Windows Sockets or Winsock is a technical specification or a programming interface which decides how any program handles input/output requests for Internet applications, i.e., TCP/IP in Windows. In this guide, we will learn about Winsock, why and when you need to reset, and how to reset Winsock in Windows 10.

What is Winsock

Like we said that it’s a programming interface. Windows 10 carries a DLL with name winsock.dll that implements the API and coordinates Windows programs and TCP/IP connections. The settings contain computer configuration for internet connection.

When do you need to reset Winsock

Sometimes Windows Sockets or Winsock may get corrupt as a result of which you may not be able to connect to the Internet. The error can occur when you download an unknown file which has a malicious script. These scripts can partially block Winsock, blocking your internet connection. If you have trouble opening websites, it could be due to corrupted Winsock settings.

If you receive any of the following or some similar error message, it means you need to reset Winsock:

  • An error occurred while renewing interface ‘Internet’: An operation was attempted on something that is not a socket.
  • An error occurred while renewing interface Local Area Connection: the requested service provider could not be loaded or initialized.
  • An error occurred while renewing interface local area connection: an operation was attempted on something that is not a socket. Unable to contact driver Error code 2.
  • The operation failed since no adapter is in the state permissible for this operation.

How to reset Winsock in Windows 10

Before you go ahead and reset Winsock, do remember to create a system restore point first.

Next, open Command Prompt as administrator and type the following command and hit enter.

netsh winsock reset

As an admin, you can also generate a log file of the changes. To append a log file path to the above command:

netsh winsock reset c:\winsocklog.txt

Wait for the Command Prompt to run through the reset. Now, you will have to restart your computer to see the effects.

What happens when you reset Winsock

When you execute the command, it fixes any corruption that has occurred with the DLL file. So there is no fix except to replace it with a new copy of Winsock and bring it back to the default settings.
