For the last 4-5 months it was tested on Windows 10 and 7 the following method, and at least from what could be observed, everything was all right, no problems at all.
Block from Windows firewall all the inbound and outbound traffic for all the Domains.
Let go through the firewall only:
-Core-Networking DHCP-In - inbound (otherwise it seams that the internet connection doesn't work)
-Core Networking - DNS (UDP-Out) - outbound (otherwise it seams that the internet connection doesn't work)
-Browser and security software or other applications which really received updates more than one time per week - outbound (in this case, no other applications need to access the internet.
Once in a week for a few minutes let go through the firewall only the system files and services which are responsible for Windows update, or even turn off the firewall at all for a few minutes, in order to update the Windows.
If anyone please, could answer to the next two questions:
1. Do you consider that this method is a bad habit?
2. Do you consider that for a few minutes when the firewall is turned off at all, if on the system are any kind of malware which should connect to the internet, they will do it in those minutes when the system receive updates and will harm the system?
