我正在制作一个程序，收集有关机器的信息以进行故障排除。在以管理员身份运行程序的一些工作之后，我无法正确输出％windir％\ drivers中的所有文件。我还遇到了当前用户appdata的问题，它会抛出UnauthorizedAccessException并且不输出任何关联。我可以，我会写一个服务来解决这个问题。获得基本服务后进行测试。我还没有看到输出。以下是该服务的代码：

你会注意到我注意到一个块，以为我可能会立即访问太多信息。以下是我在安装和启动服务后得到的内容：

肯定错过了那里的一些关键驱动因素。对于我的生活，我无法弄清楚它为什么不收集信息。没有AV运行，只更新了Windows 7和VS.我检查了任何奇怪的文件过滤器管理器驱动程序，但我没有看到任何。
