How to Fix Runtime Broker High Memory Usage on Windows

What Causes This?

Runtime Broker is a built-in Windows process that manages permissions and background activity for Microsoft Store apps. It usually uses very little memory, but it can spike when a Store app is misbehaving, too many background apps are running, or Windows notifications and tips are constantly triggering it. Corrupted temporary files, outdated apps, and a cluttered system can also make the problem worse.

Common Symptoms

• Task Manager shows Runtime Broker using unusually high memory
• Windows feels slow when opening apps or switching between windows
• Fans spin up more than usual while the PC is idle
• Memory usage stays high even after closing visible apps
• You notice lag, stuttering, or delayed response in the Start menu or Settings

How to Fix It Manually

1. Check Runtime Broker in Task Manager

   • Press Ctrl + Shift + Esc to open Task Manager.
   • Click More details if Task Manager opens in compact view.
   • Under the Processes tab, find Runtime Broker and check how much Memory it is using.
   • If there are multiple Runtime Broker entries, note whether memory drops after closing certain apps.

2. Restart the Runtime Broker process

   • In Task Manager, right-click Runtime Broker.
   • Click End task.
   • This will not damage Windows. The process usually restarts automatically if needed.
   • Watch memory usage for a minute to see if it returns to normal.

3. Turn off Windows tips and suggestions

   • Open Settings with Windows + I.
   • Go to System > Notifications.
   • Scroll down and turn off options like:
     • Get tips and suggestions when using Windows
     • Suggest ways to get the most out of Windows
   • These prompts can repeatedly wake Runtime Broker and increase background activity.

4. Disable unnecessary background apps

   • In Settings, go to Apps > Installed apps.
   • Click the three dots next to apps you do not need running in the background, then open Advanced options if available.
   • Under Background apps permissions, choose Never.
   • Focus especially on Microsoft Store apps you rarely use.

5. Update or remove problematic Store apps

   • Open the Microsoft Store.
   • Click your profile icon or Library, then install available app updates.
   • If the issue started after installing a specific app, uninstall it from Settings > Apps > Installed apps.
   • Restart your PC and check whether Runtime Broker memory usage improves.

6. Clear temporary files

   • Open Settings > System > Storage.
   • Click Temporary files.
   • Select items you want to remove, such as temporary files and cache, then click Remove files.
   • Extra clutter can keep apps and Windows services working harder than necessary.

7. Run a system file check

   • Click Start, type cmd, then right-click Command Prompt and choose Run as administrator.
   • Enter:

     sfc /scannow

   • Let the scan finish, then restart your PC.
   • If Windows system files are damaged, this can help restore normal behavior.
