Filter

This chapter describes how to use the Enhanced Write Filter secu-

rity features to protect your Neoware XPe thin client.

Microsoft's Enhanced Write Filter is a file system utility that can be

set to take all disk write activity that would normally go to the C:

drive (a Flash disk in Neoware thin clients) and redirect them to a

RAM cache, instead. Disk reads come from the Flash disk and

RAM cache.

When an Enhanced Write Filter protected thin client restarts, the

original contents of the disk reappear, unchanged. With Enhanced

Write Filter engaged, the integrity of the original disk's contents is

protected. Enhanced Write Filter is ideal for point-of-sale, kiosk, or

any application that could be adversely effected by inadvertently

installed software (such as Internet Explorer plug-ins or cookies),

as well as making a protected thin client less susceptible to virus

infection.

Note that the Registry Filter enables Microsoft Licensing and

Domain Machine password synchronization to be saved even when

Enhanced Write Filter is enabled.
