I would not say it is work of Microsoft.
Whatever FileSystem is flash memory formatted for,
internally it uses its own specialized filesystem for flash devices
( there are such ones )
or at least modified version of common filesystem.
It contains integrated memory controller chip to manage it.
The purpose is to manage "wear leveling" to get all sectors tired in the
same/similar speed. Some areas have extra backups.
Without it e.g. FAT32 File allocation table area would get damaged soon.
