Microsoft is to open up the source code behind its server communication protocols, in an attempt to get the European Commission off its back. The announcement covers the source code behind the communication protocols for Windows Workgroup Server and Windows Desktop. Microsoft already offers 12000 pages of technical documents and 500 hours of free technical support to anyone applying for a license. Companies making software which interacts with Microsoft servers use those licences to make their products work properly with Microsoft ones. Such license-holders will now also get to look at the source code, but will not have the right to publish the code or include it in their own products.
