There are four (4) environmnet variables that can be used in the Recovery Console to expand the functionality:

These variables default to FALSE, but you can set them to TRUE:

set allowwildcards = true - Allows you to use wildcards with some commands (such as "del *.bak").

set allowallpaths = true - Allows you to change directories (the cd command) to include all folders on all drives.

set allowremovablemedia = true - Allows you to copy files from the hard disk to a floppy disk or other supported removable media.

set nocopyprompt = true - Allows you to copy files without being prompted to continue when you are overwriting an existing file.

You must enable the SET command in the recovery Console using any of the following:

         The Security Configuration and Analysis snap-in in Microsoft Management Console (MMC)

         The Domain Controller Security Policy in Administrative Tools.

         The Domain Security Policy in Administrative Tools.

         The Local Security Policy in Administrative Tools.
Use Local Policies / Security Options to enable Recovery Console: Allow floppy copy and access to all drives and all folders.
Then issue a secedit /refreshpolicy machine_policy to initiate a policy refresh. Once the policy is applied, you can use the SET command to set any/all of the four environment variables to TRUE.
