As an open-source software pioneer, Munich spent years moving away from Windows, but now politicians are debating a report that suggests the city could eventually abandon Linux. A report on TechRepublic adds: If the authority ruling Germany's third largest city backs proposals to make Windows 10 and Microsoft Office available across the council, it would be a significant step away from open-source software for an organization once seen as its champion. Over a nine-year period starting in 2004, the council moved about 15,000 staff from using Windows and Office to LiMux -- a custom version of the Ubuntu desktop OS -- and other open source software. At the time, Munich was one of the largest organizations to reject Windows, and Microsoft took the city's leaving so seriously that then CEO Steve Ballmer flew to Munich to meet the mayor. Now a report commissioned by current mayor Dieter Reiter to help determine the future of IT at the council has outlined a project to make Windows 10 and Microsoft Office available to all departments, and give staff the choice about whether to use Windows or LiMux.
