Half-Open Limit Fix (short for HOLF) is free and effective patch from Russia specially designed for removing the maximum connection limitation of TCP/IP half-open. In consequence, it will effectively improve the concurrence ability of network packets (sending, receiving), and accelerate the transfer speed of multiple packets or small packet (to a certain extent, reduce the network delay).

Half-open limit fix is the most mature one in technology, and much safer to use – because it direct effects on the tcpip.sys system file to increase the number of maximum connections. Anyway, I guess a lot of users are still using the early Windows (especially Windows XP), so Half-open limit fix still has its place!

// Supported OS //

  • Windows XP SP1 (x64)/SP2 (x86,x64)/SP3
  • Windows Vista without SP (x86,x64) and with SP1 (x86,x64)
  • Windows 7 beta (x86,x64)
  • Support any language Windows

*** For Windows 7 SP1 and higher OS, this patch is not required at all, because these Windows versions have no limit of half-open connections quantity any more.

// Simple Tutorial //

  1. Run Half-open limit fix
  2. Choose a new limit of concurrent half-open outbound connections quantity and press “Add to tcpip.sys” (for most Internet users, changing the limit to 100 will be more than sufficient)
  3. Restart computer and enjoy
