What about upgrading the software? The software covered by this agreement is an upgrade to your existing operating system software, so the upgrade replaces the original software that you are upgrading. You do not retain any rights to the original software after you have upgraded and you may not continue to use it or transfer it in any way. This agreement governs your rights to use the upgrade software and replaces the agreement for the software from which you upgraded. After you complete your upgrade, additional software will be required to playback or record certain types of media, including DVDs.

If yes,
You would have NO original software.

yes i have downloaded it. thanks for letting me know, because i have been looking all over for it.
so i take it that if i installed wins 8 on my d drive it would still remove wins 7 from my c drive

thanks everyone
