Hey Micro,
If when you said you were ghosting, you meant Norton ghost, then you are already doing exactly what I was describing when discussing imaging in the folding forum. Saving an image as a backup file, Ghosting is just Symantecs coined term for the same thing!
Here's what I do, if you are interested. Any new machine I get, or after and OS upgrade, I install windows and get all the drivers up to date, then let windows updates do its thing until all updates are in place and current.
Then I image it, so I have a base image to revert back to that does not require windows updates etc like a fresh install.
Then I install all programs and customize/configure till my hearts content, then make another image with everything installed. Another fail back point before anything is done online, and any risk is assumed.
After that, I just make an image every 2-3 months, saving the last 3, then delete any older ones to save space!!
