Windows comes with a lot of extra accessories, and if your PC is not equipped to handle overhead, you will find that your CPU is being hogged by hidden Windows services. Not all of all these services are important, however, which means that you can close some of them and give some breathing chambers to your CPU.
1
Runtime Broker
Windows manages permissions for the Microsoft Store app in the runtime broker background. The service is only about 20 to 30 percent of the CPU consumed, but it often spikes in use. These irregular spikes can be triggered by a store app you are using, or a background that may request permissions.
In any case, it can slow down your PC for a few seconds and is annoying when repeatedly. If you do not have enough RAM, it can also hang your system at the point where you will need to hard reset it.
Unless you are using any store app, disabling the runtime broker should not have any effect on the use of your Windows and you should save a good part of CPU resources.
To disable the runtime broker, fire to the task manager, head Procedures Tab, find and close and close Runtime Broker Process. It should not automatically kick until the Microsoft Store or related app is opened.
It is often triggered by Windows tips and notifications, so disabling them will lead to a long way to debate your Windows 11 PC.

Windows Search Index
As the name suggests, the Windows Search Indexer runs in the background to maintain the update, the updated, the updated index of files, documents, pictures, videos and emails stored on your PC. Therefore, when you help massively in search of a lost file, it increases the CPU use when acting large files or repairing the underlying index.
If you do not have enough CPU headroom, this service alone can slow down the windows. As long as you are constantly searching for files, I recommend to disable the service by following these steps:
-
Press Windows Key + R To open run Ready.
-
Type Service And enter.
-
Search and double-click Windows search Service.
-
Click Disabled Button to close service. If you want to disable service permanently, then choose disabled Options in Startup type drop down.
Note that this file will slow down the file search in the explorer. However, you must be good to go until you are constantly searching for files on your PC.

Statue
Antimware service is executable, or msmpeng.exe, Windows Security Service that runs continuously in the background and scan your PC in real time for any danger. However, it sometimes goes to scan large files or folders, which can increase CPU use.
If you found a lot of large files stored on your system, Windows Search Indexer and Antimaleware Service can consume more than 50% of your CPU.
You can disable service, yes, but it leaves you open to virus and malware infections. You can temporarily disable it with the task manager, but this process will recover soon instead of later. To permanently disable it, you have to disable real -time security in Windows security:
-
Open Windows Security and Click Virus and danger protection,
-
Under Virus and Danger Security SettingsClick Manage settings.
-
Disable Real time conservation Slider.
I do not recommend to do so. Personally, I will slow down my PC to Windows Safety, as it leaves open to malware. But if you are squeezed for CPU use, you can try to disable Windows security and try other free antivirus solutions that can consume less resources. Another option will have to schedule scan manually during off-hours, so Windows Security does not run a background scan in the middle of your working day.

CTF loader
CTF loader supports alternative text input methods such as speech and handwriting recognition. If you do not use the features, you are wasting CPU resources on this process, which moves continuously in the background.
Disable CTF loader, or ctfmon.exeCan be a bit difficult. You can close the process from the task manager, but it can automatically trigger and start running again. A more permanent solution is to disable service through Windows services.
-
Press Windows Key + R To open run Ready.
-
Type Service And enter.
-
Search and double-click Text input Management Service,
-
Click Disabled Button to close service. If you want to disable service permanently, then choose disabled Options in Startup type drop down.
If you are using a touchscreen laptop, disabled CTF loader may affect your on-screen keyboard. Additionally, any stylus input or trackpad options can also stop working.

Microsoft Store Background Apps
In this default form, Windows comes with a tonne blotware installed. Many of these are Microsoft Store apps, such as outlook, teams, coopillots, and more, which you cannot use daily. However, these apps are capable out of all boxes and will continue to run in the background and consume system resources.

You should now uninstall these 5 Windows apps
You will definitely not miss these apps!
The best way to deal with this is to directly uninstall all these apps. If you need refresher, we have covered a lot of ways to uninstall the software on Windows 11. If you keep them, you may disable them by following these steps and starting them automatically:
-
Open and click the task manager Startup apps,
-
Find apps you want to disable, click and choose Disabled From the top to the right.
Alternatively, you can follow these steps to disable these apps from walking in the background:
-
Open and click Windows Settings Apps,
-
Click Installed apps,
-
Click on three dots next to the Microsoft Store app you want to disable and click advanced options.
-
Under Background app permissionsSet Let this app run in the background Fall Never,
In this way, apps will be installed and will be ready for you when you are used sometime, but they are not enough to walk in the background all the time. All related procedures will start when you start the app manually.
Windows 11 may look hard on your CPU, but a lot is going on under the hood, not all of which are useful. Disabled by some background services and other twicex can give you additional hardware resources that you need to enjoy using Windows.
