netsh interface tcp show supplemental
10 이다.
2 Create Window Settings Template
netsh interface tcp set supplemental template=custom icw=46

netsh interface tcp set supplemental template=custom

however it does not work in Windows 8.1, or Windows 10 workstation variants (read-only setting error).
To set using Powershell cmdlets (only available in server variants):
Set-NetTCPSetting -SettingName InternetCustom -InitialCongestionWindow 10
