Modify registry to accelerate Internet access

I checked the registry in the library a few days ago and found it quite useful. Share with you.

The following are the changes to speed up the Internet, but if the bandwidth is not good, it is in vain.

 

Run regedit to open registry manager. Then, locate HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters in the following path.

Right-click the blank area on the right of the parameters subkey, select "new"> "DWORD Value", and name it "defaultttl". Then, right-click and select "modify". In the displayed window, change the value to "80" (hexadecimal) or 128 (decimal ).

Create the following "DWORD Value" in sequence and modify its value (if there are two values, the former is hexadecimal, and the latter is decimal ):

"Enablepmtubhdetect" = "0"

"Enablepmtudiscovery" = "1"

"Globalmaxtcpwindowsize" = "7fff" or "32767"

"Tcpmaxdupacks" = "2"

"Sackopts" = "1"

"Tcp1323opts" = "1"

"Tcpwindowsize" = "7fff" or "32767" (93440 or 186880 or 372300, depending on network conditions)

Save the changes and restart your computer.
