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 User Data Access service enables apps to access structured user data, such as contact info, calendars, messages, and other content. UWP apps need this service because they run in a sandbox and cannot access the data the way desktop applications do.
If you stop or disable this service, UWP apps that use this data might not work correctly.
The User Data Access service is a per-user service, which is created when the user logs in and is stopped and deleted when the user logs off.
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.
