Hi,
Signed up just to say thank you for this solution. I have an MDT Environment that runs under a Systems Center Virtual Machine Manager Configuration, and for the life of me, couldn't get the capture to proceed beyond 11% without crashing (about 500-1000MB WIM Size).
Tried shutting the machine down entirely after the initial sysprep, then tried again, and confirmed the capture is now at 40% and counting! Thanks SO much for this solution.
