vscode is sharing environment variables between 2 unrelated instances

[psclkhoury]

If I launch 2 different vscode instances from two different command prompts on windows, the second instance of vscode will end up getting the environment variables of the first instance.

• VSCode Version: 1.38.1
• OS Version: Windows 10

Steps to Reproduce:

1. launch 2 different command prompts on windows
2. in the first one, type set zzz=ZZZ
3. launch code
4. from the second command prompt, launch another instance of code
5. go to the terminal of both instances and check the environment variables, both of them will have the environment variable zzz

I tried it also with Git Bash on windows and the same thing happens.

This is by design currently as the windows share the same "main process".
