Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data at once. A 64-bit processor can store more computational values, including memory addresses, which means it can access over 4 billion times the physical memory of a 32-bit processor. That’s just as big as it sounds.

Yes, lack of ability to boot or execute any of the 64-bit files. For all intents and purposes, it is essentially impossible to execute a 64-bit instruction on 32-bit hardware, and while 64-bit Windows may have some 32-bit files, the main parts are 64-bit, so it won’t even boot.
