What is Runtime Broker? How Runtime Broker can help fix high RAM and CPU usage issues in Windows 10?


Runtime Broker is a background process in the Windows 10 operating system. It manages permissions for Windows Store apps. Runtime Broker acts as an intermediary between these apps and system resources to ensure proper security and resource allocation.

When you run a Windows Store app, Runtime Broker starts working in the background.

Its main role is to monitor and control the permissions that apps have over system resources, such as accessing files, cameras, microphones, or any other hardware.

It acts as a security measure to protect your privacy and prevent unauthorized access to your personal data.

Let’s explore Runtime Broker Windows 10 further…. 

What is the Role of Runtime Broker in Windows 10? 

Managing Permissions for Windows Store Apps:

Runtime Broker plays a vital role in managing the permissions granted to Windows Store apps.

When you install and run a Windows Store app, Runtime Broker acts as a gatekeeper, overseeing and controlling the app’s access to various system resources.

These resources include files, folders, cameras, microphones, sensors, and other hardware components.

Runtime Broker Enforces Sandboxing of the Apps and Allocates Resources

Sandboxing is a security mechanism that isolates apps from each other and the underlying operating system.

It creates a restricted environment where apps operate within defined boundaries, preventing them from interfering with system stability or accessing sensitive information.

Runtime Broker ensures that Windows Store apps operate within their designated sandboxes.

It monitors and enforces the limitations imposed on apps, preventing them from accessing resources outside their allowed boundaries. 

Runtime Broker also plays a vital role in resource allocation for these apps. It monitors the memory usage of each app and ensures they only consume the allocated amounts of memory.

When your computer experiences high RAM (Random Access Memory) and CPU (Central Processing Unit) usage, it can result in:

  • Sluggish performance, 
  • Slower response times, 
  • Decreased overall system efficiency.

Common symptoms of high RAM and CPU usage include:

  • System slowdown: Noticeably slower system with tasks taking longer than normal.
  • Unresponsive apps: Programs may freeze or become unresponsive due to a lack of resources.
  • More fan noise: The CPU generates more heat when it’s under heavy load, causing the cooling fans to spin faster and create more noise.
  • System crashes: (Only in extreme cases) High resource usage can lead to system crashes or the infamous “blue screen of death” (BSOD).

When system resources are excessively consumed, you can experience the following consequences: 

  • Decreased multitasking
  • Slow App responses 
  • Reduced productivity
  • Overheating and hardware strain

Why is Runtime Broker Using High RAM in Windows 10?

Runtime Broker, while doing its duty, can also contribute to high RAM usage. This can be due to factors such as: 

  • resource-intensive apps, 
  • memory leaks, 
  • the cumulative impact of multiple apps running simultaneously.

Here is a breakdown:

App Complexity & Demand for Resources:

Some Windows Store apps are resource-intensive due to their complexity. When these apps are running, Runtime Broker may allocate a large amount of memory to support their operations, causing high RAM usage.

Memory Leaks:

Some apps or even Runtime Broker itself may have memory leaks. A memory leak occurs when an application fails to release memory after it is no longer needed, resulting in a gradual accumulation of memory usage.

Multiple Apps Running in Parallel: 

When multiple apps are active at the same time, memory requirements increase, potentially causing Runtime Broker to allocate more RAM to manage and facilitate communication between these apps and system resources.

Intensive Permission Monitoring

These are permissions granted to Windows Store apps. The more apps running, the more monitoring. As Runtime Broker has to verify and manage these permissions, it puts a load on the CPU. 

Complex App Interactions:

Some apps have intricate interactions with system resources. So, Runtime Broker has to perform more extensive checks and manage resource access. 

Continuous Monitoring of Apps: 

During this process, Runtime Broker evaluates each app’s requested permissions, compares them with the granted permissions, and ensures that they fall under the defined security policies. This tedious monitoring burdens the CPU. 

Frequent Checking & Notifications:

Runtime Broker is involved in handling notifications for Windows Store apps. It facilitates the display of notifications on the desktop or in the Action Center.

To accomplish this, it frequently checks for new notifications, processes them, and coordinates their presentation to the user.

How to Fix High Memory Use by Runtime Broker? 

We’ll use Task Manager to identify the Processes consuming high RAM & CPU…

Task Manager is a built-in Windows utility that allows you to monitor and manage running processes, analyze resource usage, and identify applications consuming high RAM and CPU.

Let’s Fix High Resource Consumption Due to runtime Broker in Windows 10:

  • Press Ctrl+Shift+Esc or right-click the taskbar and select “Task Manager” to open the Task Manager window.
  • Navigate to the “Processes” or “Details” tab.
  • Click on the “Memory” or “CPU” column header to sort the processes in descending order, placing the highest resource-consuming processes at the top.
  • Look for processes that consume a high amount of memory. This information is displayed in the “Memory” or “Private Memory” column. 
  • Monitor the “CPU” or “% CPU” column to identify processes that consume excessive CPU resources. 
  • Investigate the identified processes by checking their names and associated details. 
  • Now, you can either close applications, update software, or uninstall problematic programs.

How to check if the “Runtime Broker” process is running in the background on a Windows 10 PC? 

  • Open the Task Manager (Press Ctrl+Shift+Esc to open)
  • Now, go to the “Processes” or “Details” tab.
  • Look for the process named “Runtime Broker” in the list.
  • If you find “Runtime Broker” listed, it means it is running in the background.
  • If you don’t see “Runtime Broker” in the list, it is not currently running.
