(A bit off-topic)
Q: We need to roll out Win7 images using Microsoft Deployment Toolkit 2010 (MDT 2010), but our PCs are all OEM builds - so no media. Can we get a single Win7.iso (w/SP1) from MSDN and use it to roll-out our customized Win7 replacements-for-WinXP-PCs using a different Product Key for each one?
(BACKGROUND: Our OEMs are (now) Windows 7, but the manual process to add out apps, change settings, etc. takes about 3.5-4 hours. Despite checklists, variances occur. My thought is to use the Windows Product Key off the sticker on the PC case. That way it ought to be legal to re-use the MSDN .iso throughout the process [about 500+ PC's to retire and replace with Win7 in the next few years.])
