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 Portable Device Enumerator Service (WPDBusEnum) is a Windows service that detects and manages communication with portable devices like smartphones, tablets, digital cameras, and media players. It supports protocols such as Media Transfer Protocol (MTP) and Picture Transfer Protocol (PTP), allowing these devices to appear in File Explorer and enabling file transfers, media syncing, and AutoPlay functionality. The service runs automatically when a compatible device is connected and is essential for proper interaction with devices like Android phones or digital cameras.
If disabled, Windows may fail to recognize portable devices, preventing file transfers and syncing through applications like Windows Media Player or Photos. However, the service has minimal impact on system performance since it only activates when a supported device is connected. Most users should leave it enabled unless they never use external media devices.
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.
