>Sometimes, from the desktop, I use the right area to pull out the vertical content for Search, Share, Start, Devices and Settings. Once I go in one of those options, I will be in the Metro area. From there, I can go, for example, in the list of install applications by scrolling down or right. But, it is not easy to know once to make the desktop appears back. I always click on Control Panel link which makes the desktop appear but with the Control Panel dialog which I have to close to get my desktop. Basically, I work 100% of the time in the desktop mode. I have over 100 icons for the development, management and so on. I am pretty sure someone knows the trick to get back to the desktop as is.
