Win7 Desktop background slide feature: Desktop changes at any time

Today's topic is a simple fun feature in Windows 7, and even the next door cleaning aunt knows, this is the new "wallpaper Change" in Windows 7, the official name is "desktop background slides."

In the era before Windows XP, we can only choose a static picture as a desktop background, the system itself with the obvious lack of individuality, the download of their own to watch for a long time will inevitably aesthetic fatigue.

Friends who have used Windows Vista must remember the very popular feature of "Windows DreamScene", which used the desktop background of high-definition video, the previously stationary desktop began to move, full of vitality. Unfortunately, this feature is only for the flagship users of a value-added function, and suitable for the background of high-definition video resources or very limited, there is a problem is that video files will occupy the computer CPU or graphics computing resources, increase system power consumption, not conducive to environmental protection and energy saving.

Therefore, in Windows 7, Microsoft no longer provides Windows DreamScene, replaced by the automatic replacement of desktop background features, users can choose many photos at the same time, the system at a predetermined interval after the automatic switch to achieve loop playback. This design not only solves the static desktop uninteresting problem, and will not like DreamScene as the lack of available material, while the use of hardware resources are very few. You can use the desktop background slides feature whenever you are a user of the advanced version of Windows 7 home.

But if that's the only way to say it today, it's going to be a little bit too much to tell you about a trick hidden in Windows 7-Setting the transition time for a photo replacement. As we all know, when you change your desktop background photos, you will have a gradual effect in order not to appear too abrupt. The transition time is not the time to replace the next desktop background, but the speed of the gradient when you switch the photo.

If you do not understand, then try to do 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 margin of the right pane, and create a new DWORD (32-bit) Value, named "Animationduration".

3. Double-click "Animationduration" and enter a decimal number, which is the length of time the transition effect is to play, in milliseconds. For example, setting to 10000 indicates 10 seconds.

OK, now click the right mouse button on the desktop, select "Next Desktop Background", the desktop will slowly transition to the next picture. Now in the spring, when the evening sun sets, the blue sky will be in your unconscious in the sunset dyed golden, orange, and finally gradually darkened. How, now, your computer can also have such a slow change of effect, busy learning or work in the mood quiet down, a more comfortable. (This source: Wbpluto's Technical blog)
