Windows 7 install trick can save cash
Do a "clean" install using cheaper upgrade editions

Users can do a "clean" installation of Windows 7 using an upgrade licence to save $80-$100 over the price of a "full" edition, a popular blog reported today.
According to Paul Thurrott, who writes the Supersite for Windows blog, Microsoft's upgrade media and product keys can be used to do a full installation of Windows 7 on PCs that do not have an earlier version of the OS.
Microsoft's Windows 7 upgrades are designed to do "in-place" or "custom" installs on PCs running Windows XP, Windows Vista or one of the preview editions of Windows 7. But Thurrott said that a few simple steps lets users install upgrade editions, which are considerably cheaper than the full versions designed for fresh installations.

Windows 7 Home Premium, for example, costs $119.99 (£79.99 on the Microsoft EMEA website) as an upgrade, but $199.99 (£149.99) for the full edition, a difference of $80 (£70). The full versions of Windows 7 Professional and Windows 7 Ultimate, however, cost $100 more than the corresponding upgrades. (In the UK, Windows 7 Professional costs £219.99 while Windows 7 Professional Upgrade is £189.99, a difference of £30).
Nearly three years ago, Thurrott showed users a similar trick with the then just-released Vista; that technique, however, required users to install Vista twice.
Today, Thurrott spelled out how to conduct a clean install using a Windows 7 upgrade licence. The process requires users to install but not activate Windows 7 with the accompanying product key. After the installation is completed, users must make a minor change to the Windows registry, use the Windows "rearm" command, then reboot.

No you won't have a legal copy. That's what I'm talking about. If you use a software in a way that violates the EULA (for ex. by installing an upgrade version onto a clean machine, by hacking it), you lose all rights to use the software. Also you might face charges due to circumventing a scheme that's sort of a copy protection (which would prevent you from using the software in a non-EULA-conformant way, by checking whether it's installed on a clean machine or not). So, it IS illegal.

If I do that hack with an upgrade version, I have a legal copy of Windows 7, which is activated. If I download Windows 7, I have to find a crack for it. That's the big deal.

So what's the big deal about this? If you install an upgrade version onto a new machine, with no Windows on it, your installation will be illegal, as you don't own the "upgrade base". That said you could just as good illegally download a copy of a full version of the Windows 7 you want and install that. Would be just as illegal, but even cheaper and even easier to install, than the upgrade version with the hack.
