Hack Attack : Hack Vista to Browse at High Speeds
photo credit: jpctalbot
I’m not a Windows Vista fan, but even then everyone at my home uses Windows Vista, while I dual boot with OSX on my Hackintosh.. I’ve used XP before and for some reason I always felt that Internet speeds on Vista were comparably slower than on OSX, and more so even Windows XP.
Considering it was quite slower than what I used to get on XP, I realized that Vista was doing something extra that made my internet connection slow down. After a bit of investigation and a bit of googling I found the solution.
Before I give the solution, let me explain the problem in a bit more detail… It all comes down to Vista’s “Auto Tuning” feature. Turns out that this feature isn’t compatible with many routers and networking devices(including mine). Means the feature that was supposed to be a boon turned itself into some sort of a bane.
Anyways here’s what you need to do turn off the Auto Tuning feature on Vista..
At the Start menu type command, but don’t launch the command prompt immediately. Instead, right-click it and choose Run As Administrator. Once the prompt is open enter the following command.
netsh interface tcp show global
If the line Receive Window Auto-Tuning Level does not say “disabled,” enter this command:
netsh interface tcp set global autotuning=restricted
If this doesn’t help, substitute this command and see if it works
netsh interface tcp set global autotuning=disabled
At this moment, you should notice considerable improvements in your browsing speeds, or rather you should be cruising now. If it works, you should notice the difference in browsing speeds immediately. If it doesn’t work for you, and you feel the need to put things back the way they were, you can type this command:
netsh interface tcp set global autotuning=normal
Here are screenshots showing the whole process, incase you feel the need for it..
Good luck, hope this works for you.. Please let us know if this worked for you or not..

Where is the donate button? Seriously.
This worked amazingly. I hadn’t even realised how dampened my browsing speeds were until this. My browsing speeds have been cut in half, at least.

Very cool. And we thought FireFox was the only browser with tricks up it’s sleeves.

Thankyou I have a vista laptop and a dual boot osx vista desktop…this was amazing how is this not a widely known hack? Is there any negative effects of doing this?
I chose the disabled command because I felt like it.

im not sure if this has worked for me ……… i have not been on your site for a week and im a fire fox user so i used your firefox hack at the same time as doing this and my internet speeds have boosted so im buzzing im not sure if its one or the other or both but something has worked
Cheers mate

This “hack” is best/only for Vista RTM, MS updated TCP/IP and networking etc in SP1… so my recommendation is try Vista SP1 (with/without the “hack” if you must) and see how you go.
http://dotnetwizard.net/?p=542
Or Google… vista sp1 autotuning=disabled
I’ll try this “hack” on my freshly built Vista Ultimate with SP1 (SP1 built in, new iso), but don’t expect much.
I still swear by “TCP Optimizer”, and the “webtweak”…
http://www.speedguide.net/downloads.php
And they have info on disabling autotuning…

Have fun.

I thought i would give this little Hack Attack a try on Vista Server 2008,but it alreadt set at normal. Just another reasons to convert Server 2008 into a workstation.

@IANG
If it is set to normal then that means that is turned on. You want it at disabled I think.

Vista is a Drag. I want to like it, but it’s not much better and it’s hogs up more of the system resources. Oh well. Another Great Article!

The command prompt worked for me but I don’t really notice the difference in the speed… maybe I just don’t realise it

What the Hell, It works, It really does. Eureka….
When will we be able to see a “humble” Vista workin with no need to hackin’ it??
Why Microsoft do this to us? I guess it’s just we don’t read between the lines, they want us to convert to Ubuntu.
The more I use Vista the more I miss XP, I swear if it did’t have Aero…

Hi
Half my browsing ground to a halt this morning. As did every other vista I know of around here.
This fixed it instantly.
Bizarre.
Cheers

Well, no luck. For either suggested command I get an error message:
Set global command failed on IPv4 The requested operation requires elevation.
Since I have no idea what that means, guess I’ll live with the untweaked for now.
Thanks for the info though.

this actually, actually WORKS!! i’m always suspicious whenever i stumbleupon sites which claim that downloading this, or tweaking that, or messing with this will “speed up your computer”… and i honestly don’t know why i decided to risk it this time - maybe cos you had outlined a way to change it back in case it didn’t work and maybe all the comments - but i’m so so so glad i did.
it really does bloody well work!
the difference is actually noticeable, and not just if your a tech-head, even if your just someone who surfs on and off… trust me you’ll notice the difference. sites literally just “snap” on!
well done and big thumbs up… way up!

I also got
‘Set global command failed on IPv4 The requested operation requires elevation.’
for both

it really does seem to make an improvement. I had no idea that it was the computer, I just assumed it was my DSL connection that seemed slower. Many thanks!

Help. When I attempted to right click on command in start I didn’t get the option to run as administrator. What now?

Alfred
I used this and my download speeds remained broadly static. I guess I’m just lucky with my router?
Dec 10th, 2008
Michael
hmmm. no real difference here:
up/down on speed test:
normal = 9126/612
restricted = 9190/610
normal = 9211/612
not enough to tell if it was traffic at the time of the test or due to the settings. back to normal for me.

Does absolutely nothing here.

Wow, worked wonders. My already moderately fast connection is much smoother.

“netsh interface tcp show global” gives this result.
TCP Global Parameters
———————————————-
Receive-Side Scaling State : enabled
Chimney Offload State : disabled
Receive Window Auto-Tuning Level : highlyrestricted
Add-On Congestion Control Provider : none
ECN Capability : disabled
RFC 1323 Timestamps : disabled
None of the other commands worked. Command says “Set global command failed on IPv4 The requested operation requires elevation.”

NEED HELP!

Wow, worked great on my laptop!
(I used disabled, with restricted the effect wasn’t really noticeable to me)

Wow!
This worked amazingly well! Streaming and browsing speeds went through the roof!
Thanks!

I went to check this and found my hacked version of Vista (eXPerience’s TinyVista) already had this disable using yet another setting: highlyrestricted. It’d be interesting to see if this makes a difference opposed to restricted.

When I typed it in, I got the following message: Set global command failed on IPv4 The requested operation requires elevation
Has anyone else had this happen. If so, what’s stopping it.

Paul - You didn’t run cmd as administrator, did you?
