In Microsoft Windows, corruption of the WinSock installation can cause network connections to fail on computers running the Windows operating system. This corruption sometimes occurs when you uninstall software applications that rely on WinSock. These applications include adware/spyware systems, software firewalls, and other Internet-aware programs.

To fix WinSock corruption problems, follow either of the two methods described below.

Instructions in this article apply to Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista, and Windows XP SP2.

Fix WinSock2 Corruption

For Windows systems, Microsoft recommends following a specific manual procedure to recover from WinSock network issues caused by corruption. The procedure varies depending on which version of Windows you have installed.

With Windows 10 to XP SP2, the netsh administrative command-line program can repair WinSock.

For older Windows XP installations without XP SP2 installed, the procedure requires two steps:

  • modifying the related Windows Registry keys
  • re-installing the TCP/IP protocol
