HP Unified Write Filter
HP Unified Write Filter (UWF) is a new feature for WES 8, and is not available as part of Windows 8.
UWF integrates the functionality previously available in Enhanced Write Filter (EWF), File-Based
Write Filter (FBWF), and Registry Filter in WES 7.
UWF is a sector-based write filter that you can use to protect your storage media. UWF intercepts all
write attempts to a protected volume and redirects those write attempts to a virtual overlay. This
improves the reliability and stability of your device and reduces the wear on write-sensitive media,
such as flash memory media like solid-state drives. You can also use UWF to use read-only media to
start and run WES 8.
With UWF, you can specify that certain files, directories, or registry keys are excluded from being
filtered. Excluded files and directories are tracked in a file exclusion list, and excluded registry entries
are tracked in a registry exclusion list. Writes to items in an exclusion list are written directly to the
protected volume.
HP UWF command-line tool
WES 8 includes the UWF command-line tool, uwfmgr.exe. It helps to configure and retrieve settings
for UWF.
The use of uwfmgr.exe and the corresponding commands are enabled by default. To access the
UWF command-line tool:
▲
Type command in the modern UI and type uwfmgr.exe in the Command Prompt.
HP UWF GUI tools
In addition to the command-line tool, HP WES 8 image includes two HP UWF GUI tools providing a
subset of UWF command-line tool functions to help customer do UWF common settings in a
convenient way.
