[issue30122] Added missing things to Windows docs.

New submission from Decorater: I realized the Windows docs lacked some information so I added it. I will try to create an cherry pick for 3.6 and 3.6 as well. Also if desired I could also see if it can be applied to the 2.7 branch as well. -- assignee: docs@python components:
