I am uncertain about the more modern Windows OS like 8.1 and Server 2012. However, auto-tuning did not work correctly in Windows 7 and Server 2008 R2. One of the biggest symptoms was that GUI-based copy/paste between Windows 7 workstations and Server 2008 R2 servers would fail or creep along very slowly (think of copying a file to the company share or your home drive). Disabling auto-tuning, receive-side scaling, and heuristics almost eliminated the issue for me. If your environment consists of these particular operating systems, then you will want to disable auto-tuning, receive side scaling, and heuristics on both the workstations and servers. There is a hotfix but it may be just as easy to either script it or do it manually.

It is an easy fix and won't interrupt production.

Tcp Autotuning Windows 10

Windows Vista includes a feature, “Receive Window Auto-Tuning,” that you’ve likely never seen mentioned on your desktop, but which can cause noticeable drag and even crashing when browsing certain web sites or using some routers or other network hardware. If you’re noticing browsing glitches that only occur in Vista, the Wise Bread blog has a tip, pulled from PC Magazine’s recent issue, that explains how to turn off auto-tuning and skip the spinning blue circle of death.

To determine you current settings launch a command prompt as an Administrator (type “cmd” into the Start box, right-click on Command Prompt and select “Run as Administrator), then enter the following line:

Disable Windows Auto Tuning Level

If the line Receive Window Auto-Tuning Level does not say disabled, enter this command:

Disable Autotuning Windows 10

netsh interface tcp set global autotuning=restricted

If that doesn’t help the simplest way to turn off auto-tuning is to enter the following line:

netsh interface tcp set global autotuning=disable

That should do it, and turning it off won’t likely have any adverse consequences. You should notice the difference in browsing speeds immediately. If you find otherwise, turn it back on with:
