Switzerland's Federal Data Protection and Information Commissioner (FDPIC) concluded an investigation into Microsoft’s Windows 10 operating system, following the U.S. company’s decision to adopt recommendations for improving data processing transparency. The Swiss regulator’s investigation had found data protection gaps under Swiss law.

"The technical implementation of the modifications requested by the FDPIC will be carried out worldwide as part of the two Windows 10 software releases planned for 2017," the FDPIC said.

In its 2015-2016 annual report, the FDPIC said the system's quick installation or "get going fast" option automatically activated nearly all data transfer and access processes, which meant user data, including location details, browser and search history, keyboard entries and nearby WiFi networks, automatically went to Microsoft.

In concluding its investigation, the FDPIC said the Windows 10 "quick access" and "customize settings" pages had not fully met transparency requirements. Information was lacking on the content of browser, feedback and diagnostic data, as well as on the length of time that transmitted data would be stored, it said.
