更新后Win10上的Anaconda Python3.5：无法加载任何dll

Question

当我更新Windows10时，Anaconda Python找不到所有的dll ......

import numpy as np

ImportError                               Traceback (most recent call last)

      4 import matplotlib.pyplot as plt
      5 from mpl_toolkits.mplot3d import Axes3D

     13         env_added.append(envkey)
---> 14 from . import multiarray
     15 for envkey in env_added:
     16     del os.environ[envkey]

ImportError: DLL load failed: The specified procedure could not be found.

所有dll都会发生这种情况，例如scipy，matplotlib等。
