What Is Winsock

Winsock is an application programming interface (API) that operates between applications such as a web browser. Belonging to the field of networking, Winsock, also known as Windows Socket, is used to describe the data within the computer that is used by programs to access a network. While it creates network protocols between different applications, it stores the settings that explain how the entities interact in the database. Any issues with network connectivity within applications are also related to Winsock, which might need resetting in such circumstances.


The database created and stored by Winsock is called the Winsock Catalog. Whenever you consider resetting Winsock under the netsh Winsock reset option, the configurations made across the Winsock Catalog will reset. The networking programs associated with the catalog will get a fresh start as they reconnect to the TCP/IP traffic with default settings.
