Visual studio 2012 Visual Studio因高CPU使用率而锁定

我正在努力解决Visual Studio 2012 Ultimate的一个问题。它周期性地变得不稳定，并消耗大量CPU使用

它安装了sysinternals，发现它一次又一次地访问相同的windows注册表项

这会循环数百次，甚至数千次，直到我在VisualStudio上结束任务时才会结束。知道为什么会这样吗

我的机器是一个8GB内存的核心i7。我目前没有运行许多其他应用程序。内存使用率为5.6 GB/7.9 GB。磁盘使用率低且稳定。只是CPU快发疯了

+1用于深入问题的根源！注册表使用率并不能解释高CPU使用率，它充其量只是devenv.exe内部发生的任何事情的副作用。似乎有视频，但肯定不能保证。这几乎总是由外接程序引起的问题，因此请开始逐个禁用它们。
