TCP-Z

TCP-Z is a powerful, freeware tool designed to optimize system performance by removing or increasing the limit of half-open TCP connections in Windows 7. Developed by deepxw, this program belongs to the System Utilities category, specifically under the System Optimization subcategory. The latest version, 2.6.2.75, allows users to enhance network speed, download faster, and run multiple tasks simultaneously.

One of the key features of TCP-Z is its ability to perform the Event ID 4226 Patcher fix, also known as the EvID4226 Fix or the TCP/IP Patch. This functionality helps to address the TCP Half Open Connection Limit issue, effectively maximizing the efficiency of your internet connection.

The program itself is highly efficient with minimal resource usage, making it particularly favorable among users from countries like the United States, China, and Japan. It is worth noting that while TCP-Z supports Windows XP and earlier versions, the latest update focuses predominantly on Windows 7. The program files, notably TCPZ.exe, ensure straightforward installation and operation.

Launched with version 2.6, TCP-Z has attained significant popularity with over 74,135 downloads since its inclusion in the software catalog in 2011, with recent weekly download figures standing at 18. Despite its robust capabilities, TCP-Z maintains a relatively small footprint in comparison to other heavy software in the networking software section.
