How do I repair Internet Explorer in Windows® XP?
Revised - 03/03/2002
The ability to Repair Internet Explorer does not exist in the version that
ships with Windows XP. This feature only becomes available after you
upgrade to a newer version. This is normal and has been this way since
Windows 98 and IE4.
However, you can reinstall IE in Windows XP by clicking Start, Run and
entering the following command:
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132
%windir%\Inf\ie.inf
You will need to have your XP CD available.
Some people have problems with the command line above. A small VB Script
that will execute the command for you can be downloaded here. Save the file
to your hard drive and double click it to run IE Setup.
