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:

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

Commit data to volume

Commits all current-level data in the overlay to the protected volume, and resets the current overlay value to 1.
