Windows 11 comes with a plethora of hidden services that can consume significant CPU resources, leading to sluggish performance. By disabling unnecessary services, you can give your CPU a much-needed break. Here's how to do it:

Disable the Windows Runtime Broker
The Windows Runtime Broker manages permissions for Microsoft Store apps. It should consume around 20-30% CPU at most, but it can spike unexpectedly. To disable it:
- Open Task Manager by pressing the Windows key + R.
- Go to the Processes tab.
- Find and close the Runtime Broker process.
- If you don't use the Microsoft Store, this service won't kick in automatically.
- Disabling this service can save you a significant amount of CPU resources.
Disable the Windows Search Indexer
The Windows Search Indexer runs in the background to maintain an updated searchable index of files, documents, images, videos, and emails. While it helps with file searches, it can spike CPU usage when indexing large files or repairing the underlying index. To disable it:
- Press the Windows key + R to open the Run prompt.
- Type
services.mscand press Enter. - Find the Windows Search service and click the Disable button.
- If you want to disable it permanently, select the Disabled option in the Startup type dropdown.
Disable Windows Defender's Background Scans
The Antimalware Service Executable (MsMpEng.exe) is the Windows Security service that scans your PC in real-time for threats. It can consume up to 50% of your CPU when scanning large files or folders. To disable it:
- Open Windows Security.
- Click on Virus & threat protection.
- Under Virus & threat protection settings, click Manage settings.
- Disable the Real-time protection slider.
Disable the Text Input Helper
A text input helper running in the background can also consume CPU resources. To disable it:
- Press the Windows key + R to open the Run prompt.
- Type
services.mscand press Enter. - Find the Text Input Helper service and click the Disable button.
By disabling these unnecessary services, you can give your CPU a much-needed rest and improve your system's overall performance.
