Microsoft famously described Windows 10 as "the last version of Windows".
Unlike its predecessors, Windows 10 isn't expected to be superseded by a new release but rather upgraded over time, with Microsoft bolting on new features via regular updates - which home users won't be able to refuse.
That means even if you don't like Windows 10 now it should get better over time. That's good news - as, at present, Windows 10 seems more like an operating system with promise, rather than a must-have.
Of course, many of these criticisms should be tempered by the fact Windows 10 is free to the vast majority of users. As widely covered, anyone running Windows 7 or 8.1 will qualify for a free upgrade to Windows 10, which, providing they meet the system requirements, will be available via Windows Update.
