The teams that still use centralized version control, such as Windows and Office, are either using Team Foundation Version Control (TFVC) or Source Depot (an internal tool that was built using a source code license of Perforce).

The developer division (DevDiv) currently mostly uses TFVC. For the open source projects this doesn't make a lot of sense though, which is why most these are moving to git.

Of course, we're a big company so you'll also find Mercurial and SVN, especially in MSR. I really hope that you don't find SourceSafe anymore though :-)
