Windows Updates settings issue?

it's my first post here, don't wanna make it long, but I got a problem with my 'Windows Update' it won't show its setting's options. It only shows these settings:
Important Updates, Recommended Updates and Who can install updates, it removed the other setting sections like 'Microsoft Updates' "Give me updates for Microsoft products and check for new optional Microsoft software when I update windows" or the last settings section 'Software notification' "Show me detailed notifications when new Microsoft software is available"

Here's a screenshot of my Windows Update:
