conemu and console2 emulators not getting new path variable

When you are using alternative tab based terminals like ConEmu or Console2, you need to restart the terminal, not a single console (read tab)!

This is because child processes inherit their environment their direct parent process, not from the system!

Sometimes explorer (or whatever shell you are using to start ConEmu) needs to be restarted, as in you have to kill explorer.exe, so your start menu disappears and relaunch it from task manager. If all else fails, log off and on again.

Even if ConEmu is closed, there is a ConEmu64.exe process. Need to kill it.
