There are probably many people, who may remember that some versions of Windows Vista had an effective function called DreamScene. It allows to set video wallpaper in .wmv or .mpeg format as a desktop background. Instead of this Windows 7 has a wallpapers slide show. However DreamScene is not gone away, it was only deactivated and hidden deep within a system. In order to reveal the opportunity to use this function again, one may try a common utility DreamScene Seven. After the program is downloaded, it is necessary to run the file with administrative privileges (right button click is the run as Administrator). Then you have to select the button Install DreamScene. Now a new item Set as Desktop Background will appear in the Video File Context Menu, with the help of which it can be set as a desktop background. So it only remains to visit DreamScene gallery and choose an appropriate video clip for the desktop, there is definitely a wide choice - more than hundred of selective scenes. Foreseen moaning of some ascetics, I would like to conclude, that of course DreamScene profited nothing, but waste the system resources only. But from the other hand, if processor throughput increases constantly every year, why not to occupy it with something. Moreover if some window is open to the entire screen (or a game is running), replaying of movie comes to a halt and the system resources is not wasting.
