One or More Network Protocols Are Missing
The error that one or more network protocols are missing from this computer is an error which is encountered when network connectivity requires Windows ¬-Sockets registry entries. When these entries get missed, this error gets triggered and is reported by Windows Network Diagnostics. This will show up when your system doesn’t connect to the internet and you try to diagnose the problem by clicking the Diagnose button. It might be possible that you are able to pink your destination address but your browser might not be able to ping the same.
The root cause of this problem, in major cases, is the inconsistency in Windows Sockets API which is also known as Winsock. It is responsible for both incoming and outgoing network requests of the programs. This problem can also emerge from your Internet Provider, but if the internet is working just fine on other devices that are connected to the same ISP the there is no issue with the ISP and you can proceed to other troubleshooting steps.
Here are some troubleshooting procedures for one or more network protocols are missing on this computer Windows 10 that you can imply.
One or More Network Protocols Are Missing on This Computer
Procedure 1: Restoring the missing Protocol Files
You can download and run Reimage Plus to scan the corrupt files that might be hampering with the network connectivity. If it finds any corrupt files then it will repair them.
Procedure 2: Disabling IPv6
IPv6 is the successor to IPv6 in network connectivity but IPv6 is supported by very few networks. The network administrators believe that it is better to keep this IPv6 disabled until it gets fully phased out. So, this might be a reason to your problem. You should try disabling this IPv6 connectivity and work with IPv4.
Procedure 3: Resetting Winsock
As mentioned above the major reason for the triggering of such errors is Winsock corruption. It is observed that the issue gets resolved as soon as we reset the Winsock. You can follow the following steps to reset the Winsock.

netsh winsock reset catalog
netsh int ipv4reset reset.log
netsh int ipv6 reset reset.log
Now right click on the file that you have created and click Run as Administrator. Now, look for access denied option. If you encounter such message then perform the steps given below otherwise press any key when it asks in the black window to reboot the system. Test once after the reboot.
