Not all services need to run 24/7. Trimming the fat can slash Windows 11 Service Host load.
| Service Name |
Why Disable? |
How to Disable |
| SysMain (Superfetch) |
Preloads apps but spikes CPU on SSDs |
services.msc > SysMain > Properties > Startup type: Disabled |
| Windows Search |
Indexes files, causing network pings |
services.msc > Windows Search > Disabled (if you rarely search) |
| Background Intelligent Transfer Service (BITS) |
Handles updates; overloads network |
services.msc > BITS > Manual (not Disabled, to keep updates working) |

High network usage often ties to misconfigurations. Tweak these for smoother sailing.
- Reset TCP/IP: In admin Command Prompt, run
netsh int ip reset and netsh winsock reset. Restart your PC.
- Limit Background Data: Settings > Privacy & security > App permissions > Background apps. Turn off for non-essentials like Cortana or Xbox services.
- Power Plan Adjustment: Search for "Power & sleep settings" > Additional power settings > Change plan settings > Change advanced > Processor power management > Set max to 99% to curb idle spikes.
These tweaks reduce Service Host Network high usage by curbing unnecessary polling. Test your internet speed post-fix to feel the difference!
