FeatureRemoveAll is used during a maintenance install to force the removal of all features that were installed previously. FeatureRemoveAll is generally called when the user selects the Remove option in the SdWelcomeMaint dialog.
Calling FeatureRemoveAll causes all features to be deselected. As a result, when FeatureTransferData is called, any features that have already been installed (determined by reading the setup log file, if it exists) are removed (uninstalled).
Setup determines whether or not features have been previously installed by reading the setup log file. If no valid log file is found during setup initialization, all features are considered not installed. In this case, calling FeatureRemoveAll clears all feature selections, but does not force uninstallation of the features when FeatureTransferData is called.
Note: FeatureRemoveAll also deselects all internal features, including the features containing the Disk 1 setup files that are automatically installed to the DISK1TARGET location.
