WidgetWin_1" you can use Spy++ to get.
