I have been looking for release of Vista for long time and tracking the related news. The latest observance is about the EULA of Vista where the limitations imposed by this license are discussed.
According to Vista’s End-User License Agreement (EULA), you can perform benchmark testing but you can’t disclose the benchmarking results. In Vista Home EULA,
9. MICROSOFT .NET BENCHMARK TESTING. The software includes one or more components of the .NET Framework 3.0 (“.NET Components”). You may conduct internal benchmark testing of those components. You may disclose the results of any benchmark test of those components, provided that you comply with the conditions set forth at http://go.microsoft/fwlink/?LinkID=66406.
Secondly, you can assign software license only twice which means, if you decides to upgrade to other machine, and transfer the license to second machine, you are all done. That’s it. Now you can’t use that license again.
a. Software Other than Windows Anytime Upgrade. The first user of the software may reassign the license to another device one time. If you reassign the license, that other device becomes the “licensed device.”
b. Windows Anytime Upgrade Software. The first user of the software may reassign the license to another device one time, but only if the license terms of the software you upgraded from allows reassignment.
It is going to be a big game other way round!
