Here are a couple of Microsoft management tidbits to close out the week.

A couple of months ago, Windows veteran David Treadwell moved to Microsoft's Cloud & Enterprise team for a new, unspecified job. Now we know what Treadwell will be doing: He is the new Corporate Vice President of Identity. (Thanks to the tipster who told me and to a Microsoft spokesperson for verifying the news today.)

Twenty-six-year Microsoft veteran Treadwell said in a note in July that CEO Satya Nadella had asked him to leave Windows to take on a new role in Cloud & Enterprise. Most recently, Treadwell had been the Corporate Vice President in charge of Windows Engineering program management.

As part of this latest move, Microsoft is splitting the Identity and Security unit into two separate units, according to sources. While Treadwell heads Identity, Bharat Shah is now the Corporate Vice President of Security, I've heard. Microsoft officials would not comment when I asked about the division of the Identity and Security functions.

In other job (and security-related) news, Brad Smith is now President and Chief Legal Officer at Microsoft. Smith's most recent title was General Counsel & Executive Vice President, Legal and Corporate Affairs.

There are no changes in Smith's direct reports or other organizational changes as a result of the move. Smith will be working more on cross-company issues around engineering, public policy, legal and corporate social responsibility and do more to represent the company externally.

Smith will continue to lead in Microsoft policies around privacy, security, accessibility, environmental sustainability and digital inclusion, and will remain a member of the Senior Leadership Team. Nadella announced Smith's new title via an internal e-mail on September 11.

Smith is not the only Microsoft manager with "President" in his title (example: Judson Althoff is President of North American Sales for the company), but he is the only President with cross-divisional responsibilities, as far as I am aware.
