How can I verify that a .exe file is built for 64 bit on Windows ? I am used to Linux where I can simply use the ‘file’ command to see this.

Take a look into the file using a HEX editor. There’s a
PEmagic signature somewhere after the DOS stub, and the platform ID is close behind (some bytes later). For 64 bit builds, it is0x8664or so, which is quite easy to spot.
