Intel On a Windows Vista or Vindows 7 disk, all versions of the operating system are present, from Starter to Ultimate, and everything in between. So, if you want too upgrade to a more capable version of Windows down the road, all you need to do is pop the Windows disk in, let Windows Anytime Upgrade do its thing, and you're done. It seems like Intel is experimenting with a similar technology... For its processors.

Hm, what to think of this?

I have a hard time figuring out if I think this is a kinda good idea, or if I hate it with a passion. If there's no hidden costs (except the upgrade ending up being more expensive than having bought a faster CPU to begin with) to the end user, it could be OK...

As for crackability, this could be done pretty much 100% secure. There's already (public-key?) cryptographic verification in the CPUs for accepting microcode, and we know Intel has the capability of doing per-CPU unique numbers (remember the P3 days?).

Famous last words.

Seriously though you should really reflect on what you're about to say before making a statement like that. A free upgrade is enticing and will surely draw a lot of attention to cracking the Intel upgrade security. The problem with "100% secure" guarantees is that while something can theoretically be "100% secure" the devil is in the details. A lot of security schemes are broken because of poor implementation not poor cryptography.
