Turn on/off TCP/IP semi-open connection limit in Windows 7

I believe we all have such experience, ordinary ADSL broadband, open the download tool to download resources, then want to browse the Web page will become very difficult, Windows7 also not spared.

The reason, on the one hand is that some download software in order to pursue the speed of the download at the expense of all the bandwidth, on the other hand, because of Microsoft security considerations, limited the system of TCP/IP half-open connection number.

And the way to remove the restrictions is simple:

* Win+r Run regedit

* Find

Hkey_local_machinesystem\currentcontrolset\services\tcpip\parameters

* Find the Enableconnectionratelimiting key value in the right panel

At this point, there are three things in total:

1. No such key value: So congratulations, your system does not have TCP/IP connection limit

2. The key value is 0: Still congratulate you, your system also does not have the TCP/IP connection number limit

3. The key value is 1:TCP/IP limit is activated, the default is 11.

The removal method is, of course, very simple:

* Double-click to modify its value of "0"

* Click OK to exit

PS: This method also applies to Vista SP2

As a result, bandwidth-intensive conditions should improve, but the root cause is to limit the download speed to solve.
