//但是对于服务程序,它会提示\"拒绝访问\".其实只要程序拥有Debug权限即可:
function EnableDebugPrivilege: Boolean;
function EnablePrivilege(hToken: Cardinal; PrivName: string; bEnable: Boolean): Boolean;
var
TP: TOKEN_PRIVILEGES;
Dummy: Cardinal;
begin
TP.PrivilegeCount := 1;
LookupPrivilegeValue(nil, pchar(PrivName), TP.Privileges[0].Luid);
if bEnable then
TP.Privileges[0].Attributes := SE_PRIVILEGE_ENABLED
else TP.Privileges[0].Attributes := 0;
AdjustTokenPrivileges(hToken, False, TP, SizeOf(TP), nil, Dummy);
Result := GetLastError = ERROR_SUCCESS;
end;
var
hToken: Cardinal;
begin
OpenProcessToken(GetCurrentProcess, TOKEN_ADJUST_PRIVILEGES, hToken);
result:=EnablePrivilege(hToken, \'SeDebugPrivilege\', True);
CloseHandle(hToken);
end;
end.
使用的时候先EnableDebugPrivilege提升权限，然后KillTask(ExeFileName: string)
