Hi - thanks for your reply. Ok, well I think I'm totally confused about what I need to do here then! Here's what I'm doing, and what I'm trying to acheive (I'm working on VMs at the moment, until I get this right!). I need to create a standard desktop for an external customer. They won't be part of our MS volume licensing agreement, and so will be using OEM instead of KMS/MAK keys. All I want is for the end user (actually the install technician) to be asked to provide the computer name and to enter the OEM key during first start up. This should then get to the local admin logon, from where they can do some other tasks as required. I'm installing Win7 & Office 2010 using a configuration set and an autounattend.xml (attached). This gets me into audit mode. In audit mode I install any necessary apps and perform customisations that will be applied to the default user. We need to rename the local administrator account (to fit in with our organisation's support standards) so I do this as per this page. I create a new unattend.xml and save it in a temporary folder C:\unattend (deleted as part of setupcomplete.cmd). I've attached that xml too. I then run sysprep /oobe /generalize /shutdown /unattend:c:\unattend\unattend.xml The machine does its sysprep, restarts, and does indeed ask only for PC name and license key, then gets me to the (renamed) admin logon. Assuming what I've done here is ok, I'll capture this as my install.wim. However - I still think I've done something wrong. Whilst everything seems ok, what's worrying me is the presence of a load of files in c:\windows\panther. I don't know exactly what the files are, but they look as if they're not finished doing something! I've attached a .jpg of the leftover files. I guess what I'm after is either some reassurance that I've nothing to worry about, or a slap in the face and some advice on where I'm going wrong!! I'm sure there's some unecessary duplication in the xml files. Once I get this sorted I can get started on ImageX and creating the recovery image etc! Any advice is very gratefully received. Thanks in advance. AutoUnattend.txt unattend.txt
