I have made a video to show all the features that are new to Windows 8.1 (Blue). This is the latest build that has been leaked recently.
It brings some nice features like an improvement to the Snap-View and a feature called "Kiosk-mode". Everything is explained in the video.
I am sorry if I sometimes forget the words and things are hard to understand, because obviously English isn't my first language. Hope you like it.
You can find the video on YouTube
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
