I don't see the lock icon you're referring to. Could you clarify which app or system you're using? That way I can help you remove it.
Navigate to C:\Users, right-click your profile, select Properties, then go to the security tab. Click Advanced, highlight the SYSTEM group, tick the option to replace all child object permissions with inheritable ones from this object, edit the settings, choose Allow as the type, apply it to this folder, its subfolders and files, ensure SYSTEM has full access, click OK and see if the lock icon disappears.
