This policy controls whether to close Chrome completely when the last tab would switch to another browser.
When this policy is left unset, or is set to true, Chrome will keep at least one tab open, after switching to an alternate browser.
When this policy is set to false, Chrome will close the tab after switching to an alternate browser, even if it was the last tab. This will cause Chrome to exit completely.
