Enhanced Write Filter status tool
Windows XPe Image Refresh 5.1.033 includes the EWF status 
service, which creates an icon in the System Tray that shows the 
status of EWF. 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
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: 
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.
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.
