Windows does, for both NTFS and ReFS. It works flawlessly in my experience. You can enable deduplication with one PowerShell command.
I’m sure Microsoft would enable it for Windows 11, instead of just Windows 2022, if it didn’t eat directly into juicy margins on increased storage in an industry where product customization / personalization is like 10% of revenues but 40% of profits.
That one step would probably free up global exabytes of disk space.

It’s implemented on top of the filesystem as a background process that moves duplicate data into a “chunk store” and replaces the files with reparse points that route accesses to the deduplication driver. This is ostensibly to keep deduplication out of the write path for performance reasons. https://learn.microsoft.com/en-us/windows-server/storage/data-deduplication/understand https://learn.microsoft.com/en-us/windows-server/storage/dat...
