Windows_could_not_parse_or_process

I just discovered an issue with using MDT to integrate Internet Explorer 10 into Windows 7 image files. Building the images was no problem, but when I tried to deploy them it would bomb with this error every time:

“Windows could not parse or process the unattend answer file for pass [specialize].

Obviously the issue was with the unattend.xml file that gets auto-generated by MDT, but all the items under “specialize” had worked just fine when I built the image and the IE version was the only item that had changed. After comparing the Windows 7 & Server 2008 R2 unattend.xml files to my Windows 8 & Server 2012 unattend.xml files (because they have IE 10 native) I discovered that the following flag was missing from the Windows 8 & Server 2012 unattend.xml files:

<IEWelcomeMsg>false</IEWelcomeMsg>

So I simply commented it out like so:

Re-ran my test deployment and it was 100% successful with zero errors.  Hope my time spent saves someone else some grief!
