HOW TO UNINSTALL THIS FIX
-------------------------

To remove this package, perform the following steps:

1. Use Windows NT Explorer to go to the folder where IIS is installed (this
   folder is C:\Winnt\System32\Inetsrv by default).

2. Double-click Rmiisupd.cmd and then follow the instructions on your screen.

This command script restores your IIS files to the versions you had before
installing the IIS Update. You may be required to reboot your computer when the
removal is complete.
