Windows 10: Cannot Connect to the internet when I try to update windows or install apps via internet...

My browsers work fine but when I try to updating windows it shows error encounter Your device is missing important security and quality fixes. We couldn't connect to the update service. We'll try again later, or you can check now. If it still doesn't work, make sure you're connected to the Internet.

Firstly I watched a lot of youtube tutorials followed them correctly but still could not fix. But found out my problem is with internet connection settings. So I reset all connection settings still it stays.
I recently made various change of settings unistalled macfee antivirus and a lot that I could remember. Now I could not install any app unless it is a offline installer.

internet connection problem

do any other internet using apps work? like instant messenging of some sort? you may not be connected. And no i wouldn't think mozilla firefox would fault like that, as it recieves updates and auto installs them, unless you specify otherwise.
