Hi, all

Yesterday I saw a machine which uses XPE as OS and EWF partition is enabled.
What supprised me is that there is a program called Writer Filter, which is
used to write data to the EWF partition. We know that EWF partition is read
only. So how could this program manage to do this? I searched help but found
nothing about it. So I guess it's a third-party tool on XPE. I think it's
very useful. For example, if I want to add a printer driver, a usb driver,
etc., I don't have to rebuild the image again. Simply by run this program
after installing drivers on the released image, everything will be settled.
Does anybody know how to get such a tool?

DUA is not what I want. All that I want to do is to install drivers on an
EWF enabled image, just like on an EWF disabled one.

I have an EWF enabled image which running on many machines at many places.
At different places, people use different printers. I don't want to build
different images due to different printer drivers. So, how to install the
printer driver locally on an EWF enabled machine? You say there is EWF API
or ewfmgr.exe that can do this, where can I find some examples?

Thx

Hi Maverick,

Please tell us what you want to do.

EWF partition is not read-only. You can access if from disk level.
Also EWF buffer all data in memory or disk, and with EWF API or ewfmgr.exe
Click to expand...
you can commit data to protected partition.

In product documentation of course.

ewfmgr c: -commit
After that reboot your device.

Or if your printers and other devices are PnP (most of them are). You can make components so they will copy all required files and
settings and let PnP use install and use appropriate drivers each time it boots.

So your user can plug any hardware and after reboot if that hardware is not present it will not be installed any more and registry
will stay clean.
