Introduction:
Internet Explorer 7 (IE7) is light years ahead of its predecessors, but by no means does that proclamation mean that the browser is perfect. You are still going to encounter issues with IE from time to time.
Here are some of the concise guides that deliver some troubleshooting steps that will clear up the majority of issues we encountered with IE7.
Issues with Internet Explorer 7.0 with solutions
Problem: Crashes or hangs
If IE crashes, the most likely problem is that there's a buggy add-on (Toolbar or Browser Helper Object). In order to verify and isolate the buggy add-on, follow these steps:
1. Start IE in No Add-ons mode, either by right-clicking the Desktop icon, or clicking START - RUN and typing: iexplore.exe -extoff
2. Determine if IE fails.
3. If not, use Tools - Manage Add-ons to disable all browser extensions and toolbars.
4. Restart IE and re-enable browser extensions one-by-one.
5. Once you've found a broken extension, contact the manufacturer and ask for an update.
(Reference: http://support.microsoft.com/?id=928426)
If IE still crashes often, even when browser add-ons are disabled:
• Please ensure that you are running the very latest version of your anti-virus, anti-malware, and/or firewall programs.
• Please ensure that the drivers for your graphics card are up to date.
• If you have Google Desktop installed, please ensure that you update to the latest version of Google Desktop.
• If you have 7-Zip or other Windows Explorer extensions installed, please ensure that you update to the latest.
Problem: Cannot connect to Internet using IE after updates installed
If you see the "Page Cannot be Displayed" error after installing Internet Explorer updates from Windows Updates, it's possible that you have a 3rd party firewall installed that is blocking access because the IE files have been updated. Please see http://support.microsoft.com/kb/942818/en-us for more information.
Problem: IE always starts in "No Add-ons" mode
The problem is that you're launching Internet Explorer using a shortcut icon that has the "-extoff" command line parameter. That parameter causes IE to start without add-ons. Thus, every time you use that shortcut icon, IE will start in No Add-ons Mode.
1. How do you normally start Internet Explorer? Right-click whatever icon you're using to start IE, choose "Properties" and remove the -extoff part of the shortcut.
2. If you click the green START button, click Run, type iexplore.exe in the RUN box, then hit the ENTER key, IE will start with Addons enabled.
Problem: IE opens small windows
IE opens new windows at the size of the last closed window. If you find that IE is opening small windows, do this:
• Close all IE windows.
• Open one new IE window.
• Adjust that window to the size you prefer. Do this by dragging the window borders. Do not use the maximize button:
• Close the IE window.
• New IE windows will open at the size you chose.
Problem: ClearType Text appears fuzzy
IE7 turns on a text-smoothing technology called "ClearType" by default. ClearType is scientifically proven to make text easier to read, particularly on LCD flat panel monitors.
If ClearType looks fuzzy on your monitor, you might want to try the ClearType tuning wizard, which can help you adjust the display of ClearType.
If you still don't like the appearance of ClearType, you can turn it off by unchecking the checkbox: Tools - Internet Options - Advanced - Multimedia - Always use ClearType for HTML.
Problem: IE Startup takes a long time (>3 seconds)
1. IE may start very slowly if you have a huge number of sites listed in your Restricted or Trusted sites zone. Some tools, like "SpyBot Search & Destroy" will place thousands of sites in these zones if you use their "immunize" feature.
2. Follow the "Crashing on startup" steps above to see if starting in No Add-ons mode starts much faster
3. If you're not using a proxy, uncheck IE's "Automatically detect settings" option on the Tools - Internet Options - Connections - LAN Settings dialog.
Problem: Slow Page rendering
1. Increase the connection limit. This tweak allows IE to make up to 16 connections per server.
2. Ensure that both "HTTP1.1" checkboxes in Tools - Internet Options - Advanced are checked.
Problem: IE7 Setup fails to install Internet Explorer
See http://support.microsoft.com/kb/917925
Problem: My address bar won't turn green?
IE7 includes a cool new feature that turns the address bar green when a secure site presents an Extended Validation certificate:
If you're having trouble with this feature, on a site you know has an EV certificate:
1. Ensure that you either have the Phishing Filter set to "Automatic" mode or Tools > Internet Options > Advanced > Security > Check for Server Certificate revocation checked.
2. If that doesn't work, install this: Windows Root Certificate Update and restart.
Problem: After installing, IE7 starts then vanishes
It's possible that one of IE's DLLs isn't installed correctly
1. Click START - RUN and type cmd
2. In the command prompt, type cd\
3. In the command prompt, type cd Program Files
4. In the command prompt, type cd Internet Explorer
5. In the command prompt, type regsvr32 IEPROXY.DLL
(Reference: http://support.microsoft.com/?id=928427)
Problem: Error message about PSAPI.DLL
If you install IE7 and the following error message begins to show:
The procedure entry point GetProcessImageFileNameW could not be located in the dynamic link library PSAPI.DLL
1. Search your hard disk for PSAPI.dll.
2. Any copies of this DLL that are found outside of the Windows or Windows\System32 folder should be renamed to PSAPI.bak.
Problem: IE always goes to http://runonce.msn.com/runonce2.aspx instead of my homepage
If IE7 always goes to the RunOnce page on startup, even after you've tried to save the first run settings, it's possible that the mechanism that IE is using to save the settings does not work for some reason.
You can prevent IE from going to the RunOnce page and cause it to go directly to your homepage by running this script.
For more info, check out this Knowledge Base article.]
Problem: IE always goes to http://www.microsoft.com/windows/downloads/ie/getitnow.mspx instead of my homepage
If Internet Explorer always goes to this page on startup, it's likely that you have an anti-spyware package (like "SpyBot") that prevented IE from correctly modifying your registry.
Try running this script. Note: you may need to disable your anti-spyware tool temporarily for the script to work.
Problem: On startup, IE always shows an error message about the AOL toolbar
If you see the following error message every time IE starts:
"Cannot find 'file:///C:/Program%20Files/AOL%20Toolbar/welcome.html'. Make sure the path or Internet address is correct."
..then you've hit a bug in the AOL Toolbar.
Try running this script. Note: you may need to disable your anti-spyware tool temporarily for the script to work.
Problem: I installed a "branded" version of IE7, but I'd prefer a "plain" copy without toolbars and customizations.
An article on this topic can be found here: How to remove branding in Internet Explorer 7.
Problem: Malware / Adware
If Internet Explorer is behaving strangely (crashing, visiting unwanted sites, etc), it's possible that there is malicious software installed on your computer.
As a first step, you should allow your antivirus software to scan and attempt to repair your computer. Additionally, you may want to try the following Microsoft tools:
• Windows Defender
• Windows Live OneCare
• Windows Live Safety Center
• Malicious Software Removal Tool
You should also ensure your computer has all the security updates available at Microsoft Update.
Problem: My searches are redirected to unrelated sites and I cannot connect to WindowsUpdate or antivirus websites
If Internet Explorer searches are redirected to unrelated sites or search engines, it's possible that your computer was infected with malware (see the previous tip). However, if your computer is not currently infected with malware, it's possible that at some time in the past, malicious software altered your computer's DNS settings. DNS works like an "internet phonebook" that maps URLs (like "windowsupdate.microsoft.com") to internet protocol addresses (like "207.46.225.221").
To determine if a malicious DNS server is configured:
- Go to Start -> Control Panel ->Network Connections.
- Right click your default connection, usually Local Area Connection or Dial-up Connection, if you are using Dial-up, and left click on Properties.
- Double-click on the Internet Protocol (TCP/IP) item
Check to see if you're set to something other than "Obtain DNS servers automatically". If so, contact your ISP to ensure that the address specified is correct, or set the "Obtain DNS servers automatically" checkbox. Then restart your computer.
Problem: After opening many tabs, Windows and IE paint abnormally.

Problem: A remote user is having networking problems with Internet Explorer. How can I collect information about his system to help me to troubleshoot?
Have the user run Netcheck and send you the log file.
Problem: Overlong headers result in HTTP/4xx or HTTP/5xx errors, particularly on devices like routers or webcams
Problems of this nature are usually caused by one of the two request headers in yellow being longer than the device expects.
GET / HTTP/1.1
Accept: image/gif, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, application/x-silverlight, application/x-silverlight-2-b2, */*
Accept-Language: en-us
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; WOW64; Trident/4.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; InfoPath.2; .NET CLR 3.5.30729; .NET CLR 3.0.30618; OfficeLiveConnector.1.3; OfficeLivePatch.1.3; MS-RTC LM 8)
Accept-Encoding: gzip, deflate
Connection: Keep-Alive
Host: 192.168.10.1
These headers are dynamically generated out of registry keys. They can usually be trimmed by editing the registry without any important side-effects.
To trim the list in the Accept header, click START > RUN > REGEDIT.EXE. Using RegEdit, navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents
..and remove elements from the "Name/Type/Value" list to remove values that aren't strictly required. Elements in red are of lower importance than those in black:
image/gif, image/jpeg, image/pjpeg, application/x-ms-application, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, application/x-silverlight, application/x-silverlight-2-b2, */*
A similar problem can occur with the User-Agent header.
To trim the list in the User-Agent header, click START > RUN > REGEDIT.EXE. Using RegEdit, navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent\Post Platform
..and remove elements from the "Name/Type/Value" list to remove values that aren't strictly required. Elements in red are of lower importance than those in black:
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; WOW64; Trident/4.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322; InfoPath.2; .NET CLR 3.0.30618; .NET CLR 3.5.30729; OfficeLiveConnector.1.3; OfficeLivePatch.1.3; MS-RTC LM 8)
