Using The Enhanced Write Filter User Interface - HP 2533t - Compaq Mobile Thin Client Administrator's Reference Manual

Using the Enhanced Write Filter user interface

In addition to the DOS command-line tool, the Windows XPe includes an EWF user interface. You can
access the EWF interface through the Windows Control Panel or through the Administrative Tools option
for the administrator.
To access the EWF user interface using Administrative Tools, follow these steps:
1. Log on as an administrator.
2. Select Start > Control Panel > Performance and Maintenance > Administrative Tools.
3. Click the EWF Manager icon.
4. Use the EWF user interface to select Write Filter options.
The EWF user interface includes the following buttons:
● Enable EWF
Enables the Enhanced Write Filter so that data written to the protected media is cached in the
overlays. The current overlay level becomes 1 as soon as EWF is started, and a new overlay is
created at level 1.
●
Disable EWF
Disables the overlay on the specified protected volume.
● Overlay configuration
Displays the overlay information and is a combination of the information supplied when executing
ewfmgr.exe c: -Description and ewfmgr.exe c: -Gauge from the DOS prompt.
● Clear boot command
Clears the boot command from the DOS prompt.
●
Commit data to volume
Commits all current-level data in the overlay to the protected volume, and resets the current overlay
value to 1.
