Windows 10 have an auto-tuning feature which tries to dynamically adjust the receive buffer size for transmission and latency of the link. In-fact this feature is present in all Modern Operating systems including Windows 10. So, its a Necessary Feature all together as it manages and adjusts Receive buffer size dynamically.
Aug 13, 2016 Like all modern operating systems Windows has receive window auto-tuning to dynamically adjust the receive buffer size to the throughput and latency of the link. Disabling this feature will definitely limit your Internet speeds. Auto-tuning is consistent throughout all variants of TCP and present in all modern operating systems. Try enabling 'experimental' mode for astronomical Auto-Tuning levels. When setting Windows Auto-Tuning level the possible settings are as follows: normal: default value, allows the receive window to grow to accommodate most conditions; disabled: uses a fixed value for the tcp receive window. Limits it to 64KB (limited at 65535). If required, restrict the Windows TCP receive side scaling auto tuning level: C: netsh interface tcp set global. Note: If the hotfix KB958015 is not applied, the autotuning level must be set to disabled rather than highlyrestricted, and that is the reason of the difference of NPG and the Powerlink article.
