Microsoft has tightened Vista Transfer rights and you will be able to transfer Vista legally to only one PC other than the one you buy Vista for.
Windows General Manager Shanen Boettcher said that this change will make sense because the lifetime of the PCs is getting longer and users will not need to transfer the license to more than one computer during the time that OS is the latest one available.
However, some users say that this may encourage Windows Piracy among users who update their systems on a regular basis.
But to take care of the piracy Windows has launched Antipiracy feature in Vista and the users will have to verify that their version of the OS is authentic with a software license key within 30 days of its activation failing which they will not be able to use certain features of the PC.
