I have many computers in my office from Dell. One of the computers is a Dell INSPIRON D531 which came with Vista installed. I have many other Dell laptops and desktops which came with Windows 7 ultimate and some of which are scrap now, but I do have the DVDs of the OS.

Can I use the Windows 7 DVD which came with other Dell on that INSPIRON to upgrade Vista?

Will it ask for a key or activation? I want to save my time and start to upgrade Vista to Windows 7 once I am sure. Any suggestions?

Just because you have the media to install an operating system does not automatically mean you have a licence to use said operating system.

When installing it will ask for a product key, which will either be on a card for a retail copy of Windows or on a sticker on the machine for OEM copies of the operating system. You cannot install an OEM copy of Windows on any other machine than the one on which it is already installed. You also cannot activate a Vista key in Windows 7.

Unless you have specifically bought an upgrade from Vista to Windows 7 you are likely to be using it illegally.

As an aside, Windows Vista is actually surprisingly usable provided that it has sufficiently powerful hardware. On underpowered hardware it can perform less than spectacularly.
