No need to restart the shell to update path

[jamiehankins]

Issue Type: Feature Request

When you install Visual Studio Code, in the last step, it allows you to add it to various menus, and also to add it to the system path. It says that if you add it to the system path, the shell will have to be restarted for it to take effect.

This is not the case. Instead, you only need to send a WM_SETTINGCHANGE message to all windows using HWND_BROADCAST. When the shell receives that message, it reloads the environment.

Here's my StackOverflow entry for that:

Given that we don't force the restart and this is just a label, I think it's fine we leave it. I don't want to come back to this just because a restart is still necessary for Windows 8 users in certain enterprise environments, or something like that. Sorry about that and thanks for the research!
