Windows 11 Services to Disable
In the XDA Developers article ‘5 services I disabled to improve Windows performance’, the author demonstrates how turning off five unnecessary background services can free up CPU and memory, reduce disk thrashing, and speed up boot times.
Services to disable
- Windows Search: Stops file indexing to save RAM and CPU cycles
- SysMain (formerly Superfetch): Prevents redundant pre-loading of applications that can degrade SSD performance
- Delivery Optimization (Windows Update Delivery): Disables peer-to-peer sharing of update files to conserve bandwidth
- Remote Desktop Services: Turns off remote-access listeners to eliminate unused processes and reduce security risk
- Connected User Experiences and Telemetry: Stops telemetry data collection and transmission to improve privacy and cut background CPU/network usage
How to disable
- Press Windows + R, type services.msc, and press Enter.
- In the Services window, find the service you want to disable.
- Right-click it, select Properties, click Stop, set Startup type to Disabled, then click OK.
- (Delivery Optimization only) Open Settings » Windows Update » Advanced options, and turn off Delivery Optimization or restrict it to local network devices.
Restart your PC to apply changes. You can re-enable any service at any time by reversing these steps.
