Win10 unidentified network ... no internet access, but it works

Calvin Hobbes thanks for your reply. I have read the article, but what do you suggest as a solution, should I maybe add the microsoft dns in white list or what else?

Calvin Hobbes sorry I understand that you do not use Microsoft, but if you could still help me I would be grateful because the situation has not changed. Do you think I need to take some other steps to make the changes to the nextDNS configuration effective? 

Calvin Hobbes if you mean the registry yes those entries are there. I have disabled the network card for the provider but nothing has happened yet. I just have to disable the NextDNS one, but so I have to wait some time to see if the problem is solved. So for the moment I thank you for your kindness. 

Calvin Hobbes hello, I tried to start some basic network tests and it turns out that the address "dns.msftncsi.com" is not reachable both in apparently absent network conditions and in active network conditions (NCSI active probes and the network status alert), while the "wdcp.microsoft.com" site always is. Which is rather strange when we consider the content of the article you pointed out to me. Also "dns.msftncsi.com" appears in the nextDNS log list as the other address and is not filtered by nextdns. Another strange thing that led me to add the domain "* .microsoft.com" to the white list, is that the site "web.vortex.data.microsoft.com" appeared strangely as blocked. At this point I no longer understand anything, if you can kindly help me I would be grateful. I can add that as a last thing, that the following error appears in the system event list almost at the same time as activating nextDNS "Name resolution timeout for wpad name. No configured DNS servers responded."  

Calvin Hobbes Hello, I understand very well your situation and even though the first thanks go to God for how you offered to help me, the second thanks goes to you who behaved like a good Samaritan. If God wills I will have the opportunity to solve through some other support, but to you, as mentioned above, much of my gratitude goes for how you offered yourself (if some parts are not understandable or grammatically wrong, I specifically used google for the translation , because my English is not so perfect as to allow me to forward lines of help of this type).

Terry Webbs Hello, of course I thank you for the suggestion, but it is not the case for me, in fact in the Windows settings, the option for automatic updating of Windows Update is already active. For now I have circumvented the problem through a simple script in Powershell inserted in "Planning unit" that disables / enables after having logged in, the 2 network cards: that of my provider and that of NextDNS and it seems that for now it works.
