system session. Otherwise, the new settings will be lost when the thin client is shut down or restarted.
The File Based Write Filter cache contents are not lost when you simply log off and on again as the
same or different user; that is, you can flush the files of the File Based Write Filter cache after the new
logon and still retain the changes. For instructions on flushing, see Before Configuring Your Thin
Clients. For detailed information about the File Based Write Filter, see Using the File Based Write Filter
NOTE: A user cannot flush the files of the File Based Write Filter cache; this is a local or remote
•NetXClean Utility — NetXClean is a clean-up utility that keeps extraneous information from being
stored on the flash memory. Clean-up is triggered automatically on restart, shut-down, or user log-
off. If you want to keep certain profile configurations for example, printers, be sure to configure
NetXClean to refrain from cleaning up any number of explicitly declared profiles. For details about
NetXClean, seeBefore Configuring Your Thin Clients and Understanding the NetXClean Utility.
•Power Management — A Monitor Saver turns off the video signal to the monitor, allowing the monitor
to enter a power-saving mode after a designated idle time. Power settings are available in Start →
Control Panel → Power Options.
•Wake-on-LAN — This standard Windows Embedded Standard feature discovers all thin clients in your
LAN, and enables you to wake them up by clicking a button. This feature allows WDM software, for
example, to perform image updates and remote administration functions on devices that have been
shut down or are on standby. To use this feature, the thin client power must remain on.
•NOTE: Wake on LAN feature will not work by default for laptop clients; you must enable the
feature in the bios. In addition, for a laptop client, only S3 mode is supported the S5 mode is not
•Thin Client Time —After power off, clock time will not be lost as long as the power source remains
on. Clock time will be lost if the power source is off and a battery is not installed. The local time utility
can be set to synchronize the thin client clock to a time server automatically at a designated time, or
Correct time should be maintained as some applications require access to local thin client time.
Use the Date and Time dialog box Start → Control Panel → Date and Time or by clicking the
time area in the taskbar and then clicking the Change date and time settings link to edit the time
and date as needed.
Using the File Based Write Filter (FBWF)
The File Based Write Filter provides a secure environment for thin client computing by protecting the thin
client from undesired flash memory writes flash memory is where the operating system and functional
software components reside. By preventing excessive flash write activity, the File Based Write Filter also
extends the life of the thin client. It gives the appearance of read-write access to the flash by employing a
cache to intercept all flash writes and returning success to the process that requested the I/O.
The intercepted flash writes stored in cache are available as long as the thin client remains active but are
lost when the thin client is restarted or switched off. To preserve selected changes, the selected files of
the cache can be transferred to the flash on demand by using WDM software or manuallyby using
Commit in the File Based Write Filter Control dialog box; alternatively, if the files affected by the changes
are not known, the changes can be made after disabling the File Based Write Filter using the File Based
