Since last one and half year, I have been working on Windows 7 Operating system and in my experience “Auto Tuning” in windows 7/vista/windows 2008 R2 is the most possible culprit for any network related problems. If you see a network related problem in these operating systems and cannot determine what is the cause, I suggest you try disabling “auto tuning” first.

I know that “auto tuning” is one of the features introduced with windows 7/vista to improve OS operations on network. Basically what it does is, it adjusts the TCP window size to improve the network operations. Though it sounds good in theory, I have seen numerous amount of posts over internet where disabling “auto tuning” addressed many issues like, slow data copy, slowness in email delivery, slow outlook mail caching times, and a few application data transfer related issues. Most of these issues you will see when performing the transfer operations over a WAN link.

So, considering above all, I would like to share the procedure for disabling/enabling “Auto Tuning” in windows 7 environment which may come handy for you in troubleshooting network related issues…

Procedure:

I've installed Windows 7 32-bit, using Boot Camp and everything works fine except there is an issue with Time. Every time i switch from Mac OS to Windows 7 & vice-versa the Time is displayed incorrectly, while not connected to the internet. While I'm online things are fine as the clocks update eventually. Mac boot camp clock problem windows 7 free. If you live on the west cost of North America, you will notice the hour is off by 7 to 8 hours, depending on where you are. This is because in Mac and most Linux they use GMT time where as in Windows they use something else, so every time when your Mac reboots into Windows it tries to convert the value from GMT. How to Fix Windows To Display Correct Clock. Go launch Windows regedit.exe. Right-click in Windows with Boot Camp on Mac. In Windows on your Mac, you can do a secondary click, or right-click, using an Apple Mouse, Magic Mouse, or trackpad. Apple Mouse or Magic Mouse: Click the upper-right corner of the mouse. Trackpad: See Set trackpad options in Windows with Boot Camp.

Windows 10 Tcp Tuning Utility

1. Open Command prompt with elevated rights
2. Run the command netsh interface tcp set global autotuning=disabled
3. This disables the auto tuning
4. Similar to enable auto tuning back, use the command netsh interface tcp set global autotuningl=normal

If you want to see the current status of auto tuning, use netsh interface tcp show global

Hope this helps you.
