The US Department of Defense (DoD) has announced a contract worth an estimated $1.76bn for Microsoft Enterprise Services.

The contract, which is set to run for five years until 10 Jan 2024, will see the Windows giant supplying the DoD, the US Coast Guard and intelligence community with a variety of services, such as support for tools, access to knowledgebases and the slightly ominous “custom changes to Microsoft source-code when applicable”.
