Answer by user1439716 for Unable to Edit Sublime Text's Default Settings

I use Sublime Text3 recently in Windows 10. I'm trying to change the file: Packages/User/Preferences.sublime-settings. And met your problem "Enable to sa ve Preferences.sublime-settings".I solve this by changing file Preferences.sublime-settings's property, in Security, edit "user"'s permissions. Allowed to modify.And then I can edit and save Preferences.sublime-settings
