Enhanced Write Filter Manager command line control Ä CAUTION: Terminal Administrators should use Microsoft Windows NT file security to prevent undesired usage of these commands. Ä CAUTION: When using the -commit command, all the temporary contents are permanently written to the flash memory. ✎ Because the Enhanced Write Filter Manager commands are executed on the next boot, you must reboot the system for the command to take effect. Windows XPe includes the Enhanced Write Filter (EWF) console application command line tool, Ewfmgr.exe, which you can use to issue a set of commands to the EWF driver, report the status of each protected volume overlay, and report the format of the overall EWF configurations. By including the EWF Manager console application component in your configuration and building it into your image, you enable use of Ewfmgr.exe and the corresponding commands. To use the Enhanced Write Filter Manager using the command line, select Start > Run > Open and access the system DOS prompt by typing CMD in the Open field and clicking OK. At the system prompt, enter ewfmgr c: and press Enter. Using the ewfmgr -[boot command] syntax, use the following commands in the boot command variable of the command line: -all Displays information about all protected volumes and performs a command, such as disable, enable, and commit, on each volume, if specified. -commit Commits all current level data in the overlay to the protected volume, and resets the current overlay value to 1. You can combine -commit with the -disable command to commit and then disable. Quick Reference Guide www.hp.com 27
