HOW TO UNINSTALL THIS FIX

To remove this package, perform the following steps:

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