what is runtime broker, and why does it use so much memory?

I've tried most of the options I could find on the forums. Without success.

Finally found a fix (for now anyways) using File monitor and looking for Runtime Broker, I was able to find a lot of activity on my pictures. Went to the photo app and removed the "Source" folder in the settings it had added by default.

So far, runtime broker is no using <1% CPU and <10Mb of memory...

Hi,

Things have moved on, (three years for a start), I have just installed Windows 10 and 'runtime broker' is hogging and using massive amounts of CPU and memory. I have 4ghZ of CPU and 12 GB of RAM.

I have now had to 'end process' of this twice. In each case my overtaxed system came back to life with no noticeable side effect.

in task manager there is process called Runtime Broker. and it uses over 600 MB of my ram. putting my average usage at 60% on my 4 gig laptop. not noticed any performance issues yet. just a lot memory being used. makes me think of windows vista almost bc it had same issue in past. it would use all system resources.   

Found the solution to the problem:

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.

Find the following entry:

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

Change the 3 to a 4.

[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.)

I have the same problem with Runtime Broker in ODS windows 10. I just closed it and I'm going to restart. I figure it is my security software that triggers it also as others have discovered.

The thing is that windows has its own security software. Another app like Norton or McAfee is superfluous. I got McAfee free with my ISP. I'd had issues with the Norton and didn't renew.

Even if you close it in the task manager window Runtime broker starts itself again burning more CPU than before.

I guess the only thing to do is uninstall my McAfee, or perhaps return the computer to 8.1 before the month trial is over and OS 10 becomes permanent.

Actually I just developed this problem with Runtime Broker after upgrading to Windows 10. I find window 10 ripe with problems. Despite the fixes for them that make them selves available with a search on the internet, more problems apparently keep popping up.

in my case, this solution is not helpful.

Whenever I interrupt the process "Runtime Broker", it after a few minutes back running again bringing the memory usage and CPU usage increases to maximum levels, making the system unstable and terribly slow.

Please fix! This issue is becoming very annoying ... rather I go back to the old 8.1
