The step to click on "Turn Windows features on or off" was missing.
After #5532 (e745436), it was no longer possible to enable ansible colorized output. Even though `ANSIBLE_NOCOLOR` has no effect *at the moment* in vagrant+ansible integration, I agree to keep it for clarity and consistence. The new `--no-color` behaviour (bug fix #5531) is now covered by a unit test. //cc @marsam, @sethvargo
