About this tag
TCPView is a Sysinternals utility for monitoring TCP and UDP endpoints on Windows. Discussions on WindowsForum.com show it used to identify which processes maintain network connections, especially when troubleshooting unexplained bandwidth usage. Users pair TCPView with Process Explorer and Resource Monitor to trace high network activity back to specific processes, such as svchost.exe. The tool helps diagnose issues like persistent connections after closing applications or services. While TCPView provides real-time endpoint visibility, advanced users also rely on built-in tools like netstat, PowerShell cmdlets (Get-NetTCPConnection), and Resource Monitor for deeper analysis on Windows Server and desktop editions.

It would appear that it's like the videos are still running but they are not because the site and anything to do with it is shutdown. Not even a browser is running. Task manager tells...
