这是在Windows任务计划程序中创buildtesting任务的示例代码。 它在Windows 7 64位（pipe理员+标准帐户），也在Windows 8.1 32位（pipe理员+标准用户）上工作正常。 但是，当我在Windows 7 32位pipe理员用户上运行相同的代码时，它工作，但与非pipe理员（标准）用户帐户失败。
我search了几乎所有可能的东西，但都没有成功。
基本上，我在这里得到错误：
hr = pRootFolder->RegisterTaskDefinition( _bstr_t( wszTaskName ), pTask, TASK_CREATE_OR_UPDATE, _variant_t(), _variant_t(), TASK_LOGON_INTERACTIVE_TOKEN, _variant_t(L""), &pRegisteredTask); hr返回的值（错误代码）：80070005
这是我的代码：
