Besides, this isn't a technical limitation, this is an imposed limit by Microsoft. They want you to purchase a more expensive version to use more memory
32 and 64 bit versions of Windows are the same price. The same license key even works. If you purchased 32 bit and want to run 64 bit, the media is available for basically the cost of shipping. Otherwise, you can source media elsewhere and use your existing key on that computer.
