Does WIndows 10 support 32 Bit UEFI mode ?

Specs: Win 10 , I7
During my work I have previously successfully deployed PC's with several Computers with UEFI Booting with GPT partitioning for a while now - due to its advantages ( I understand UEFI supports 2TB+ drives and is quicker to boot ) , this UEFI booting was also influenced by being supplied with more modern motherboards which do not natively recognise MBR partitions

It seems the general concensous is that UEFI is a technology that only supports x64 Operating systems , is this correct?

We are being suplied with Netbooks which have 32GB SSD's and I would rather install X32/86 Windows to save a Few GB . I have created a Dual X32/x64 Win 10 Image with UEFI boot and GPT partitioning , however this throws an EFI error when I run the 32 bit install but runs fine on X64 ( Using Rufus )

I also tried creating and running a MBR with CSM for UEFI but Windows does not recognise the SSD


I spoke to ASUS , they rekon their netbooks support 32Bit UEFI Win 10 OS , so am a bit lost


This is an Asus E402MA-WX0055T

Meh , I feel like piggy in the middle here

Asus says they support 32 bit uefi

Windows states that 32 bit compatibility is dependant upon manufacturer's bios

Meanwhile I have a laptop that wont install 32 bit in MBR or UEFI boot . WHile on that note I have never been able to boot in 32bit UEFI - Has anyone else?

"been able to boot in 32bit UEFI"
Never taken any notice.

64-bit requires double the memory as well.

Most new computers use 64-bit UEFI. But there are also some tablets using 32-bit UEFI, such as Dell Venue 8/11 Pro, Toshiba Encore, Acer Iconia W3/W4, Lenovo MIIX 2, Lenovo ThinkPad Tablet 2 and ASUS Transformer Book T100/T300.
