I've noticed that some people in this particular section of the website seem to think one (or more) of the following things:
1) An alpha/beta/RC version of Windows/Service Packs/Office (et al) is not copyrighted.
2) Its safe to use alpa/beta releases if you've got them from Microsoft, but don't belong to the alpha/beta group.
3) Its "ok" to make multiple copies of your alpha/beta software to give to your friends/family members.
Well, for those of you that think one of the above, you're quite wrong.
Microsoft software (and pretty much any copyrighted software) will usually come with a license (typically called a EULA, or "End User License Agreement") which states the terms and conditions under which you have been granted use of the software.
1) The EULA is applicable to any and all versions of software, whether it has been supersceded by a new release or not (at least until the license changes). This means, that alpha/beta/RC versions of Microsoft (and indeed any copyright protected software) are indeed copyright, and protectable under law.
2) You are not allowed to download alpa/beta/RC software from Microsoft unless you have been given permission to do so by Microsoft. You can request to become a member of the Betaplace testing community (this however does not automatically grant you immediate license to download the software though). You are licensed to download and use software from Betaplace once you've been invited to join a beta test.
3) You are not allowed to make copies (or leak) software to your friend/family/the Internet. Doing so is a direct violation of the EULA in which you've installed and or are using the software.
Microsoft have every right to protect the copyright on their software, whether it is alpha, beta, or release candidate (or other). This is also true of any other copyright protected software.
