You can`t upgrade to 64 bit. You have to reinstall with a 64 bit installer. Do you have a windows key ?

You can't do an upgrade-in-place from any 32 bit version of Windows to a 64 bit version. You'd have to do a clean install.

The main downside to that is whether you have any pre-installed software that you'd like to keep. There would be no practical way to transfer that to the new Windows installation.

It's aimed at getting a bloatware-free version of Windows, but it will serve in changing to 64 bit.

I'm about to buy a new laptop from Costco with Win 7 Home Premium. On my old (now smashed) laptop I have a Win 7 Ultimate install. Can I just use the Ultimate serial key to do the Anytime Upgrade on the new machine? I keep reading that I need to buy an "upgrade key." Thanks
