I use imaging with unattended install. When you have to support over 1000 PC's, you better have your hard drives imaged ahead of time. (I have 12 pre-imaged HDD's setting on my desk right now). And since my single master image works in any of our 15 different model PC's, all I have to do is replace the HDD and the PC is fixed in 5 minutes! I do not have time to install OS's & programs the old fashion way. I have been using DriveImage with some multi-imaging software from multixpimage . Having to only maintain 1 image is great and I can update it in less than 1 hour.
