The CDPUserSvc service is a critical component of the Windows operating system. As such, it is important to understand how it works and how to manage it effectively. This article provides an overview of the CDPUserSvc service and offers tips for managing it in a way that ensures optimal system performance.
Understanding the CDPUserSvc Service
The CDPUserSvc service is a part of the Connected Devices Platform Service that handles storage and synchronization of user data across devices. It is a user service that can be managed through the Services tab. If you encounter high CPU usage or errors such as “has stopped working,” try restarting the service using sc.exe stop CDPUserSvc_3e64b followed by sc.exe start CDPUserSvc_3e64b. To troubleshoot further, use Process Explorer to investigate the DLL files and handles associated with the service. The service configuration list is available in the CurrentControlSet\Services\CDPUserSvc registry key. This service is crucial for functionality of apps such as Mail and Calendar, and references to it may appear in messages or badges.
