4.2.9 Conguring UWF (Unied Write Filter)
Your SC-T47 is UWF-enabled by default. Unied Write Filter (UWF) is a sector-based write lter intercepting all write
attempts to a protected volume and redirecting those write attempts to a RAM cache. With UWF, all system changes
will only aect 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 VCS 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 Notication 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 congure the UWF settings, please do the following:
1. On ViewSonic 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 rst, and then change the memory size used. A restart is required
when you switch the UWF state.
