The Receive Window Auto-Tuning feature lets the operating system continually monitor routing conditions such as bandwidth, network delay, and application delay. Therefore, the operating system can configure connections by scaling the TCP receive window to maximize the network performance. To determine the optimal receive window size, the Receive Window Auto-Tuning feature measures the products that delay bandwidth and the application retrieve rates. Then, the Receive Window Auto-Tuning feature adapts the receive window size of the ongoing transmission to take advantage of any unused bandwidth.
While the feature may improve speed, in some cases it can also cause problems and slow down the network.

While the feature may improve speed, in some cases it can also cause problems and slow down the network. To disable the feature, use this command: netsh interface tcp set global autotuning=disabled. To disable the Receive Window Auto-Tuning feature for HTTP traffic, follow these steps: Log on to the computer as a user who has administrative credentials. Click Start, type runas /user: localcomputername administrator cmd in the Start Search box, and then press ENTER. Sep 20, 2010 This is how you will do it: 1.Run Command Prompt as an Administrator. Enter this command: netsh interface tcp show global. Look for Receive Window Auto-Tuning Level. You will have to see what value is written there. Restart your computer and see if the problem is solved.
To disable the feature, use this command:
To see if the feature is enabled or disabled, use this command:
To enable the Receive Window Auto-Tuning Level, use this command:
Here’s a list of available options for the autotuning parameter:
disabled: Fix the receive window at its default value.
highlyrestricted: Allow the receive window to grow beyond its default value, but do so very conservatively.
restricted: Allow the receive window to grow beyond its default value, but limit such growth in some scenarios.
normal: Allow the receive window to grow to accommodate almost all scenarios.
experimental: Allow the receive window to grow to accommodate extreme scenarios. WARNING: This can dramatically degrade performance in common scenarios and should only be used for research purposes.
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.
How to Check if Auto Tuning Feature is Enabled ?
1 – Open Command Prompt as admin by Searching cmd in Windows 10 Search box and then right clicking on the cmd icon and clicking on Run as Administrator.
2 – Now, run the following command given below.
3 – In the output if Receive Windows Auto Tuning Level says Normal, then the Auto tuning Feature is enabled on your PC.
