这个注册表项能否删除

注册表[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectDraw\Compatibility]
下面有很多看似运行过的程序名键和键值，绿色的部分能否全部删除？删除后会不会对系统有所影响？

如果可以删除，要保留Compatibility空键，其它键值全部删掉，BAT批处理该怎么写？
最后效果如下：

没必要删除。看名字是DX的兼容性项。

这些并非运行过的，默认安装就有的。 我系统里啥游戏也没装，一样有这些键值。

注册表里的东东不是高手不要动，最好用CCleaner清理注册表

爱拽不拽

备份下系统，备份这些注册表项，然后删除试试。不过一般除非大量使用软件，用了几个月甚至几年的电脑，才建议用工具清理注册表，不建议自己手动删除

似乎是指那些设置了兼容模式运行的程序，删了没关系。
