[SOLVED] When I buy 32bit and want to change do 64 bit in a while...?

Hello Folks!
I got a question, im just before buying Win 7.
I want to buy the 32bit version now, because of Hardware limitations in my running system. But how is it when I got the 64bit Hardware in a while, can I download the Win7 64 bit version then and use the same licence key when I change the hardware in my PC?

Thanks for an answer!

If you buy an edition of Windows 7 that comes with 32 and 64-bit (Full, Upgrade, Student or Family Pack), the same license key works for both versions. You can only install one of the versions at a time, and you must reinstall Windows completely to switch.

Thank you for this information!
I'm planning to buy the student version, and with this information in mind i will do so now.


Thanks
