It seems like just yesterday that Microsoft pushed out Windows 8, a bold touchscreen friendly vision of the future of computing.
And now, Microsoft is gearing up to launch Windows 10, an OS that is so fresh and so revolutionary that you won't even think to ask what happened to Windows 9.
I'm Donald Bell, and this top five, we're counting down the best reasons to get excited for Windows 10.
Starting off at number five, hardware detection.
We knew if 10 knows whether it's being installed on a desktop or a tablet or a hybrid or an all in one, and emphasizes its desktop or mobile features accordingly.
Your desktop is now a desktop again, and it looks suspiciously like Windows 7. At number four, Snap Assist.
Now that our Windows desktop is back, Windows will help you group and organize snapped windows together across multiple desktops.
If you get all OCD with your desktop organization, Snap Assist is a dream come true.
Windows will even suggest which apps group well together.
I'm not sure if you'll actually be more productive, but it looks so clean.
Coming in at number three, you can now run new universal apps in the desktop view.
No more choosing between desktop apps and launcher apps.
You can now run any app in the desktop view.
And instead of the newer apps all running at full screen.
You can now resize their window just like any other app.
At number two, Task View.
Just like Expose on Mac, you can now take a birds eye view of all your open apps and desktops and juggle between them.
Now you pick an app you like, then Snap Assist kicks in and helps you pack the perfect Bento box of productivity.
But the number one reason why an upgrade to Windows 10 will have Microsoft fans beaming with pride, the triumphant return of the start menu, bigger and better.
You can customize it, you can pin apps into the launcher, resize icons.
And search, you can search from the start menu again and it's the same universal search found in the Windows 8 Metro launcher.
So there you go.
Five reasons Windows users should get excited for Windows 10.
Now if you've been sitting on Windows 7, this could be the OS that will get you upgrading.
