Here are some interesting facts about Windows.

— Windows is currently the OS on 1.5 billion PCs.

— 77% of businesses with Windows still run Windows 7 on some or all of their PCs, because Windows 8 and 8.1 were/are so reviled.

— Only 18% of companies deployed Windows 8 or 8.1 on their computers.

— Because of the failure of Windows 8 and 8.1, there is a huge pent-up demand for an upgrade path.

— Windows 10 will be launched on July 29, 2015, and it will be free for people running Windows 7, 8, and 8.1.

— 60% of IT departments have already tested Windows 10, and 73% plan to adopt Windows 10 by 2017.

— Windows 10 will actually have a Start button, just like in Windows 7. Amazing, but the more things change, the more they stay the same.
