About UWF (Unied Write Filter)
Before getting started on client conguration through the ViewSonic Client Setup console or through the Windows
Embedded Standard operating system, please note that in a session any changes to the system will not be kept
by default after the system restart. This is due to a special feature called UWF (Unied Write Filter) in your Windows
Embedded-based system.
By default, your SC-T47 is UWF-enabled. 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 virtual overlay. With UWF, all system
changes will only aect the session where the changes are made. After restart, all changes will be discarded.
You can change the default via the ViewSonic Client Setup console. It’s strongly recommended that you read the
related section in this user’s manual rst before making any changes to your system.
WARNING
• Please read the following section FIRST before making any changes to your system:
“4.2.8 Conguring UWF (Unied Write Filter)” on page 52.
NOTE
• As a thin client device, your SC-T47 is mainly for access to remote or virtual desktops
on servers. With the limited and protected (UWF-enabled) hard disk space, it’s not
recommended to save data on your SC-T47. Instead, you can use storage spaces
over remote / virtual desktops, removable storage devices, or networks.
• In case that you need to copy a le to the protected volume, ensure that its size is
smaller than the free memory (overlay) space. Otherwise, your system may have
unexpected results or become unresponsive.
