instructions on the screen.
The Windows 7 Ultimate operating systems do not support EWF!
8.5 Windows 7 ® Embedded MUI
8.5.1 EWF (Enhanced Write Filter)
What is EWF?
The Enhanced Write Filter is a write protection and it protects the POLARIS Panel PCs
operating system if there is a power failure, ensuring that the POLARIS Panel PCs will be
able to start perfectly.
What is the as-delivered condition?
The Windows 7 ® Embedded MUI are supplied with an activated EWF (Enhanced Write
Filter).
The data carrier that is used is divided into:
Partition C
boot drive with operating system protected by EWF
Partition D
application data (e.g. BMS Graf Runtime) not protected by EWF
Behaviour when EWF is activated?
Partition C
When the EWF is activated, it is not possible to write on Partition C. All write accesses to
the C: partition are redirected into an RAM overlay. The changes that are made are
not
available after rebooting.
Partition D
Is not protected by EWF. Write access to Partition D is possible at any time. The data is
still available after a reboot.
Data can be lost during write access if there is a power failure.
