4.2.10 Configuring UWF (Unified Write Filter)
Your t68WD is UWF-enabled by default. Unified Write Filter (UWF) is a sector-based write filter intercepting all write
attempts to a protected volume and redirecting those write attempts to a RAM cache. With UWF, all system changes
will only affect the session where the changes are made. After restart, all changes will be discarded.
WARNING
• The UWF feature is enabled by factory default.
Except for changes to ACS settings
,
all the changes made in a session will not be kept after the system restart. Ensure
that you choose the desired settings here before making any changes to the system.
• An icon in the Notification area of the Taskbar will indicate the current UWF state
of your system. For details, please refer to the description at the end of this section.
To configure the UWF settings, please do the following:
1. On Atrust Client Setup, click
System
>
UWF
.
2. Click the State drop-down menu to enable/disable the UWF feature.
3. Click to select other options if needed.
TIP
• You can change the maximum memory size used
only when UWF is disabled
.
Disable UWF first, and then change the memory size used. A restart is required
when you switch the UWF state.
