4.5 KEB UWf Manager
4.5.1 Introduction
The KEB UWF Manager offers a simple interface to use Microsoft's Unified Write Filter
in Windows 10.
4.5.2 functioning of the UWf
UWF protects your volume from write access by redirecting all write commands to a
virtual overflow. The virtual overflow is a temporary memory, which is either in RAM or
directly on the volume and which is cleared when the device is restarted. Any change
made to the overflow affects the image, but if the change is undone, the image remains
unchanged.
If the UWF is enabled for a volume, no data are permanently stored on this volume. In
case of a restart or power failure, the overflow will be reset and all data from the previ
-
ous session will be lost. The view will be the same after each reboot and is therefore
protected against damage that can be caused by a power failure.
4.5.3
KEB UWF Configuration and usage
To protect the system on volume C:\ including the registry, the overflow is configured
with 4096 MB on the hard disk as standard.
KEB recommends the use of a write filter in order to increase the longevity of the devices
and the data integrity. UWF Manager is disabled at the time of delivery, in order that the
user can make changes during the start-up process.
Each time the device boots up with disabled UWF, the user is reminded to activate the
write filter. As soon as the start-up is completed, the user can activate the write filter
directly by clicking "Yes".
To activate the UWF Manager or to display more information about the current protec-
tion status, the KEB UWF Manager should be used, because it provides a more intuitive
configuration option compared to the command line tool provided by Microsoft.
