CAUTION: Please follow proper write filter and Windows Page File usage instructions at all times. Such
instructions include making sure that the write filter is enabled during regular use and is disabled only
temporarily by an administrator when required for image upgrades, applying security patches, registry changes
and application installation. The write filter should be re-enabled as soon as such tasks are completed. Such
instructions further include never enabling the Windows Page File feature during regular use of the thin client.
Any operation of a Dell Wyse Windows Embedded Thin Client with the write filter turned off during regular
use and/or with the Windows Page file enabled will prematurely wear out your Flash/SSD storage, decrease
performance and decrease the lifespan of the product. Dell is not responsible for, and will not, warrant, support,
repair or replace any thin client device or component that fails to operate properly due to a failure to follow
these instructions.
