未必就是盗版，Win7背景变黑或只能纯色其他原因
大家都知道，Windows7盗版系统如果被微软识别出，会将桌面背景变黑，俗称“黑你没商量”。
但背景变黑的情况未必只有盗版一种原因，还有可能是某些设置被人为“动了手脚”！导致——WIN7原管理员帐号不能更换壁纸，只能使用纯色壁纸，新建帐号正常更换

▲原因：轻松访问中心--使计算机更易于查看--删除背景图像，不知道被谁勾起来了
勾掉之后点击确定，即可正常显示且更改桌面背景了。
第二种可能：
原来的帐号不能更换壁纸了，只能使用纯色的壁纸，个性化壁纸不能更换。新建了一个管理帐号注销登录后却能正常更换。
原因可能是把桌面隐藏的两个配置文件desktop。ini删除了导致不能更换桌面，复原方法是：
在地址栏输入：
%USERPROFILE%\AppData\Roaming\Microsoft\Windows\Themes
找到TranscodedWallpaper.jpg ，将其后缀改为old，
即TranscodedWallpaper.old，然后同一文件夹下隐藏的slideshow.ini以记事本方法打开清空里面的内容保存，桌面上被删除的desktop。ini就回回来了，正常更换壁纸了。
