Awesome, So it wont increse the size of the final installation, just the size of eveyrthing thats on the CD? How much will it increase the size of the cd? couple hundred MB? Is nlite the only tool one needs to create a fully unattended install with all the latest servicepacks, hotfixes, & driverpacks? My understandig is it's not just a slipstreamer, but it also allows one to remove vast chunks of XP not needed. Is that pretty much it, or is there more to it? Apart from the default profiles for removal of componants etc. Are there 3rd party ones made-up be people who have tested their work? Cheers, Jed
