Using the Enhanced Write Filter

The Enhanced Write Filter (EWF) provides a secure environment for your computer by protecting it from undesired flash memory writes. In order to save changes to your system configuration settings, you must commit your changes in the EWF. Otherwise, the new settings will be lost when the computer is shut down or restarted.

For additional information on the EWF, see your network administrator.
