The way I found to get the latest insider Windows builds onto a Raspberry Pi 5.
First setup Windows 11 on a supported RK3588 device. Then use that Windows installation with the Raspberry Pi uefi boot on an sd card.

I used wor flasher as other methods of flashing Windows didn’t seem to like the latest builds. You can’t register for insider updates on RK3588 or Raspberry Pi 5 as they are unsupported devices

Uefi links (bios for an SBC)

Notes

Apples switch to Arm has been incredibly fast partly thanks to Rosetta’s compatibility Layer

Office Chrome and Edge all run natively on Arm

Microsoft have observed this and created Prism
https://arstechnica.com/gadgets/2024/05/microsoft-says-prism-translation-layer-does-for-arm-pcs-what-rosetta-did-for-macs/
Prism like Rosetta for Mac 24H2 10-20% faster

Raspberry Pi 5 No longer getting updates

Orange Pi 5 plus stays on 23H2 at this time23rd May 24 (not compatible with insider builds minimum requirements not met’
