由下载撰写的日志

由于内存只有1.5G，在Vista下开多了程序（QQ,IE,TTPlayer，MPC,BT）之后就只有不到100MB的空间了，此时系统速度严重下降，有时候音乐都有点卡~~！当然这与我的CPU有一定的关系（偶滴CPU还是P4 2.8），但主要原因还是内存不够，在网上找了一下，发现了SmartRAM 这一款内存释放软件，用了之后效果明显，从90%的利用率降低到了60%左右，在XP上同样有用！而且效果更加明显！从30%降到了10%左右，而且运行后自动隐藏在后台，悄无声息，更可贵的是他还是一款绿色软件，解压后只有一个文件，点击就可以运行！推荐大家使用！

软件说明：
1.采用高速智能释放技术，在3秒内不读写硬盘的情况下释放系统内存资源，挖掘系统潜能，保证系统长时间稳定高效运行。

2.支持随Windows启动后台运行，多个系统探针自动分析释放内存条件，4.0 版本支持 Vista 操作系统深度释放，全新释放引擎完全兼容微软最新 Windows Vista 操作系统。

3.软件内置的“智能音速关机”功能，瞬间安全地关闭 Windows 操作系统，让关机、重启不再等待支持系统随时关闭显示器，进入屏幕保护状态，无等待进入显示器节能模式。

4.软件提供系统 CD/DVD-ROM 光驱舱门打开、关闭管理功能,方便用户管理外部光存储设备。

5.增强型的释放算法,主动释放内存碎片，是数据排列更紧密，数据存储更高效、无等待延时

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:windowssystem32drivers cpip.sys
cacls c:windowssystem32drivers cpip.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:windowssystem32drivers cpip.sys
cacls c:windowssystem32drivers cpip.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.
