For very old Windows installations you may need a 32 bit Windows version.
Users running on ARM-based systems (e.g. Microsoft Surface tablet) should get an ARM Windows version. You will know if you are running one of these. If you are not sure then you should not download this, get the standard 64 or 32 bit build (x86) instead.
