BEST -- is to ghost the whole C
it is so important, as it can start as a fresh copy, whenever you want it
take too long to fix some small problem, restore from a ghost image, only take 30 min
it will also help you to try out some trial software too -- before you install those free trial software, you should do preparation
maybe time to get all the software noted and all the data moved, and then reformat the C drive, when you are really happy, -- one week after you become a happy user, you should then ghost it !!
