Microsoft has today claimed that Windows 10 is now running on 350 million PCs. While this number sounds impressive, growth rate of Windows 10 activations has seen a downward slope lately and Microsoft wants to get more and more users to upgrade to Windows 10 before July 29, when the free upgrade offer ends. Microsoft is also offering a $300 discount to students on purchase of Xbox One and Surface at Microsoft Stores.

We’d like to say a special thank you to each of you who have upgraded to Windows 10. With over 350 million devices now running Windows 10, customer satisfaction is higher than any previous version of Windows and customer engagement is also incredible with more than 135 billion hours of use on Windows 10 since launch. We’re pleased that so many of you are being more productive and having more fun with Windows 10. Your feedback has been a key input into the design of the Anniversary Update.

To celebrate, we’d like to make it easy for everyone to enjoy the great new features in the Anniversary Update. Our free Windows 10 upgrade offer is available until July 29, and we’re also excited to share a few additional special offers. Students can save $300 when they purchase an Xbox One and Surface at Microsoft Stores, or get a free TV when they purchase a Dell PC over $699*. Plus, consumers can get $150 off select HP devices or $100 off select ASUS and Samsung devices.
