See the log, the original thought is my computer can not access the Https://aka.ms/vs/15/release/installer, but the actual manual download, is able to download the normal and fast, so to eliminate the network problems, in this thank Dudu positive reply, It's not a network problem, but at least it shows concern about it.

Since it is not a network problem, it must be the computer environment is a problem, from the installation log (red marked part), should be download failed using Bits engine, and the failure may be related to some COM services, according to this idea, the following steps to successfully solve the problem.

Step One: Check if the BITS service and dependent services are turned on normally, and set to auto and enable if not turned on (I do have some services that are not turned on)

Remote Procedure Call (RPC)

COM + Event System

System Event Notification Services

Background Intelligent Transfer Service-----"This is bits.

Network Connections

The second step: if all of the above services still do not solve the problem, you need to check if there is a missing component, if any, need to fix, as follows: (my component is not missing)

windows+x, open the command prompt (administrator) and execute the following command:

Dism/online/cleanup-image/scanhealth
Dism/online/cleanup-image/restorehealth
Sfc/scannow

Step three: If there is a problem after performing the second step check and fixing the related components, you need to check the socket component and perform the following command to reset it if necessary (my need to reset)

• Type "netsh winsock reset", and then press "Enter".
• Type "netsh int ip reset", and then press "Enter".
• Type "Ipconfig/release", and then press "Enter".
• Type "Ipconfig/renew", and then press "Enter".
• Type "Ipconfig/flushdns", and then press "Enter".

After the completion of the above three steps, restart the computer, so far, my problem has been successfully solved. The way is more than the problem, we have more brains and more analysis of any problems will not be stumped.

The reason to share this resolution is because VS2017 is the first condition for everyone to learn about. NET Core, and installing VS2017 on Win 10 is also very common, and it's likely that anyone will come across a problem like me and share it.
