The main reason is that win 10 version has not been updated, which can be solved by updating. After the update, it shows that the Internet cannot be connected. The solution is to select network settings, change adapter options, right-click Ethernet, select Properties, Configuration and Advanced, and disable the one at the beginning of ipv4. Wait a minute, and the network will be restored. The third problem is that you can't click Install, and it's not good to modify DNS and win 10 storage cache.
