svchost.exe loads and runs Windows services, such as networking, Windows Update, audio, and many others. Multiple instances of svchost.exe can run simultaneously, each hosting different services. This helps with stability and security—if one service fails, it doesn't crash all services.

Additional Information:
The WWAN AutoConfig (WwanSvc) service manages Wireless Wide Area Network (WWAN) connections on Windows devices, including cellular data (4G/5G/LTE) via built-in mobile broadband adapters (e.g., SIM card slots). It automates the configuration, activation, and maintenance of cellular networks, enabling features like automatic carrier detection, data roaming, and connection profiles.
This service is essential for laptops, tablets, or PCs with cellular capabilities, ensuring seamless internet access on the go. If disabled, cellular connectivity will fail, though it does not impact Wi-Fi or Ethernet. Most users should leave it enabled if they use mobile data; others can safely disable it to save minimal system resources.
