no and yes and no — the bios is actually uefi and it’s 64 bit. it will only boot uefi mode to 64 bit operating systems. windows can only recognize GPT partition tables when using windows uefi boot mode. our flash device has so many partitions it cannot use classic mbr partitions which allow for 4 primaries, one of those can be extended which allows a tonne of logical partitions inside. our android uses gpt and for solid reasons.
there is such thing as a custom hybrid-mbr-gpt where there’s an mbr table with mbr partitions in the middle somewhere of a gpt disk. flakily marked to not be tampered with, and custom set up with bios windows boot loader. the bios booted windows will not be able to see other partitions. and that’s IF fast-boot allow csm to boot bios operating systems and you want to spend 12 hours installing windows.
what I’m saying is that yes, 64 bit windows requires more ram — however, windows 10 is way better at managing memory than previous version .. task manager memory usage might not look like it, but that’s how good it is.
64 bit processors show obvious improvement with audio, video, cryptography, compression/decompression and all gaming.
