Just a wild guess on my part but I think the percentage of users who care about 64 bit is in the single digits
I don't know what you mean about "caring" about 64-bit.
But, as you're "wild guessing', I'd like to introduce a fact: since 2013, all laptops sold in Italy have been with a 64-bit OS, even the ones with only 4GB of RAM.
Care or not, if your computer is newer than three years, chances are, they DO HAVE a 64-bit OS.
Just sayin'...
