Administrator Guide
– Warning #2 (%)—Shows the UWF cache percentage value at which a Critical Memory warning message is displayed to the user.
Once the memory level crosses the warning level 2, system automatically restarts. (Default value = 90, Minimum value = 55,
Maximum value = 90)
• Enable UWF—Allows you to enable the Unied Write Filter and prompts you to restart the Wyse Software thin client device. To save
the changes, restart the Wyse Software thin client. After the system restarts to enable the Unied Write Filter, the Unied Write Filter
status icon in the desktop notication area turns green.
• Disable UWF—Allows you to disable the Unied Write Filter and prompts you to restart the Wyse Software thin client device. To save
the changes, restart the Wyse Software thin client. After disabling the Unied Write Filter, the Unied Write Filter status icon in the
desktop notication area turns red and the Unied Write Filter remains disabled after the system restarts.
• Defaults—Allows you to reset the UWF Cache Settings area, and the UWF Warning Settings area to their default values.
• File Commit area
– File Path—Allows you to add, remove, and commit les to the underlying media. The system does not restart the Wyse Software
thin client device. The changes are committed immediately.
NOTE: Delete a le path from the list, if the le is not
committed.
• Current Session Exclusion List
– File/Directory Path—
Allows you to add and remove a le or directory, to or from the exclusion list for the next session. This retrieves the list of les or
directories that are written through in the current session and the title of the pane is shown as Current Session Exclusion List. The
Next Session retrieves the list of les or directories that are written through for the next session and the title of the pane is shown
as Next Session Exclusion List. The system will not restart the Wyse Software thin client, and the changes are not committed until
an administrator restarts the Wyse Software thin client device manually.
UWF Overlay is changed from RAM to disk to congure the overlay size appropriately. UWF overlay is congured to disk overlay to have
improved up time for software dened thin clients.
Enable page le— MS UWF does not support page le conguration on write protected disk on which the overlay is congured. To
accommodate the page le, an additional unprotected volume is created where the page le is congured.
NOTE
: Unied Write Filter and Dell Write Filter are not supported on Windows 10 Pro.
Dell Write Filter
Dell Write Filter (DWF/FBWF) is a le-based write lter that protects your storage media on a Windows 7 desktop operating system. DWF
intercepts all write attempts to a protected volume and redirects those write attempts to an overlay. The overlay is stored in a folder on the
same volume. The size of the overlay is limited to the amount of free space available on the volume. Exclusion lists are supported for les
and folders.
DWF improves the reliability and stability of your device and improves system security since unauthorized changes to the system are
discarded. In DWF, an overlay is a virtual storage space that saves changes that are made to the underlying protected volumes. Any time
the le system attempts to modify a protected le in the overlay, DWF instead copies the le from the protected volume to the overlay and
modies the copied le in the overlay. If an application attempts to read the le, DWF returns the data from the overlay. The le in the
protected volume remains unchanged.
