Recommended: disabled (to retain user-set auto-tuning level) Note this should be executed in elevated command prompt (with admin priviledges) before setting the autotuninlevel in next section. If the command is accepted by the OS you will see an 'Ok.' On a new line. TCP Auto-Tuning Disable TCP Receive Windows Auto-Tuning. 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. THE INFORMATION IN THIS ARTICLE APPLIES TO: All Windows products; DISCUSSION. Tuning Windows for TCP/IP performance isn't specific to any one Globalscape product. Rather, it depends on which version of Windows you are using. Therefore, rather than listing the various options here, please refer to the Google search results listed here, which provides relevant links with information about. Aug 13, 2016 An Update on Windows TCP AutoTuningLevel Posted: 12 Aug 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. Aug 28, 2016 Window Auto-Tuning feature is said to improve the performance for programs that receive TCP data over a network. It is nothing new. It was introduced in Windows Vista and is present in Windows.

And a bug found in Windows: It is very clear that when Windows was asked to display the current 'Receive Window Auto-Tuning Level' and Windows said 'normal' and claimed that 'is the result of Windows Scaling heuristics overriding any local/policy configuration on at least one profile'- that Windows displayed the wrong mode, and should have.
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.

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.
To disable the feature, use this command:
To see if the feature is enabled or disabled, use this command:
Receive Windows Auto-tuning Level Gpo System
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.
