Expected Behavior

App starts up on login after openAtLogin is set to true. Specifically, the registry value installed includes escaping or surrounding entire path with " so the spaces don’t break startup.

Actual Behavior

App does not start on login up after openAtLogin is set to true. The registry value installed is a raw string value of the path, and spaces in that path mess things up.

Testcase Gist URL

1. Create a windows account with a space in the username
2. Log into that account
3. Install Electron Fiddle
4. Load this gist (it will automatically set openAtLogin: true) https://gist.github.com/scottnonnenberg-signal/7b5152ecafb41222a90648d782bfd509
5. Log out
6. Log back in

Note: The app should start up when you log in, but it doesn’t. This is different from users who have no space in their name. Things work as expected for them.

Additional Information
