Periodically I notice a lot of LAN traffic from my PC and looking at Task Mgr I see it is from Runtime Broker that uses 30% CPU. Ive looked at what it is for (intermediary between apps and their use of permissions) but the mystery is that it is accessing my NAS device and goes on for ages as the NAS has a lot of files on it.

What is RuntimeBroker.exe and Why is it Running?

Runtime broker is part of the security subsystem of Universal Apps (then called Metro apps). Essentially, all access to files and other resources goes through the Runtime broker.. so what this means is that its only accessing files on the behalf of another Universal app. This is probably something like the Photos app or something that searches through indexed files and catalogs them, or indexes them.

Runtime Broker kept thrashing my system, usually using 40% of my CPU although memory use wasnt much, according to the Task Manager. Im currently using Windows 10 Pro x64 version 10240.

Runtime Broker is a service called Time Broker, which can be disabled through editing the registry.

Right-click on the Start Menu Icon. Go to RUN and type regedit.exe and select OK.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker] Start=dword:00000003

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker] Start=dword:00000004

4 is Disabled, 3 is Manual and 2 is Automatic startup.

Before editing, the original value was 3. Set to 4 to disable. Just change the 3 to a 4 through the MODIFY menu selection, exit regedit and reboot your system.

After this edit, Runtime Broker no longer runs and the CPU at idle is now only 0 to 1 or 2 percent.

No adverse affects after disabling Runtime Broker on my system. (ADDITIONAL NOTE: Disabling Runtime Broker will prevent apps from the Microsoft Store from running.)

Runtime Broker was also causing heaps of eventid 10016 DCOM errors in my four comps. Problem was a Trusted Installer permissions one in the Registry. Got a fix for this, though, so these have disappeared.

I created this account so I can share the answer to the riddle.

Search for Check for updates in the Start menu.

Under Windows Update choose Advanced options.

Under Choose how updates are installed click Choose how updates are delivered.

Disable the toggle under Updated from more than one place.

Its been sharing updates with the world, using a lot of resources. It was using 40%+ on my brand new dell xps 13 i7.

Runtime broker no longer an issue, any ideas about getting live tiles to work? they stopped working when i upgraded and i have tried getting help from microsoft but they are useless

This worked for me too. I noticed that the process was getting a lot of activity but wasnt sure if it was the culprit. Thanks!
