6.2.3.8 Enhanced Write Filter
Write protection is disabled by default. Use the Enhanced Write Filter menu to enable and
manage it. This allows you to protect the system against modification of any kind. All write
accesses or modifications on an activated EWF drive will be discarded with the next restart.
EWF settings are not saved or loaded to import/export configurations (see “Settings” on
page 72).
The computer's EWF drives are displayed in the EWF Drives field (usually only one). The
settings below apply to the EWF drive selected here.
Note: The Enhanced Write Filter menu is only relevant for the Microsoft Windows XP
Embedded operating system! If EWF is not installed, no changes can be performed.
