I did not say 2008; I said 2012 or windows 8. Basically, Windows Server 2012, and some of the more business-ey versions of windows 8 will have a feature you can turn on in add/remove windows features. This feature will install a windows service that is configurable.
This service is the deduplication agent and it runs on a daily (customizable) schedule. It works by comparing new data blocks created or modified since it's last deduplication pass with old blocks. When it finds that a new block contains the same data as an old block, the block pointer is changed to the old block and the new block is freed. This is basically how all deduplication agents work, though some use hash trees, real time scanning, or hardware offload hash trees (as in the case with enterprise grade SAS that do realtime deduplication passes as data is written).
