Buying "corporate Windows, you do not purchase Windows, you buy the upgrade. Ie I can not say that you bought Windows. And this update – a useless load, if you no where to be updated. It does not give you the right to use Windows, if you have no previous product from which you can be updated. Q: Now I understand.
I hope very much. Now, if, after all, it is not clear, a little theory. Licenses for right to use the product are complete and incomplete. As an established translation in Russian yet, use these terms, which in English often sound like this: Underlying License and Effective Full License. The typical, most common, and the most understandable part time license – a license to upgrade. Suppose you have a computer, on which stands a hypothetical software. License you have purchased a full on "software version 1".
Attention! Left – not a hardware-software scheme complex, a scheme of "binding" licenses to a pc, right – your rights. The license for the "software version 1" The right to use "software version 1" pc Next, you are legally purchased upgrade to the "Software Version 2" for this computer: License to upgrade to the "ON version 2 of the "right to use the" Software Version 2 "At the same time retain the right to use" software version 1, "License to" software version 1 pc Thus, acquiring a partial license to upgrade to version 2, in addition to a full license to version 1, you get a full license for version 2.

Thus, purchased a full five licenses for Windows xp Home oem, and there is a corresponding right to use five copies of Windows xp Home. Then the system administrator has convinced the authorities to allocate a budget for updating (Partial license) to Windows Vista Enterprise program. After that, the organization has emerged a selection for each of the five computers: use it with xp Home or upgrade to Vista. And what other rights, the organization is present, it is possible to any time to switch to one of the options. Or xp, or Vista. An example of a rare and unusual. Assume the software update (not the operating system) is put into a separate folder, and does not remove the previous version. In this case, you have the right to use the basic version, and updated simultaneously. If it is, of course, allowed the licensing agreement for the upgrade. And finally, a very common mistake: License to upgrade to "software version 2" No the right to use "software version 2, as also required the presence of a full license to" software version 1 "No license" software version 1 "PC And here's how it looks in the case of desktop operating systems Microsoft: Corporate license of Windows xp or Vista (always Upgrade) Using Windows on this pc illegally. No license for the product from which you can update your PC
