Solution
When Windows 10 released in July 2015, more than 16 upgrades per second were performed worldwide. Due to this, many clients reported that their Internet bandwidth was fully utilized, thus causing Internet browsing experience to become slower than ever.
To limit bandwidth used by Windows updates, first configure a shared packet shaper with a maximum bandwidth of 2Mbps.
Apply the application control profile 'default' into the outgoing firewall policy.
However, if the updates are on-going in existing session, the changes will not be applied immediately. To clear all existing sessions, use the following command:
In previous versions, it was necessary to go to application control to apply the traffic shapers, as well as in the firewall policy.
However, in versions 6.4 and above, it is possible to directly create a traffic shaper policy in the traffic shaping section.
# diagnose sys session clear
This command will clear all existing sessions, causing slight network interruption. It should be used with caution.
