Open the Run dialog box by simultaneously pressing the Windows logo button + the R button. Then enter “ncpa.cpl” and click OK.
Now that the Internet Connection window is open, double-click your active network adapter.
Then click Properties and double-click Internet Protocol Version 4 (TCP/IPv4).
Search Use the following option for DNS server addresses.
Set the preferred DNS server to 8.8.8.8.8.8.8.8.8.8.8.8.
Set the alternative DNS server to 8.8.8.4.4.4.4.4.

Warning: Antivirus software can protect your computer from viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to temporarily disable it to install other software, you should reactivate it when you are finished. If you are connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
Using Regedit
It is very easy to follow this procedure:
Open the registry editor (Start menu -> Run -> Regedit).
Find the following path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Set the UseWUServer value from 1 to 0 (double-click it, change the value and click OK).
Restart the Windows Update service (Start menu -> Run -> services.msc, locate the Windows Update service and click Restart).
