I have a batch of Latitude 3460's with WES7 64 bit installed.  As part of the deployment to end users these are customized by means of local group policy lock downs, wallpaper changes, region and language changes, the VMWare apps removed, Teamviewer and a printer driver installed.  As you can imagine doing this manually one by one is time consuming so I have used MDT 2013 to sysprep and capture a configured 3460 (the FBWF is disabled at this point) and then created a standard client install task sequence in MDT to deploy the captured image.

Everything works fine until I come to enable the FBWF after deployment.  I am running a batch file with the following contents (the exclusions taken from a configured 3460 before sysprep):

When I reboot I get the following message:

[IMG]s15.postimg.org/.../IMG]

If I then open explorer in the background, disable the filter, reboot, run the above batch file again and reboot the filter works at expected from that point on.  There is no pattern to this either as on a couple of occasions I have had to disable and run the batch file 3 or 4 times to get it to kick in and on another I've been able to run the batch file while the message above was displayed, reboot and it kicks in.  I feel like I'm missing a step but can't figure out what and looking for help.  I have tried to speak to Dell on this but I'm struggling with their support as I am being transferred between different departments several times and nobody seems to understand what Windows Embedded or a write filter is.

Any ides?
