Hi H M,
Thanks for your post. Based on my research, SACK support in Windows is controlled through Registry at:
- Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
- Value: SackOpts
- Type: REG_DWORD
- Data: 0 to disable
- Reference: Microsoft Word - NetDCU_TCPIP_ParametersConfigurableByUser.htm (fs-net.de)
Best Regards,
Ian Xue
