C# Window7任务栏缩略图小工具

程序的实现原理：

 

　在注册表目录HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Taskband下新建几个键:MaxThumbSizePx, MinThumbSizePx, ThumbSpacingXPx, ThumbSpacingYPx, TopMarginPx, BottomMarginPx, LeftMarginPx, RightMarginPx 分别用于控制缩略图尺寸, 两个缩略图直接的边距, 还有缩略图中内容的上下左右边距

　　在注册表目录HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced下新建一个键: ExtendedUIHoverTime

它用于控制缩略图显示的延迟时间(单位是ms)

　　每次更改完注册表的信息后, 要看到效果不需要重新开机, 只需要关闭explore.exe, 再重新打开即可.
