HP T610 / T510 Thin client SCCM write filters

Hi,

I am deploying T510 and T610 Thin clients using SCCM 2012 Current Branch.

I captured a Cusomized WES7 image ( initially deployed from the HP 8GB image)

Now I am deploying the image and all goes well, only the last part: Finalizing the Task Sequence fails.

It ends up in "Your computer is being serviced" and the Win7 logon screen.

When I reboot, Windows 7 start with"Starting for the first time".

And keeps doing this, because write-filters is now enabled. I can fix this by logging on as Administrator manually and disable the write filters + reboot. It looks like the TS then finishes.

I followed the document provided by HP: http://h10032.www1.hp.com/ctg/Manual/c04920485

And used a Unattend.XML with the settings as described in Appendix-B of this document.

It looks like the Commands from the Unattend.XML work, because Write-filters get enabled.

But Somehow it seems the Tasksequence is not completely finished when the write-filters get enabled.

Pls. any suggestions to get a smooth deployment with write-filters enabled?
