如何使用.NET应用Windows组策略?

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\u 32\Microsoft.GroupPolicy.Management.Interop\2.0.0.0\u 31bf3856ad364e35\Microsoft.GroupPolicy.Management.Interop.dll 这是framework 2.0,所以有混合代码,您必须使用app.config: http://msmvps.com/blogs/rfennell/archive/2010/03/27/mixed-mode-assembly-is-built-against-version-v2-0-50727-error-using-net-4-development-web-server.aspx
