I have a laptop with Windows 10 32bit in it that my system would also be compatible with Windows 10 64bit but Windows shuts down every time before it has loaded Windows Installer from the USB.
Laptop: Pi 3540
CPU: Intel Core 2 Duo CPU P8600 (2.40Ghz)
This model Fujitsu Amilo Pi 3540 has problems with 64-bit systems. Both with Linux 64 bit and with Windows 10 64 bit.
I would leave it at 32 bits.
