Today's theme is a simple and fun feature in Windows 7, even the aunts who cleaned the next door know that this is the new "News in Windows 7" wallpaper, the official name is "ldquo; desktop background slides" ”.
In the era before Windows XP, we can only choose a static picture as the desktop background, the system comes with obviously not enough personality, and it will inevitably be aesthetically exhausted when you download it for a long time.
Friends who have used Windows Vista must remember a very popular feature at the time, "Windows DreamScene", by using high-definition video as the desktop background, the previously static desktop began to move, full of vitality. Unfortunately, this feature is only a value-added feature for the flagship users, and the high-definition video resources suitable for the background are still very limited. Another problem is that the video file will always play the computer's CPU or graphics computing resources, increasing system consumption. Electricity is not conducive to environmental protection and energy conservation.
So, in Windows 7, Microsoft no longer provides Windows DreamScene, instead it automatically replaces the desktop background function, users can select many photos at the same time, the system automatically switches after a predetermined time interval, to achieve a loop Play. This design not only solves the problem of static desktops, but also does not lack the available materials like Dreamscene, and it also occupies very little hardware resources. As long as you are a Windows 7 Home Premium or higher, you can use the “desktop background slideshow” function.
However, if you only say this today, it is too unsightly. Here, I would like to introduce you to a hidden trick in Windows 7 —— set the transition time when the photo is replaced. Everyone knows that when changing the desktop background photos, there will be a gradual effect in order not to be too awkward. The transition time mentioned here is not the interval between changing the background of the next desktop, but the speed of this gradient effect when switching photos.
If you still don't understand, then try it yourself, seeing is believing:
1. Run regedit from the start menu and open “Registry Editor”.
2. In the tree structure on the left, expand to the location of "HKEY_CURRENT_USERControl PanelPersonalizationDesktop Slideshow", and right click in the blank space on the right pane to create a new "DWORD (32-bit) value". For “AnimationDuration”.
3. Double-click "AnimationDuration" to enter a decimal number, which is the duration of the transition effect, in milliseconds. For example, setting it to 10000 means 10 seconds.
OK, right click on the desktop and select “ next desktop background, the desktop will slowly transition to the next picture. It is spring now, when the evening sun sets, the blue sky will be dyed golden yellow and orange by the sunset, and finally it will gradually darken. How, now, you can have such a slowly changing effect on your computer. The feeling of busy study or work is calm and more comfortable. (This article Source: wbpluto's technology blog)
