5.1 Enhance Write Filter (EWF)
Enhanced Write Filter is an embedded enabling feature that provides disk write-protection capabilities.
When you enable EWF, the system will be protected. You can delete or add flies, even add a new
hardware. When EWF is enabled anything saved to disk (files, drivers, new hardware) will be
unavailable after restarting the thin client. Any changes to the disk when EWF is enabled are not saved
unless EWF is disabled and changes are “committed”.
The EWF function is used by user:
Administrator
only.
When you logon, you will see the picture that likes pencil. Default color is red. You can left click it by
