Microsoft will offer Windows 10 for free in July | Technology

Windows 10 will be released as a free update on 28 July, Microsoft has announced. It will be the last major release of the 29-year-old operating system before Microsoft switches to a "Windows as a service" system, which entails updates being rolled out when ready. This marks a change in Microsoft's business model. The operating system will be offered as a free upgrade for users of Windows 7 and Windows 8.1 within the first year. Each version of Windows has cost upwards of 100, although the majority of Windows users receive new versions of the operating system when buying a new computer, and not by upgrading the software themselves.
