Think, You are sitting at your desk, trying to reply to a simple email, and suddenly your laptop fans kick into overdrive. They sound like a Boeing 747 preparing for takeoff.
Your PC slows to an absolute crawl. The mouse stutters across the screen. Panicking, you hit the classic "Ctrl + Shift + Esc" to open Task Manager, fully expecting to see your web browser hogging all the memory.
Instead, you see a mysterious process sitting right at the top of the list: Runtime Broker. It is casually eating up 30% of your CPU and a massive chunk of your RAM.
Honestly, the first time this happened to me, my stomach dropped. I immediately thought I had accidentally downloaded a nasty virus. I was ready to unplug my router and throw my hard drive into the ocean.
But before you panic-format your computer, take a deep breath. Runtime Broker isn't malware. In fact, it is an essential part of your operating system that is actually trying to keep you safe. It just has a terrible habit of occasionally losing its mind.
Let's dive in. We are going to break down exactly what this cryptic Windows process actually does, why it is suddenly draining your system resources, and how to fix it without breaking your computer.
What Is Runtime Broker (RuntimeBroker.exe) in Windows?
To understand what Runtime Broker actually does, we need to take a quick trip back to the release of Windows 8. When Microsoft introduced the Windows Store (now the Microsoft Store), they changed how applications worked on your PC.
These new apps—called Universal Windows Platform (UWP) apps—operate differently than traditional software. Unlike old-school programs that you download from random websites, UWP apps are heavily sandboxed. They are restricted, tightly controlled, and not allowed to just freely roam around your hard drive.
Enter the Runtime Broker.
Think of Runtime Broker as the massive, intimidating bouncer standing outside the VIP section of a nightclub. The VIP section is your computer’s sensitive hardware: your microphone, your webcam, your location data, and your private files.
Whenever a Universal Windows app (like the Calculator, the Photos app, or Spotify from the Microsoft Store) wants to access your webcam or read your files, it cannot just do it directly. It has to ask the bouncer first.
Runtime Broker checks the app's permissions. It looks at the list, verifies that you actually clicked "Allow" when the app asked to use your microphone, and then grants access. If the app isn't on the list, the bouncer denies entry.
By the way, this is a brilliant security feature. It ensures that a random game you downloaded from the Microsoft Store cannot silently turn on your webcam in the background. Runtime Broker is the digital security guard keeping your privacy intact.
Why is Runtime Broker Causing High CPU or Memory Usage?
Under normal circumstances, Runtime Broker is incredibly lightweight. If you open Task Manager on a healthy PC right now, you will likely see RuntimeBroker.exe sitting there quietly, using 0% of your CPU and maybe 5 to 10 megabytes of memory.
But sometimes, the bouncer goes completely rogue.
You might look at Task Manager and see Runtime Broker chewing through gigabytes of RAM or pinning your processor at 40% usage. This causes your entire system to lag, your fans to scream, and your laptop battery to drain in an hour.
So, what causes this digital security guard to lose its mind? It usually boils down to a few specific Windows quirks.
The "Windows Tips and Tricks" Bug
This is the most infamous culprit in Windows history. Microsoft built a feature into Windows 10 and Windows 11 that constantly monitors how you use your computer so it can offer you "helpful" tips and suggestions.
Because this feature acts like a UWP app running in the background, Runtime Broker has to constantly manage its permissions. For some reason, this specific interaction often causes a massive memory leak. The broker gets stuck in an infinite loop, analyzing the tips feature over and over again, consuming more CPU power by the second.
A Glitchy Background App
Sometimes, it isn't Microsoft's fault at all. If you downloaded a poorly coded app from the Microsoft Store, that app might be constantly pinging Runtime Broker for permissions hundreds of times a second.
If an app running in the background gets stuck trying to access your location or your files, the broker gets overwhelmed trying to answer all those security requests. The result? A massive spike in system resource usage.
How to Fix Runtime Broker High CPU Usage (Step-by-Step)
Alright, enough theory. If your fans are currently spinning out of control and Runtime Broker is sitting at the top of your Task Manager, we need to fix it right now.
Here are the exact tricks I use to tame this process whenever it acts up on my personal machines.
1. Turn Off Windows Tips and Suggestions
If there is only one thing you take away from this article, make it this step. Disabling the built-in Windows tips feature fixes the Runtime Broker high CPU bug for about 90% of users. It is an incredibly easy tweak.
How to do it in Windows 11 and 10:
- Press the Windows Key + I on your keyboard to instantly open the Settings app.
- Click on System on the left-hand menu.
- Select Notifications from the list on the right.
- Scroll all the way down to the bottom of the notification settings.
- Uncheck the boxes that say "Get tips, tricks, and suggestions as you use Windows" and "Offer suggestions on how I can set up my device."
Once you uncheck those boxes, press "Ctrl + Shift + Esc" to open Task Manager. Wait about ten seconds. You should literally watch the Runtime Broker CPU usage plummet back down to zero.

2. Kill the Process and Let It Reboot
Have you ever tried dealing with a stubborn piece of electronics by just unplugging it and plugging it back in? That logic applies to background processes, too.
If disabling the tips didn't work, Runtime Broker might just be caught in a temporary glitch. You can safely force it to shut down.
Here is the exact process:
- Right-click on your Taskbar (or the Start button in Windows 11) and select Task Manager.
- Make sure you are on the Processes tab.
- Scroll down until you find Runtime Broker.
- Right-click on it and select End Task.
Your screen will not go black, and your computer will not crash. Because it is a core Windows process, the operating system will simply wait a few seconds and automatically restart a fresh, glitch-free version of Runtime Broker in the background.
3. Hunt Down the Problematic UWP App
If you killed the task and it immediately comes back eating 30% of your CPU, you have a bad app running in the background. One of your Microsoft Store apps is aggressively spamming the broker for permissions.
We need to restrict your background apps to find the culprit.
How to stop background apps in Windows:
- Open the Settings app (Windows Key + I).
- Go to the Apps section and click on Installed apps.
- Look for apps you recently downloaded from the Microsoft Store, or built-in apps you never use (like the Xbox app, Cortana, or Your Phone).
- Click the three dots next to the app, select Advanced options, and under "Background apps permissions," change the setting to Never.
By stopping these apps from running silently in the background, you cut off their ability to bother Runtime Broker. It is a bit of a trial-and-error process, but it works wonders for system performance.
Is Runtime Broker a Virus? (And How to Check)
Because Runtime Broker has a scary-sounding name and causes severe performance drops, people constantly assume it is a virus or a crypto-miner.
Let me be perfectly clear: the official RuntimeBroker.exe is not a virus. It is a vital Microsoft component.
However, hackers and malware developers are incredibly sneaky. They know you are likely to ignore a process if it has a legitimate-sounding name. Sometimes, they will disguise a Trojan or a crypto-mining script by renaming their malicious file to "RuntimeBroker.exe" in hopes that you will leave it alone.
Luckily, there is an incredibly simple trick to find out if the process running on your PC is the real deal or a clever imposter.
How to verify the file:
- Open Task Manager (Ctrl + Shift + Esc).
- Find Runtime Broker in the list, right-click on it, and select Open file location.
- Windows will open a File Explorer window showing you exactly where that specific file lives on your hard drive.
If the folder that opens is C:\Windows\System32, you are completely safe. That is the heavily guarded core of the Windows operating system, and the file is legitimate.
But, if it opens a random folder in your AppData directory, your Downloads folder, or some weird hidden directory on your desktop, you have a massive problem. That is malware wearing a fake mustache. You need to run a full system scan with Windows Defender or Malwarebytes immediately.

Can You Disable or Delete Runtime Broker Permanently?
When people get frustrated with high CPU usage, their first instinct is to find the file and delete it permanently. I see this question on tech forums every single day: "How do I permanently disable Runtime Broker?"
Here is my expert advice: Don't do it.
If you go into your Registry Editor and force-disable Runtime Broker, or if you manage to bypass system protections and delete the executable file, you will severely break your operating system.
Remember our bouncer metaphor? If you fire the bouncer, the club doesn't just let everyone in for free. The club simply closes its doors.
Without Runtime Broker running, none of your Universal Windows apps will launch. The Microsoft Store will crash. The built-in Calculator will refuse to open. The Windows Photos app will fail to load your pictures. It will cause a cascading failure across your entire daily workflow.
Instead of trying to aggressively delete a core component of your operating system, just use the notification and background app fixes we discussed above. Treat the symptom, do not kill the patient.

Final Verdict
At the end of the day, Windows is an incredibly complex machine with millions of moving parts. Sometimes, those parts bump into each other and cause a little friction.
Runtime Broker is one of the unsung heroes of your computer's security infrastructure. Yes, it can be annoying when the "Windows Tips" bug causes it to temporarily turn your laptop into a space heater. But without it, your private data, your webcam, and your microphone would be completely vulnerable to any shady app you accidentally download.
Next time you see it sitting in your Task Manager, you don't need to panic. You know exactly what it is, exactly what it is doing, and exactly how to put it back to sleep.
