XP SP2 how to achieve multi-threaded access

Although Microsoft has limited the maximum secure connection limit to 10 threads in Windows XP SP2, this is definitely not enough for the majority of BT enthusiasts and friends who often use multi-network software to network. I found a software on the Internet that can modify the maximum security connection limit of Windows XP SP2 system file Tcpip.sys, you can download it at www.lvllord.de/?url=downloads&lang=en, only 30KB. After downloading, put this file in the system directory, then enter DOS mode, run EvID4226Patch/l=$n$/w=C:\\WINDOWS\\system32\\drivers/l=tcpip.sys, where $n$ is Personal needs to be set, if the author needs to set the maximum security connection limit to 50 threads, then enter EvID4226Patch/l=50/w=C:\\Windows\\system32\\drivers/l=tcpip.sys, I do not recommend This value is changed too high, so the network security will be greatly reduced. I recommend that the average user set to 10 to 30, the BT enthusiast set to 100 to 150, and install anti-virus software and firewall, so that network security is guaranteed.
