如何使用.NET应用Windows组策略？

Question

是否可以使用.NET应用（和删除）Windows组策略设置？

我正在开发一个应用程序，需要暂时将机器置于受限制的，类似于kiosk的状态。 我需要控制的一件事是访问USB驱动器，我相信我可以通过组策略来实现。 我希望我的应用程序在启动时设置策略并在退出时还原更改...这是我可以通过.NET框架调用做的事情吗？

这些是我的主要要求：

• 启动控制台应用程序时应用组策略设置。
• 确定策略拒绝用户操作的时间并记录它。
  • 登录系统安全日志是可以接受的。
• 当我的应用停止时，还原我的政策更改。

尝试使用IGroupPolicyObject

bool SetGroupPolicy(HKEY hKey, LPCTSTR subKey, LPCTSTR valueName, DWORD dwType, const BYTE* szkeyValue, DWORD dwkeyValue)
{
    CoInitialize(NULL);
    HKEY ghKey, ghSubKey, hSubKey;
    LPDWORD flag = NULL;
    IGroupPolicyObject *pGPO = NULL;
    HRESULT hr = CoCreateInstance(CLSID_GroupPolicyObject, NULL, CLSCTX_ALL, IID_IGroupPolicyObject, (LPVOID*)&pGPO);

    if(!SUCCEEDED(hr))
    {
        MessageBox(NULL, L"Failed to initialize GPO", L"", S_OK);
    }

    if (RegCreateKeyEx(hKey, subKey, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &hSubKey, flag) != ERROR_SUCCESS)
    {
        return false;
        CoUninitialize();
    }

    if(dwType == REG_SZ)
    {
        if(RegSetValueEx(hSubKey, valueName, 0, dwType, szkeyValue, strlen((char*)szkeyValue) + 1) != ERROR_SUCCESS)
        {
            RegCloseKey(hSubKey);
            CoUninitialize();
            return false;
        }
    }

    else if(dwType == REG_DWORD)
    {
        if(RegSetValueEx(hSubKey, valueName, 0, dwType, (BYTE*)&dwkeyValue, sizeof(dwkeyValue)) != ERROR_SUCCESS)
        {
            RegCloseKey(hSubKey);
            CoUninitialize();
            return false;
        }
    }

    if(!SUCCEEDED(hr))
    {
        MessageBox(NULL, L"Failed to initialize GPO", L"", S_OK);
        CoUninitialize();
        return false;
    }

    if(pGPO->OpenLocalMachineGPO(GPO_OPEN_LOAD_REGISTRY) != S_OK)
    {
        MessageBox(NULL, L"Failed to get the GPO mapping", L"", S_OK);
        CoUninitialize();
        return false;
    }

    if(pGPO->GetRegistryKey(GPO_SECTION_USER,&ghKey) != S_OK)
    {
        MessageBox(NULL, L"Failed to get the root key", L"", S_OK);
        CoUninitialize();
        return false;
    }

    if(RegCreateKeyEx(ghKey, subKey, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_WRITE, NULL, &ghSubKey, flag) != ERROR_SUCCESS)
    {
        RegCloseKey(ghKey);
        MessageBox(NULL, L"Cannot create key", L"", S_OK);
        CoUninitialize();
        return false;
    }

    if(dwType == REG_SZ)
    {
        if(RegSetValueEx(ghSubKey, valueName, 0, dwType, szkeyValue, strlen((char*)szkeyValue) + 1) != ERROR_SUCCESS)
        {
            RegCloseKey(ghKey);
            RegCloseKey(ghSubKey);
            MessageBox(NULL, L"Cannot create sub key", L"", S_OK);
            CoUninitialize();
            return false;
        }
    }

    else if(dwType == REG_DWORD)
    {
        if(RegSetValueEx(ghSubKey, valueName, 0, dwType, (BYTE*)&dwkeyValue, sizeof(dwkeyValue)) != ERROR_SUCCESS)
        {
            RegCloseKey(ghKey);
            RegCloseKey(ghSubKey);
            MessageBox(NULL, L"Cannot set value", L"", S_OK);
            CoUninitialize();
            return false;
        }
    }

    if(pGPO->Save(false, true, const_cast<GUID*>(&EXTENSION_GUID), const_cast<GUID*>(&CLSID_GPESnapIn)) != S_OK)
    {
        RegCloseKey(ghKey);
        RegCloseKey(ghSubKey);
        MessageBox(NULL, L"Save failed", L"", S_OK);
        CoUninitialize();
        return false;
    }

    pGPO->Release();
    RegCloseKey(ghKey);
    RegCloseKey(ghSubKey);
    CoUninitialize();
    return true;
}

你可以像这样调用这个函数..

// Remove the Log Off in start menu
SetGroupPolicy(HKEY_CURRENT_USER,
    L"Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer",
    L"StartMenuLogOff", REG_DWORD, NULL, 1);

注意：我使用两个GroupPolicy程序集引用：C：\\ Windows \\ assembly \\ GAC_MSIL \\ Microsoft.GroupPolicy.Management \\ 2.0.0.0__31bf3856ad364e35 \\ Microsoft.GroupPolicy.Management.dll和C：\\ Windows \\ assembly \\ GAC_32 \\ Microsoft.GroupPolicy。 Management.Interop \\ 2.0.0.0__31bf3856ad364e35 \\ Microsoft.GroupPolicy.Management.Interop.dll这个框架2.0，所以有混合代码，你必须使用app.config： http ： //msmvps.com/blogs/rfennell/archive/ 2010/3月27日/混合模式具组件的内置，对版本，使用网-4-发展v2-0-50727 -错误-网络server.aspx

我就这样做了。

查看www.sdmsoftware.com/group_policy_scripting。 它不是免费的，但会完全按照你的要求行事。

我自己没有玩过它，但System.Security.Policy看起来可能是一个有趣的起点。
