How to Increase Download Speed in Windows 7/8/Vista

Filed in » Speed UpSubmitted by

If you are experiencing a slow down in browsing or download speed while surfing the web or downloading files from the internet, you may want to try applying tweaks in this post about how to increase download speed in Windows 7/8/Vista.

Before we begin, let us explain what we meant by a “slow down”. If you feel that your internet download speed is not as fast as before especially after upgrading to Windows Vista, or after a major event happened in your computer, you can call that a slow down.

If you just have the thoughts that your internet is slower than that of your friends or neighbors, well, it can be other reason which you most likely can’t do anything about it. If your internet speed is bottle-necked or capped by your ISP (internet service provider) as to match the maximum bandwidth allowed in your internet package, you can either pay more to get faster or change to a better ISP.

If you are experiencing a slow down only in some certain websites, in most cases, it is the websites that should be blamed, not yours.

If you are experiencing lagness while playing online games (mmorpg, moba, etc), it’s most likely that you are too further away from the server which gives you a high latency in which case there’s nothing you can do about it.

Well, if none of the above match your case, you can continue with the tweaks below.

How to Increase Download Speed in Windows 7 8 Vista

Clean Junks, Remove Addons and Plugins, Check for Viruses

Ironically, this can be annoying that you have to see this over and over again in other websites that are talking about the same topic relating to speed up tips around the internet. Well, it is still true that the most common causes of a internet browsing and download speed slow down are either you have too much addons or plugins in your browser that take away your bandwidth, viruses hiding behind your computer system files that continuously running in the background which hogging away your internet speed, or junks files that always have been problems to your computer. So let’s clean them one by one.

I’m pretty sure we don’t have to teach you about virus scanning. You can use any of the antivirus software to check your computer for viruses. We recommend Avast Free Protection.

As for junks, addons and plugins, you can use certain tools such as the very much popular CCleaner (Google it) or Baidu PC Faster to one-click wipe out the junks from your computer. Trust me, you will be surprised for how much junks you have in your computer. Some can be deadly though.

How to Increase Download Speed – Tweaks for Windows 7 or Vista only

The below tweaks are among the most commonly used and spread across the forums and are originally intended for only Windows Vista. We have not personally tried it on Windows 7 and thus it may not work if you are on a Windows 7 machine. Please proceed at your own risk.

  1. Open Internet Explorer.
  2. Click on Tools and then select Internet Options.
  3. Click on Advanced tab.
  4. From the settings, scroll all the way to the bottom.
  5. Check the box of Use SSL 2.0 (Secure Sockets Layer) and uncheck the box of Use TLS 1.0 (Transport Layer Security).increase browsing and download speed windows 8 7 vista

Advanced Workaround – How to Increase Download Speed – Windows Vista only

Update: There are several reports regarding the restoration of TCP autotuning didn’t work after applying the command. Thus, we do not recommend you to try this tweak. This tweak is only for pro and advanced users who know exactly what they are doing. Please proceed at your own risk.

By default, the TCP autotuning is enabled in Windows Vista. Many websites do not respond well with this feature. So these sites are loaded slowly.

  1. To disable TCP autotuning feature, first open the Run option from the Start menu.
  2. Type cmd in the box of Run option.
    run command prompt how to increase download speed
  3. A command prompt will show up, type netsh interface tcp set global autotuninglevel= disabled in it and then hit enter.

  4. The TCP autotuning should be disabled now. Close the command prompt and restart your computer.
  5. To restore or re-enable the TCP autotuning feature,
  6. Type cmd to the Run option and then type netsh interface tcp set global autotuninglevel= normal in the command prompt. Press enter, close it and then restart your computer.
  7. The TCP autotuning should be enabled now.

    While trying to increase the browsing speed following command was given as suggested
    To restore or re-enable the TCP autotuning feature, type cmd to the Run option and then type “netsh interface tcp set global autotuninglevel normal” in the command prompt. Press enter, close it and then restart your computer.
    The TCP autotuning should be enabled now.

    But it wasn’t disabled and a message was appeared. Set global command was failed on IPv4. The requested operation requires elevation.

    You need to go to C:\windows\system32 and right click and open cmd.exe with run as administrator. Then it will work for you.

    Applied both fixes, and still peaking at 110-120Kbps download rate for files and torrents. Upload rate is stuck at about 10-20kbps, which is also totally unacceptable. Base network connection is a 20Mbps, cable connection into a Wireless N, Linksys router. All network cards are at least G+ and N. All systems are running Norton 360 3.0.

    There are the following: iPhone, Windows XP Home, and Windows Vista Home Premium, in use on the network connection in question.

    Speed tests from iPhone generate – ~900KBps
    Speed tests from Win XP generate – ~750D/300U
    Speed tests from Vista H.P generate – 950KB D / 450KB U

    Yeah, that is using the same testing server, and everything. I get those results on my Vista system, but when I go to download a file or host a torrent, KA BLAM! shite download. Does anyone have suggestions. I am a hoping to find an answer as it really bites to only have my tests go fast.

    Thanks Chris for sharing your info with our readers.

    For your info, the tips I suggested here in this post might have a slight improvement and perhaps could fix something for some users.
    As in your case, perhaps there are other problems that we can’t see through. You might have to contact your ISP and tell them your problem.
    Anyway, we appreciate your comment.

    This is perfect. The speed increase much more faster than before but will this affect our computer’s health or internet security? Meaning is it safe to do this?

  • srinija

    In IE, options are already set in the way you told us above but still I have a very bad download speed. I use LAN with 14Mbps in my collage. Could you please help?

  • John Klaide Jocson

    To be honest I’m not good in computers. But when I read your blog. You really are great! I just want to know if the second method is safe? Would it lead to some troubles? Like it might destroy my system?

  • John Klaide Jocson

    What method did you use? Is it the first one with IE thing? Or the second one about using that CMD?

  • John Klaide Jocson

    Have you also solved the things about enabling autotuning?

  • John Klaide Jocson

    Have you already fixed this problem about enabling autotuning?
