Description

Environment data

  • VS Code version: 1.21.1 x64
  • Extension version (available under the Extensions sidebar): 2018.3.1
  • OS and version: Win10
  • Python version (& distribution if applicable, e.g. Anaconda): 2.7.13
  • Type of virtual environment used (N/A | venv | virtualenv | conda | ...): NA

Actual behavior

When open to a python file, code with the Python extension enabled is continually launching
wmic processes. This in turn backs the wmiprvse.exe service up, to the point where very
quickly it's consuming 100% of the CPU (on one core).

Expected behavior

VSCode shouldnt' cause my CPU to be fully loaded when nothing's actually happening

Steps to reproduce:

Install VSCode
Install the python extension
Open a python file.
Watch in taskmgr/process explorer as wmic processes are created repeatedly.

Disable python extension
Watch as no further wmic processes are created, and processor returns to idle.
