2 Enhanced Write Filter (EWF)

The Enhanced Write Filter (EWF) provides a secure environment for your computer by protecting it from undesired flash memory writes (the operating system and functional software components reside in flash memory). The write filter also extends the life of the computer by preventing excessive flash write activity. Instead of allowing writes directly to the flash memory, it intercepts all flash writes and caches them.

In order to save changes to system configuration settings, you must disable the write filter cache or perform the

-commit

command during the current boot session. Otherwise, the new settings will be lost when the computer is shut down or restarted. If you do not want to make permanent changes, you can enable the write filter.

The write filter cache contents are not lost when you log off and on again (as the same or different user). You can disable the write filter cache after the new logon and still retain the changes.

After you disable the write filter, all future writes during the current boot session are written to the flash with no further caching until the computer is restarted. You can also enable/disable the write filter using the command line.

NOTE: Always enable the write filter after you have made all of your permanent changes.

NOTE: Only an account with administrator privileges can enable, disable, or commit the enhanced write filter.
