- The symptoms exist due to the new re-written TCP stack introduced since Windows Vista that aims to take full advantage of hardware advances such as gigabit networking. Among the new feature in Windows TCP/IP is Receive Window Auto-Tuning Level for TCP connections.
- Windows (Vista/7/8/etc) will automatically set - and more importantly, increase - the size of the TCP receive window for you, as needed, to maximize throughput. Receive Window Auto-Tuning: Microsoft calls this automatic management of the receive window size 'auto-tuning'. To see the settings associated with this, go into a DOS prompt and run.

Aug 12, 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. Receive Window Auto-Tuning Level: disabled Otherwise TCP Window Scaling is disabled not only for receiving but also for sending which will significantly limit the connection speed. To enable TCP Window Scaling set Auto-Tuning level for example to normal: netsh interface tcp set global autotuninglevel=normal. 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 17, 2016 Window Auto-Tuning is a networking feature that has been part of Windows 10 and previous versions for many years. It’s designed to dynamically control the receive throughput buffer size and latency of a link.
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 10 too. In today’s Internet, the range of latencies & throughput speeds is just too large to manage statically. It needs to be adjusted dynamically. Windows 10 will dynamically adjust the receive buffer size to the throughput and latency of the link, using this feature.
Programs like Automatic Updates, Windows Update, Remote Desktop Connection, Windows Explorer for network file copy, etc, use WinHTTP or Windows HTTP Services.
Receive Window Auto Tuning Level Windows 10
Window Auto-Tuning feature is enabled by default in Windows 10 and makes data transfers over networks more efficient. But if your network uses an old router or your firewall software does not support this feature, then you may experience slow data transfers or even loss of connectivity.
To check the status of Auto-Tuning feature on your system, in an elevated command prompt windows, type the following and hit Enter:

If you see ‘normal’ written against Receive Window Auto-Tuning Level, it means that the feature is enabled and it is working fine.
To disable Windows AutoTuning, run the following command:
I have upgraded to Windows 10 Pro using a USB stick from Windows 8.1. Apple did not respond to the problem. Mac mini 2006 boot camp windows 7. Bootcamp did not support installation of Windows 10. Have it repair the installation, it will create this partition pointing to Windows.The drivers are difficult to find, however, you can buy a Mac and do everything needed in Windows without having to have any apple software loaded on the machine.
To enable Windows AutoTuning, run the following command:
You can also tweak the Windows Registry, says KB947239. To enable the Receive Window Auto-Tuning feature for HTTP traffic, Run regedit and navigate to the following registry subkey:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionInternet SettingsWinHttp
What Is Receive Window Auto Tuning Level Windows 10
Right-click on it > New > DWORD Value. Type TcpAutotuning and give it a vale of 1.
Click OK and exit.
To disable Receive Window Auto-Tuning feature for HTTP traffic, give it a value of 0 or delete the created TcpAutotuning DWORD.
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.
Let the default settings of Window Auto-Tuning feature be enabled. If your network uses an old router or your firewall software does not support this feature, and you are experiencing poor or no connectivity issues, only then may you disable this feature and see if it works in your favor.
