block windows automatic update downloading.

[largely]

Hi, I want to block windows automatically downloading in my network. Please advice.

[imfirewall]

Windows updates can be completely blocked with these sites blacklisted with "websites black list" of WFilter:

*.windowsupdate.com
*.update.microsoft.com
*updates.microsoft.com

If that does not work in your network, please simply add "*.microsoft.com" into website black list.
