How do I… Uninstall Microsoft Internet Explorer 7?

The venerable Web browser continues to evolve. No longer just an application for displaying HTML, the Web browser now has to handle JavaScript, PHP, Java, Active X controls, loosely coupled Web services, plug-ins, multimedia, XML, RSS feeds and more. The Web browser has become an integral part of the total computer experience. All of those expectations make choosing a preferred browser more important than many ever thought it would or should be.

Microsoft Internet Explorer 7 (IE7) and Mozilla Firefox 2 are the latest Web browser contenders for your attention (apologies to fans of Opera and other Web browsers, but these are the two that garner the most attention). Many of us have tried both and made a decision about which is the browser of choice.
If you have chosen Firefox 2, then you may want to uninstall IE7. But this brings up two questions: Can you uninstall IE7 and if you can how do you do it? The answers are: Yes, you can and here’s how.
Uninstall IE7If your installation of IE7 was successful and uneventful, then uninstalling it is relatively simple process. The following steps will uninstall IE7 and restore IE 6.

Click Start, and then click Control Panel.
Click Add or Remove Programs.
Scroll down to Windows Internet Explorer 7, click it, and then click Change/Remove.
If for some reason Windows Internet Explorer 7 does not appear in the Add or Remove Programs, you should:

In some cases, you may get an error message when you try to uninstall IE7 that says you cannot uninstall from a specified user account. To get around this check you will have to edit the Windows Registry.

Warning: Editing the Windows Registry incorrectly can cause the Windows operating system to stop functioning completely. This is an advanced operation and you are encouraged to back up the Windows Registry before you attempt any editing of the file. You have been warned.

Click Start, click Run, type regedit, and then press ENTER.
Navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer.
Right-click the Internet Explorer key, click New, and then click DWORD value.
Type InstalledByUser as the name, and then press ENTER to finish creating the new registry value.
Try to uninstall Internet Explorer 7 again.
