Enhanced Write Filter Status Service
This service creates an icon in the System Tray that shows the status of EWF. The EWF Status icon will
appear as a red “lock” when disabled, a green “lock” when enabled, and a yellow “lock” when the
state is set to change on the next boot.
Status Description Example
Red Disabled
Green Enabled
Yellow Commit Mode
Yellow with Red “X” Write Filter Corrupted
Important
In the event of a corrupted EWF state, you will need to re-flash the thin
client unit with the standard shipping image provided on the web.
If you are logged-on as Administrator, you can change the status of EWF by right-clicking on the icon
and selecting the desired EWF state.
Important
Since EWF Manager console utility (ewfmgr.exe) and the EWF status
service execute separate code, any status changes by ewfmgr.exe will not
be automatically reflected by the EWF status icon.
To refresh the status icon after modifying EWF through ewfmgr.exe, you must right-click on the icon
(you can then click anywhere on the screen to close the context menu). However, any operations
made through the EWF status icon menu will be visible through the EWF Manager console
application. Status and changes to the Enhanced Write Filter will be synchronized between the EWF
status icon and the EWF Manager Control Panel applet.
