【问题描述】：

我正在使用没有扩展的 Visual Studio 2010 SP1Rel，并且 devenv.exe 进程持续使用整个内核，这使得使用 IDE 非常困难，如果不是不可能的话。 我注意到svchost.exe -k netsvcs 也在使用整个内核。 我已经运行 Process Explorer 来尝试确定发生了什么，我注意到这两个进程都有一个线程占用所有 CPU 并且两个线程都在同一个函数中 ntoskrnl.exe!KeSetEvent+0x6ca svchost.exe 的堆栈跟踪是

有人见过这个吗？我希望有人能指出我正确的方向，因为我不知道如何进行。我已经多次重启了visual studio并多次重启但无济于事。启动 VS 几分钟后，devenv.exe 的问题再次出现，并且 svchost.exe -k netsvcs 问题来来去去。 任何帮助，将不胜感激。谢谢

【参考方案1】：

我不知道为什么，但关闭我在 Visual Studio 中打开的大部分文件似乎可以解决问题

【讨论】：

哇，我多年来一直在寻找解决方案！发生这种情况时，我的电脑会变得非常嘈杂。
