On its advice on its Windows 7 support page, Microsoft says: “For most Windows 7 users, moving to a new device with Windows 10 will be the recommended path forward. Today’s PCs are faster, lightweight yet powerful, and more secure, with an average price that’s considerably less than that of the average PC eight years ago. We recommend that you don’t install Windows 10 on an older device, as some Windows 7 devices are not compatible with Windows 10 or could experience reduced feature availability.”

Windows 10 Home edition costs £119.99 for a single license, which is valid for one PC. And that’s the cheapest available option. The price to upgrade your PC spirals to £219.99 for Windows 10 Pro and a jaw-dropping £339 for Windows 10 Pro for Workstations. If you’ve got children with their own laptops for schoolwork, or a few laptops or desktop computers at home, this could become a very expensive week. And a nice little earner for Microsoft.

That said, some claim there are still ways to update to Windows 10 from a licensed copy of Windows 7 or Windows 8 to Windows 10 for free.
