There is also description what it does (it changes the number allowed of half-open connection from 10 to 50)

Number of half-opened connection is set defaultly to 10 (win xp) since SP2 (also some later updates that replaced file tcpip.sys and so changing the default value back to 10)

Hi, remember the values is not for the total amount of connections : it it the amount of new connections per second. People always forget this.

Patching a system file like TCPIP.SYS is a malware behaviour, and can be flagged by other programs that use integrity checking.
