+- `noRestartAutomatically.xml`: Starting in Notepad++ v8.5.8, Notepad++ is a [Restarable App](../other-resources/#restartable-app).  If you would like to _disable_ Notepad++ from being restartable, add an empty config file called `noRestartAutomatically.xml` into `%APPDATA%\Notepad++\` (for normal installations) or the Notepad++ installation directory (for other configuration settings).  If that file exists, and you'd like Notepad++ to be restartable again, just delete that file.

If you want to prohibit that logfile from being created, delete this config file; but that will mean that you will not be able to provide the useful information to the developers if a crash causes issues for you; delete at your own risk. This config file _must_ go in the Notepad++ installation folder; it will not be recognized in the `%AppData%\Notepad++` hierarchy or in the cloud settings folder. (New to v8.1.9.3.)

+## Restartable App
+
+Windows 10 and Windows 11 have a "restartable apps" feature (**Windows Start Button > Settings > Accounts > Sign In Options > Restart Apps**) which automatically saves the state of various "restartable apps" when you log out of Windows then back in.  Starting with v8.5.8, Notepad++ is now a "restartable app" -- so if you log out or reboot with Notepad++ running, and have that Windows setting active, then when you next log in, Notepad++ will reload right where you were.  If you would like to _disable_ Notepad++ from being restartable, add an empty [config file](../config-files/#other-configuration-files) called `noRestartAutomatically.xml` into `%APPDATA%\Notepad++\` (for normal installations) or the Notepad++ installation directory (for other configuration settings).
