Bloomberg did an interview with Microsoft's vice president Yusuf Mehdi, in that interview he announced that over 300 million people use Windows 10 on a daily basis.
It is an interesting fact considering last year Microsoft announced it had 400 million devices active with Windows 10. Though such numbers always are to be taken with a grain of salt, the daily usage however should be fairly accurate.
The original goal for Microsoft was to have one Billion devices fitted with the OS, but that target seems a bit unlikely.
300 Million people now use Windows 10 Daily
