Before the releasing of windows 10, Microsoft had announced it’s technical preview of windows 10 operating system (OS). Windows 10 is coming on July 29 as a free upgrade to Windows 7 and Windows 8.1 users (for one year). Microsoft’s latest OS will be available to pre-order in the coming weeks when it launches in 190 different markets around the world.



Microsoft’s Executive Vice President of Operating Systems Terry Myerson announced in January that Windows 10 will be free for existing Windows 7 and 8.1 users for its first year. Microsoft also confirmed that the two most recent Windows versions will be able to upgrade to Windows 10 directly. However, if you’re not eligible for Microsoft’s upgrade program – those who upgrade after the first year free offer, or those running a non-genuine Windows version or one older than Windows 7 – Windows 10 Home will cost $119 (about £78, AU$156) and Windows 10 Pro will cost $199 (£131, AU$262) per license. Windows 10 Home users who want to upgrade to Pro will have to pay an additional $99 (£65, AU$130) for the Windows 10 Pro Pack.

The Microsoft has promised that it will support those who scored a free upgrade to Windows 10 with security and system updates for the lifetime of those Windows devices. Windows 10 will be available in 7 versions, far more than one would have expected in the first place. While IoT, Mobile, Home, Enterprise and Professional were already confirmed, Mobile Enterprise and Education were unexpected. In comparison, there were only four versions of Windows 8.1 and one of them was Windows RT. Microsoft clarified the free upgrade offer for Windows 10, adding that Windows 10 Home and Pro will be available for free to Windows 7 and Windows 8.1 users that have appropriate licenses.

For the more experience or foolhardy users in Microsoft’s fast ring, they’re already up to preview build. The new build isn’t as stable as the slow ring’s aforementioned latest release, but introduces new features like the New Tab feature in Microsoft Edge that the company showed off during its Build 2015 show. However, these builds are always less stable than the more tested slow releases.
