After you run Microsoft Windows 98 Setup, you are unable to uninstall Internet Explorer version 5.
This issue can occur if you run Windows 98 Setup on a computer that is already running Internet Explorer version 5. Windows 98 Setup removes the ability to uninstall Internet Explorer version 5 to protect important system files.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

When you install Internet Explorer version 5 on a Microsoft Windows 98/95-based computer, it installs a migration dynamic link library (.dll) file, and backs up any operating system files it replaces.

One of the functions of the migration file is to protect the files needed by Internet Explorer version 5 if you reinstall your operating system.
