Git, the open source distributed version control system created by Linus Torvalds to handle Linux’s decentralized development model, is being used for a rather surprising project: Windows.
Traditionally, Microsoft’s software has used a version control system called Source Depot. This is proprietary and internal to Microsoft; it’s believed to be a customized version of the commercial Perforce version control system, tailored for Microsoft’s larger-than-average size. Over the years, Redmond has also developed its own version control products.
