svchost.exe is a system process that hosts and manages Windows services running from DLL files rather than standalone executable files, allowing Windows to modularize and efficiently manage background tasks.
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 Background Discovery Broker is a relatively new service, introduced in Windows 10 version 1903, and its purpose is to make it easier for apps to find and connect to devices, such as Bluetooth devices, printers, and scanners.
The DevQueryBroker service works by running a background task that periodically scans for devices. When it finds a new device, it sends a notification to all apps that have registered for device discovery events. This allows apps to quickly discover new devices without having to continuously scan for them themselves.
If you are having problems with an app that is trying to discover a device, you can try restarting the DevQueryBroker service.
Windows Service Startup Type:
In Microsoft Windows, Windows services can be configured with different startup types that determine how and when they are started:
- Automatic: The service starts automatically when Windows boots.
- Automatic (Delayed Start): The service starts automatically after the system has finished booting and initial services have started, helping improve startup performance.
- Manual: The service does not start automatically. It must be started by a user or another process when needed.
- Manual (Trigger Start): The service starts manually or in response to specific system events (triggers), such as device insertion or network changes.
- Disabled: The service is prevented from starting, even if required by the system or an application.
