Microsoft Corp faces a coordinated investigation by European privacy regulators after it failed to do enough to address their concerns about the collection and processing of user data with a series of changes to Windows 10 last month. 

European Union data-protection officials sent a letter to Microsoft saying they remain “concerned about the level of protection of users’ personal data,” according to a copy of the document posted by the Dutch watchdog Feb 21. Regulators from seven countries are concerned that even after the announced changes, “Microsoft does not comply with fundamental privacy rules.”
