Microsoft also said its new tablet and smartphones will come with Windows Hello, an automatic biometric sign-in option introduced earlier this year.
The feature allows users to scan their face, iris or fingerprints to verify their identity and give them access to Windows phones, laptops and personal computers.
Windows 10, launched in July, is part of Microsoft’s push to win a bigger share of the market for tablets and smartphones, now dominated by Apple Inc and South Korea’s Samsung Electronics Co Ltd.
