If you are on Windows 7, Windows 8.1 or Windows Phone 8.1, you will be eligible for a free upgrade inside the first year of Windows 10. Microsoft made the announcement this morning at an event on its corporate campus outside of Seattle.
On stage, Microsoft’s Terry Myerson pitched Windows 10 as a service, instead of simply an operating system that a user installs. Or, put more simply, the company views the next version of Windows as the hub of its various services.
