Title: Shutdown PC with all Windows versions
Question: How can I shutdown PC even if Windows doesn't wants to exit or NT says that you don't have privileges to shutdown?
Answer:
Simply use this code:
function GetWinVersion: String;
var
VersionInfo : TOSVersionInfo;
OSName : String;
begin
// set the size of the record
VersionInfo.dwOSVersionInfoSize := SizeOf( TOSVersionInfo );
if Windows.GetVersionEx( VersionInfo ) then
begin
with VersionInfo do
begin
case dwPlatformId of
VER_PLATFORM_WIN32s : OSName := 'Win32s';
VER_PLATFORM_WIN32_WINDOWS : OSName := 'Windows 95';
VER_PLATFORM_WIN32_NT : OSName := 'Windows NT';
end; // case dwPlatformId
Result := OSName + ' Version ' + IntToStr( dwMajorVersion ) + '.' + IntToStr( dwMinorVersion ) +
#13#10' (Build ' + IntToStr( dwBuildNumber ) + ': ' + szCSDVersion + ')';
end; // with VersionInfo
end // if GetVersionEx
else
Result := '';
end;
procedure ShutDown;
const
SE_SHUTDOWN_NAME = 'SeShutdownPrivilege'; // Borland forgot this declaration
var
hToken : THandle;
tkp : TTokenPrivileges;
tkpo : TTokenPrivileges;
zero : DWORD;
begin
if Pos( 'Windows NT', GetWinVersion) = 1 then // we've got to do a whole buch of things
begin
zero := 0;
if not OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken) then
begin
MessageBox( 0, 'Exit Error', 'OpenProcessToken() Failed', MB_OK );
Exit;
end; // if not OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken)
if not OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken) then
begin
MessageBox( 0, 'Exit Error', 'OpenProcessToken() Failed', MB_OK );
Exit;
end; // if not OpenProcessToken( GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES or TOKEN_QUERY, hToken)
// SE_SHUTDOWN_NAME
if not LookupPrivilegeValue( nil, 'SeShutdownPrivilege' , tkp.Privileges[ 0 ].Luid ) then
begin
MessageBox( 0, 'Exit Error', 'LookupPrivilegeValue() Failed', MB_OK );
Exit;
end; // if not LookupPrivilegeValue( nil, 'SeShutdownPrivilege' , tkp.Privileges[0].Luid )
tkp.PrivilegeCount := 1;
tkp.Privileges[ 0 ].Attributes := SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges( hToken, False, tkp, SizeOf( TTokenPrivileges ), tkpo, zero );
if Boolean( GetLastError() ) then
begin
MessageBox( 0, 'Exit Error', 'AdjustTokenPrivileges() Failed', MB_OK );
Exit;
end // if Boolean( GetLastError() )
else
ExitWindowsEx( EWX_FORCE or EWX_SHUTDOWN, 0 );
end // if OSVersion = 'Windows NT'
else
begin // just shut the machine down
ExitWindowsEx( EWX_FORCE or EWX_SHUTDOWN, 0 );
end; // else
end;
