Re: Vista Home Premium 64 bit Upgrade from Vista Home Basic 32 bit operating system

Hi, Archquark.

Be sure your neighbor knows that ANY transition from 32-bit to 64-bit - or vice versa - will require a "Clean Install". That means a reformatting the partition, installing the new Windows, then re-installing all applications from their original media. Data can be backed up and restored. But most apps, even if the files are in place on the HDD, will need to be reinstalled so that the new Windows can make the necessary entries in its new Registry.

This "clean install" requirement is because of the hardware and driver differences between 32-bit and 64-bit. It is independent of any licensing issues or even about an upgrade to Premium or to Win7. (Win7 should be available at retail on October 22, 2009.)

My neighbor bought a Compaq Presario with an AMD Athlon 64 bit processor which came installed with Windows Vista Home Basic 32 bit operating system. If he buys the upgrade to Windows Home Premium will the disk recognize he has a 64 bit processor and install the 64 bit operating system and not just upgrade to 32 bit Vista Home Premium system.
