Windows does, it's called Winpe. It's what the Windows installer media runs, but you can (could?) create your own images that boot straight to desktop. Winpe images that included a third-party screen reader were somewhat popular among the blind community at one point, before Narrator (the built-in screen reader) got decent and Microsoft started including it and related components in the installer. I think the original rationale behind this feature was the ability to make custom disks with data recovery tools and such. Mac OS can boot from external volumes too. It's not a traditional live image, the volume is usually writable and it's a real copy of Mac OS. We're probably talking actual HDD or SSD portable hard drives here, not flash drives, Mac OS isn't that small. You need a Mac to run one of these of course. No idea if this works across computers on Apple Silicon. The new Macs store a lot of the encryption and boot policy stuff in the SE, so I have no idea if booting an unrecognized system would actually work. |

It's "Windows-to-Go", introduced in Windows 8.0 which had the full Windows functionality contained on the USB stick, if the bootable stick met the high-performance requirements and had firmware indicating to Windows that the USB stick was not a "Removable Device".
This was gradually deprecated for the most part:
