C:\WINDOWS\system32> netsh interface tcp show global
Querying active state…

TCP Global Parameters

Add-On Congestion Control Provider : default
ECN Capability : disabled

Receive Segment Coalescing State : enabled

step02. 把 Receive Window Auto-Tuning Level (接收視窗自動調整層級) 改為 Disabled .
> netsh interface tcp set global autotuninglevel=disabled

有些江湖傳言說改為 disabled會加快上網變快之類,若不熟悉者還是小心使用。
