Recovery console: Allow floppy copy and access to all drives and folders
Applies to
- Windows 11
- Windows 10
Describes the best practices, location, values, policy management and security considerations for the Recovery console: Allow floppy copy and access to all drives and folders security policy setting.
Reference
This policy setting enables or disables the Recovery Console SET command, which allows you to set the following Recovery Console environment variables.
- AllowWildCards. Enables wildcard support for some commands, such as the DEL command.
- AllowAllPaths. Allows access to all files and folders on the device.
- AllowRemovableMedia. Allows files to be copied to removable media, such as a floppy disk.
- NoCopyPrompt. Suppresses the prompt that typically displays before an existing file is overwritten.
You might forget to remove removable media, such as CD or floppy disk, with sensitive data or applications that a malicious user could then steal. Or you could accidentally leave a startup disk in the computer after using the Recovery Console. If the device is restarted for any reason and the BIOS has been configured to boot from the removable media before the hard disk drive, the server will start from the removable disk. This boot causes the server's network services to be unavailable.
Possible values
- Enabled
- Disabled
- Not defined
Best practices
- Set Recovery Console: Allow floppy copy and access to drives and folders to Disabled. Users who have started a server by using the Recovery Console and logged in with the built-in Administrator account won't be able to copy files and folders to a floppy disk.

Policy management
This section describes features and tools that are available to help you manage this policy.
Restart requirement
None. Changes to this policy become effective without a device restart when they're saved locally or distributed through Group Policy.
Group Policy
Setting and deploying this policy using Group Policy takes precedence over the setting on the local device.
Policy conflicts
None.
Command-line tools
Enabling this security option makes the Recovery Console SET command available, which allows you to set the following Recovery Console environment variables:
- AllowWildCards: Enable wildcard support for some commands (such as the DEL command).
- AllowAllPaths: Allow access to all files and folders on the device.
- AllowRemovableMedia: Allow files to be copied to removable media, such as a floppy disk.
- NoCopyPrompt: Don't prompt when overwriting an existing file.
Security considerations
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
Vulnerability
An attacker who can cause the system to restart into the Recovery Console could steal sensitive data and leave no audit or access trail.
Countermeasure
Disable the Recovery console: Allow floppy copy and access to drives and folders setting.
Potential impact
Users who have started a server through the Recovery Console and logged in with the built-in Administrator account can't copy files and folders to a floppy disk.
