在XP系统中，出于安全原因Windows就限制了TCP连接数目，即并发对外TCP连接数量具有上限，这一优点也被Vista继承下来。但是，对于P2P程序来说，这种限制也同时限制了传输速度。

softpedia提供了一种方法可以修改这个限制。首先需要下载补丁文件：64位 tcpip.sys或 32位 tcpip.sys，然后在命令提示行运行以下命令：

takeown /f c:windowssystem32driverstcpip.sys
cacls c:windowssystem32driverstcpip.sys /G "username":F
注意：上面的"username"要替换为你的登陆名称，继续输入以下命令可以关闭TCP/IP自动调整功能：
netsh int tcp set global autotuninglevel=disable

对于64为Vista还要运行以下命令让驱动程序具有合法的签名：
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

接下来，将下载到的补丁文件放到C:windowssystem32drivers文件夹。找到注册表位置：
HKEY_LOCALL_MACHINE > SYSTEM > CurrentControlSet > Services > Tcpip > Parameters

新建一个"DWORD"，名为TcpNumConnections，然后双击TcpNumConnections，将其值设为你想要的最大值，重启机器即可。

注：由于这两个文件破解者把它上传到了外国空间，所以速度很慢，为了方便大家，我就把这两个文件下载了下来，并且压缩上传到了我的空间，请大家下载后将适合自己的tcpip_**.sys 改名为tcpip.sys，再按上述操作就可以了！文件在文章末尾！

Are you a hard-core peer-to-peer user? Then you are already aware of the limitations that Windows XP features when it comes to incomplete TCP connections. What you might not know is the fact

that those restrictions have transitioned into Windows Vista. The maximum level of the simultaneous incomplete outbound TCP connection attempts per second in Windows Vista is associated with the editions of the operating system.

The Windows XP SP2 and Vista TCP connection attempts limitations are focused on improving security, but an immediate downside is the fact that it impacts BitTorrent applications. Heavy users of P-2-P networks will find that their transfers will be slowed down. Fortunately, there is a workaround.

However, and this will also act as a disclaimer, while I will provide you with a tutorial to bypass the TCP limitations and also point you in the direction of two patches, I advise you to exercise caution when performing the process. Otherwise, neither I nor Softpedia are responsible of the way you choose to use P-2-P networks and applications.

Right, with this out of the way, you will first of all need to download the patched tcpip.sys: 64-bit tcpip.sys or 32-bit tcpip.sys. Then simply launch command prompt and enter the commands below:

takeown /f c:windowssystem32driverstcpip.sys
cacls c:windowssystem32driverstcpip.sys /G “username”:F

Make sure that you replace “username” with the actual username you use for logon. In the command prompt you will have to enter: netsh int tcp set global autotuninglevel=disable in order to turn off the TCP/IP auto-tunning capabilities.

The bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS command is a must for 64-bit Windows Vista editions. X64 Vista features integrity checks, meaning that drivers need to present legitimate signatures.

Next you will have to make your way to the C:windowssystem32drivers folder and replace the tcpip.sys with the patched file that you downloaded in the beginning. Navigate via regedit to HKEY_LOCALL_MACHINE > SYSTEM > CurrentControlSet > Services > Tcpip > Parameters registry key. Here simply enter TcpNumConnections as a new “DWORD value.” All you are left to do now is to double click TcpNumConnections and set whatever value you wish, also setting the maximum limit of TCP/IP connections. Make sure to restart you machine.
