Can that be done?

Only if you are interested in SERVICE_CONTROL_STOP.

Nah. I usually open a dozen or so browser windows with various CP threads. By the time I get around to answering the last few, anywhere from 5-25 minutes may have passed since the OP's question, thus I'm usually repeating what has already been said.

How do you do that? Can you email the code?

AbortSystemShutdown() http://msdn2.microsoft.com/en-us/library/aa376630(VS.85).aspx[^] Sample Usage:

BOOL AbortShutdown(LPTSTR lpMachineName)
{
	HANDLE hToken;              // handle to process token 
	TOKEN_PRIVILEGES tkp;       // pointer to token structure 
	 
	BOOL fResult;               // system shutdown flag 

 // Get the current process token handle  so we can get shutdown 
    // privilege. 
	if (!OpenProcessToken(GetCurrentProcess(), 
            TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) 
    {
        TRACE("OpenProcessToken failed.\n"); 
		return false;
    }
 
    // Get the LUID for shutdown privilege. 
     LookupPrivilegeValue(lpMachineName, SE_SHUTDOWN_NAME, 
            &tkp.Privileges[0].Luid); 
 
    tkp.PrivilegeCount = 1;  // one privilege to set    
    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; 
 
    // Get shutdown privilege for this process. 
    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, 
        (PTOKEN_PRIVILEGES)NULL, 0); 
 
    // Cannot test the return value of AdjustTokenPrivileges. 
     if (GetLastError() != ERROR_SUCCESS) 
    {
        TRACE("AdjustTokenPrivileges(setting) enable failed.\n"); 
		return false;
    }
 
    // Prevent the system from shutting down. 
    fResult = AbortSystemShutdown(lpMachineName); 
 
    if (!fResult) 
    { 
        TRACE("AbortSystemShutdown failed.\n"); 
		return false;
    }
	else
		m_bIsShuttingDown = false; // Reset shut down flag
 
    // Disable shutdown privilege. 
    tkp.Privileges[0].Attributes = 0; 
    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, 
        (PTOKEN_PRIVILEGES) NULL, 0); 
 
    if (GetLastError() != ERROR_SUCCESS) 
    {
        TRACE("AdjustTokenPrivileges(re-setting) disable failed.\n"); 
		return false;
    }
	return true;
}

Nope :), it's actually a very concise description of the subject at hand - the specifics of the function which handles control messages for a service. MS surprisingly actually titled the page with meaningful text. Judy

Thanks everyone for the help. The AbortShutdown() is what I was looking for. I know about the WM_QUERYENDSESSION message and how to handle it. Originally, I was looking for a way to get around the hidden window in my service, but because I have to interact with my user, I must use it.
