Enhanced Write Filter status tool

The HP XPe Images include an EWF status service, which creates an icon in the System Tray that shows the status of the EWF. In addition, you can right-click on the icon to display and execute the available options.

The EWF Status icon appears as a:

red lock when disabled

green lock when enabled

yellow lock when the state is set to change on next boot

NOTE: In the event of a corrupted EWF state, you must re-flash the thin client with the standard shipping image provided on the Web. For additional information, see the HP Compaq Thin Client Imaging Tool white paper located at http://h20000.www2.hp.com/bc/docs/support/SupportManual/ c00485307/c00485307.pdf.

If you are logged on as Administrator, you can change the status of EWF by right-clicking the icon and selecting the desired EWF state.

NOTE: Since EWF Manager console utility (ewfmgr.exe) and the EWF status service execute separate code, status changes by ewfmgr.exe are not automatically reflected by the EWF status icon.

If you modify the EWF using the command line, you must right-click the icon (you can then click anywhere on the screen to close the context menu) to refresh the status icon display. The status icon display is refreshed automatically when you make modifications through the EWF Control Panel applet. The EWF applet always reflects the current status.
