Git for Windows: how to apply changes in PATH without reboot?

I'm using Git for Windows on Windows 7.

When I adjust the PATH environment variable, the changes are not applied immediately for console windows.

In order to force applying the changes for a conventional console window, it's necessary to close and reopen the console.

But this doesn't work for Git Bash console window. Changes to PATH are applied in Git Bash only after reboot.

Questions:

1. Why
2. How do I force applying the changes in PATH for Git Bash without rebooting? Is there some command that can do this?

Okay, my problem was that i was starting Git Bash from a file manager's context menu. Without being restarted, the file manager remembered the obsolete PATH and somehow transferred it to Git Bash.

Thanks to @gronostaj and @Forza for testing this issue.
