After Windows 10 Update No access to Youtube, Amazon Microsoft.com etc?

My PC did a Windows Update overnight and now I have no access to Youtube.com, Amazon.de, Microsoft.com etc. In the Edge Browser. WhatsApp's Windows app does not have Internet access. Netflix app works though.
I updated the Adobe Player, cleared cache and still nothing has changed.

Can someone help me or has the same problem?

Could be a DNS problem.

Open the CMD and lead

ipconfig / flushdns

I did, but YouTube still does not work.

Just found out that I can open the mobile site (m.amazon.de), but the smile.amazon.de not

Do you hang behind a firewall that may have the ability to restrict access?
If not, try manually setting the DNS server 8.8.8.8 for your active network adapter. Maybe then works.

That's too high for me, could you explain that to me point by point?
