x64

I've just got a new laptop with Windows 7 x86 Home Premium installed, however I ideally I'd like to be running a 64-bit operating system:

Is my Windows license key "generic" (in that it entitles me to install either a x86 or x64 edition of Windows), or does this licence key specific to the x86 version of Windows?
Is there any way of me installing and running Windows 7 Home Premium x64 using my x86 license key?
