I'm a Windows newbie. What's the best way to upgrade from 32 bit Windows 7 to 64 bit Windows 7? The [microsoft docs](http://windows.microsoft.com/en-us/windows7/32-bit-and-64-bit-Windows-frequently-asked-questions) say I can't upgrade in one easy step, I have to save my data, reinstall from scratch, then move my data back in. Is there a slick and easy way to do the move-my-data-back-in part where Windows finds all my files and config and puts them in the right place?
