Hi, I've the same problem . Did you fix it?
I tried to clear the DNS with the following prompt command : ipconfig/release , but didn't fix the problem

3 or 4 days ago all work well an I was able to change the DNS. Could be something releated the mandatory update came from windows in the last days?

Bye

I would think about running a system file scan using the sfc /scannow command typed or copied into an elevated command prompt.

It may take a few scans with reboots between each scan in order to fix any system file problems.

Something is messed up with the system files I'd say. A virus scan would also help.

Code:
sfc /scannow

Hi , yesterday I tried to start windows in "safe mode" loading the base function and the network. All ran Ok and I was able to modify the DNS.
I restarted the machine in normal mode and the problem still present.

I'll try to run the command suggested by Chev65. I'll post the result this evening italian time

bad news, I ran the sfc scannow but nothing was found and the problem still present. I tried to replace the file TCPIP.sys in the Windows\system32\drivers with another copied from one pc that is running well , but nothing is changed, the problem still present.

Any other suggestion?
