How to lower the priority (QoS) of a heavy traffic program to not block your Internet browsing

Do you have some rogram that heavily sends traffic so that it clogs your Internet? Just lower the QoS for it. It will send at the same average speed, only that it won't impede other traffic.

Choose Start->Run, start gpedit.msc

Open User Configuration->Windows Settings for a usermode program, or Computer Configuration -> Windows Settings for a system service program. Find there Policy-based QoS and right-click on it.

Choose Create new policy...

Give the policy a descriptive name and enter 8 as the DSCP Value. 8 is the lowest priority for outgoing traffic.

Press Next.

Enter the full location of the app's executable file.

Press Next.

On the following screen leave all destination and all source addresses.

Press Next.

Choose TCP and UDP and leave everything else as is.

Press Finish.

Now you have the policy ready, restart the program so that it will run with the new policy applied.
