Windows 7: Windows 7 Upgrade with Vista

I have Windows Vista retail version installed on a desktop pc and two laptops that had Vista installed on them. I am buying Windows 7 Home Premium Upgrade Family Pack to install in my desktop and laptop. I plan on doing a clean install. Can anyone with the install ? My main concern is the the activation keys. I have the Vista retail disc for for my desktop and the recovery disc for the laptops.
Thanks for any help,

I don't understand the question.

The current word is that to use the retail upgrade license of Windows 7, a qualifying OS (XP or Vista) must be installed and activated on the machine. A factory pre-installed version of Vista qualifies. You have the option of doing an upgrade-in-place of Vista, or a "custom" (clean) install. The only problem I know of with the custom install is that the old installation is moved into a windows.old folder. That's not a problem if you have enough hard disk space to contain the Windows 7 installation plus all the old stuff. (You can use the Windows disk cleanup utility to get rid of windows.old later, if you wish.)

The "family pack" is three Windows 7 Home Premium retail upgrade licenses (keys) sold at a discount, I believe.

(You only get one set of install disks. I suggest making backup copies of them immediately. They aren't copy protected, if they are like every othe MS OS install disk I've seen.)

Your post reads like you wish to upgrade three machines, total. It sounds like you plan to use the Family Pack as Microsoft intended.

Thanks bobkn for the help and quick response. Yes I do plan on upgrading all three machines.
