Microsoft showed off several new features, functions and tools at the Windows 10 event on Wednesday, ranging from updates to Windows 10 itself to unexpected holographic headware.
The scope of the event highlighted Microsoft's ambitions for Windows 10, which is seen as a make-or-break upgrade to Windows, especially in light of the flop that was Windows 8.
To help you get a handle on all the key announcements, V3 has put together a top 10 of what we thought were the biggest developments. What do you think of Windows 10? Let us know below.
10. Return of the Start menu for real
We've lost track of the number of times people have declared the Start menu and the Start button to be 'back' since Windows 8 was introduced, but it is happening for real with Windows 10.
The desktop will be the default workspace once more (at least on PCs), with the Start button at the bottom left of the taskbar where it always has been.
Pressing this will deliver a Start menu that users of Windows 7 and earlier will recognise, but with a customisable space added for favourite apps and the Live Tiles of Windows 8.
This means that Windows 10 will deliver a better experience for existing Windows users, without losing the best new features introduced in Windows 8.
Once again, Windows 10 is shaping up to be what Windows 8 should have been in the first place.
