Dogs In Winter Theme Pack is provided by Microsoft to change Windows7 desktop backgrounds.
This package works on Windows 7 Home Plus, Professional, Enterprise and Ultimate editions. It contains ten photographs of dogs playing, running over the snow, chewing things and looking into your eyes.
Your system will open the downloaded file with the Control Panel, in the Personalize window. By default, it will set all the images in the package as the pictures to use as backgrounds of your desktop, using the default settings. Clicking on the Desktop Bacgrounds Link, you can choose which images to use, the position where they will appear, and the time they will stay before being changed for the next picture. If you want, you can choose to shuffle the list of pictures to use, to change the order in which they will appear.
The theme is configured to use the Afternoon sound scheme, that changes the sounds that Windows uses to notify about the system events with sounds played with a guitar. To uninstall this theme, you will just need to press the right button of the mouse while pointing to the Theme name, and select the "Delete theme" option.
