I would be surprised if it did work. I think that each key might be unique to each disc (for home users at least) - to prevent piracy. I might be wrong here though

WRONG!

I would be surprised if it DIDN'T work! So long as your key is, in fact, legit, it will install and activate. Remember Vista's protection scheme checks product keys, and not byte code.

EDIT: I re-read your post, so my last EDIT was moot. Yes, so long as you dont change too much of the hardware on it, and so long as the seller hasn't transfered the license to a different computer.

You can also install Vista without a license and use it for 30 days.

You can use the key with any Home Premium disc. You're even allowed to buy another copy and change your key after it's been installed (don't know why they have this feature, but it can be useful if you need a quick install but don't have a new key handy).

Thanks to All who replied to my question. Unfortunatley when I double checked, the disk I have access to is NOT the home premium version as I thought, but vista ultimate. So I guess I'll have to try to find a home premium disc somewhere to use. But at least I have confidence that if I do find one it will work.

The ultimate disk will work fine. The product key is what determines which version of vista is installed. I know this for a fact as the notebooks we received for work have vista business license stickers on them but our corporate it group installed win xp on them. I bought a notebook drive and swapped it with the company's drive; installed vista business with my vista ultimate disk I have for my home desktop. Worked perfectly.

I think You should contact with the Microsoft Global Technical Deparment

Thanks or the tip Laser, I'll give it a try.

The Vista Ultimate disc did seem to work with my home premium key, just as Laser predicted. Thanks for the help.

Me too.
I installed Fedora on my ASUS laptop and it's lovely. But I plan to sell it now and I know it will sell much faster with Windoooooooooos.
Blew away the RP. Now I need a Vista Premium (I have the license) disk. It came with 32-bit which was stupid being that it's a 64-bit system.
I thought you could download Windows versions from Microsoft and make your own CD/DVD. I have a Microsoft professional account (not technet), but it does open more areas. But nagivating the site is making me rip my hair out.
Anyone have the link to downloading full ver Vista Premium 64-bit??????
I will be forever grateful and install any Linux version on your computer for free in return to replace Windooooos. HAHAHAHAHAHAHA!!!!
If I have to call the Microsoft robot I will slit my wrists.....
