Is it possible to put some text on Windows 8 desktop without adding text on background image? Can I write something to text file and then ask windows to show it's content on desktop? How to do this?

For what you want - you need a user defined field pointing at a text file. Annoyingly, if you do this, it will always show the identifier.

No. Personalization of background for desktop id made of images. You can search for a simple image editor and add your text to an image. I don't know, but you may try to look for desktop gadgets that show quotes or post its, and this way you will have a text on desktop too.
