I cleaned up all icons on my PC desktop window..
PC desktop metaphor has played an important role for productivity of people since two decades.
My desktop use has been a mixture of short cuts of applications and working documents.
After I upgraded my Windows to 10, its start-up menu has a duplicated role for application short cuts. I moved those short cuts on Desktop to start menu. Windows 8 tile start window could play the same role.
On the other hand, I use a Dropbox folder as my working document repository, because I access them from multiple devices. Dropbox synchronization is much faster and stable than One Drive or Google drive. I don’t need short cuts for them.
So I don’t need desktop window any more even of desktop PC which is not tablet.
