Microsoft work-around allows clean install of Vista upgrade

Microsoft provides instructions to do such a thing, according to IT hack Paul Thurrott here. But it may also want to keep it quiet since upgrade versions are around a third cheaper than full Vista versions.

Thurrot posted a work-around that advises users not to enter the product key first time around when installing with an upgrade CD. This will get the OS onto the system.

Users then have to run the installation file again from within Windows Vista, enter the registration key and essentially upgrade the Windows Vista installation with another Vista installation. µ
