Description

I have encountered some issues following the sample snippets to set/unset the environment variables in Windows 7 & 10.
After some research, this is what I found:

# Page 50
# Windows 7 & 10 do not have this setx command.
# change setx to set seems to be working though.
setx SOME_SECRET_KEY 1c3-cr3am-15-yummy

# Page 51
# Windows 7 & 10 do not have this unset command.
# Set a variable to empty would take it out of the environment variable list.
# set "SOME_SECRET_KEY=" would unset the environment variable.
unset SOME_SECRET_KEY
