P2V of Windows Server 2003 using OEM License

When you P2V (Physical-to-Virtual) Windows, it will want to re-activate Windows due to hardware changes.

MDT Win7 Deployment with IE10 Fails

Windows could not parse or process unattend answer file [C:\windows\Panther\unattend.xml] for pass [specialize]. That's what you'll see if you try to deploy a MDT image of Windows 7 that you captured via "sysprep and capture" with Internet Explorer 10 on it, then tried to deploy. Seems…
