The file RuntimeBroker.exe runs only when you run a Windows Store app. If after starting your Windows 10/8 computer, you do not run any app, you may not see this file running in the Task Manager. Only when you open any Store/Modern app, will you see RuntimeBroker.exe running – this is because running any Windows 8/10 app triggers the RuntimeBroker.exe into action. But even if you close the app, RuntimeBroker.exe will continue to run the background consuming near-nil resources.

RuntimeBroker.exe taking a lot of memory

RuntimeBroker.exe normally leaves very a small footprint. In some cases, RuntimeBroker.exe may consume more resources but does not release memory after the work is done, resulting in a memory leak. If your RuntimeBroker.exe consumes high memory and display high RAM usage, you may want to investigate your installed 3rd-party apps. Specifically, look at 3rd-party apps which you may have installed after you noticed this problem – especially those which display Live Tiles. Uninstall them one after the other and restart your PC and then check the memory utilization, to try and isolate the problematic app.

You may also press Ctrl+Shift+Esc to open the Task Manager. Locate Runtime Broker under the Processes tab. If it’s using more than 15% of your memory, you probably have an issue with an app on your PC. In this case, you need to stop the Runtime Broker process. Select it, right-click on it and then click on End Task.

It should help.
