IE8 64-bit Windows 7 and the Mobile Code Bug (Part 2)

William Stanek here, continuing to talk about a scripting/programming bug that was driving me absolutely bonkers. The code bug is this:

Often when you visit web sites and are using Internet Explorer 8 on 64-bit Windows 7, you are redirected to a web page optimized for mobile browsers - and mobile browser pages aren't exactly what I call user-friendly. Most mobile browser pages provide only summary information, which is nothing like what you actually are searching for.

Here were my original examples:

  • Visit and get redirected to
  • Visit and get redirected to
  • Visit and get redirected to

I told readers: Good luck finding anything on these mobile sites... except for frustration. And added:

To be clear, the problem isn't with Internet Explorer 8 or Windows 7. The problem is with the programming/scripting code on the many sites having this problem. The JavaScript/Java Server Pages/Whatever code is interpreting the browser information incorrectly and as a result, the user is redirected to a mobile browser page instead of the normal page.

The original post is here. How many webmasters responded so far and took corrective action? Out of 25 sites I bookmarked: 3. Out of the 3 listed above: 1 ( is working).

Thanks for reading, time for me to get back to work! Hope you'll take a look at my new book Windows 7: The Definitive Guide. Also just released is my book Exchange Server 2010 Administrator's Pocket Consultant.

I thought I'd take a look at this just out of curiosity and I think they're all repaired now. Both and worked as expected. I'm running 64-bit Windows 7 Pro and tested with both IE browsers.

Good to see. Intel, Sony, Etrade are all fixed. Hopefully all the others too. That was quick--I guess word can travel fast! I was rather tired of experiencing that problem for the past months, and I'm sure many others were too (but may not have realized the source of the problem).

I'm on 32 bit Windows 7 and IE 8. For me, eTrade and Sony appear to be still be redirecting to the mobile sites. Intel seems to be working, although, I never tried it previously, so it may have always been working for me.

fwiw, i used Fiddler to see the USER-AGENT string that the browser is sending and it is :
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; OfficeLiveConnector.1.4; OfficeLivePatch.1.3; Creative AutoUpdate v1.40.01)

Hi Dave,

Thanks for your comments! The info in my blog posts spread far and wide, and I'm seeing this problem is pretty much eliminated. Hopefully, you will find this to be true across the net soon as well.



I have an advent 5302 and just installed windows 7. The sound crackles and neither microsoft or realtek have the solution.
To be honest I dont think they care.

I am still having the redirect to occur for It doesn't happen with my older computer using ie 8 but only my newer laptop.

Hi Mark,

One possible reason is that your browser is still caching the old page. If so, you can clear this up by cleaning out the browser cache and/or forcing the browser to reload the page. Hope this helps.


Hello William,

I think you are on the right track in this and other related blog posts you have made with this being an issue with the code that webmasters are using to interpret the USER-AGENT string, but your suggestions haven't worked for me. I did find a great post that applied to my situation, so I thought it would be good to mention it here to help others like me looking for a solution to this INCREDIBLY ANNOYING issue. Like you, this has been driving me absolutely bonkers for a long time (since I got my current desktop); the problem initially occurred on Vista x64, and continues on Windows 7 Ultimate. So for me, the problem isn't Windows 7-specific as you imply in your post heading. On the Microsoft Answers site (, user Genopsyde identified the issue as the registry key "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform" containing a certain value. I had the same value in my registry, and removing it resolved the issue. I did a little more experimenting and found that this is not specific to Creative sound cards; it's actually caused by the word "AutoUpdate". So if ANY company installs software that adds a string value to that registry key with the word "AutoUpdate" in the value name, the problem occurs. To resolve the problem, remove the string value from the registry.

This solution fixed the problem for me - which has existed on two computers for months! The source appears to have been a Creative AutoUpdate.

Thanks heaps Mark


I do NOT see this problem resolved at all. There appears to be something else at work here.

I think there is something in IE8 or W7 or some installed program that is an issue. I have two PCs. One works fine, the other goes to mobile - and and still go to mobile on the affected machine even after flushing the cache.. works fine.

I am facing the same problem too with and IE8 on Win 7 64 bit. It just redirects to the mobile version. I flushed cache, deleted history. Would appreciate help if anyone knows how to resolve the issue.

The solution posted by "Mark Faletra" pertaining to removing the registry key FINALLY fixed the problem for me after months of having to use Firefox to get to ETrade. Make you close out all IE windows after deleting the registry key. It should then work once you open a new window.

I'm having this problem with all newspaper sites as well as some banking sites. I have searched throughout my registry key and do not have any "creative autoupdate" entries at all. Does anyone know how to fix this problem when it is not the registry key? Please see my key below:

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; NET_lghpset; GTB6.6; SLCC1; Media Center PC 5.0; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C)

I resolved the problem by removing the NET_lghpset from the user agent string. The web site will redirect to mobile if you have NET_lghpset in your UA string.

One thing I haven't been able to determine is "what software added NET_lghpset to my UA string?" Anyone know ?
