Adobe reader 9.0关联文件

1、在要打开的文件上，点击右键--》打开方式--》选择Adobe reader（如没有，进入安装目录../Adobe/Reader 9.0/Reader/AcroRd32.exe)，这时文件图标可能没有关联完美。

2、在第一步之后，右键点击文件--》属性--》常规--》更该，再次选择Adobe reader就好了

上述不行的话，网上下载的一个办法如下：

装好adobe reader后不能自动关联PDF文件，而且手动关联后PDF的图标显示的也不正常，图标为一个白边中间是一个红色的方形图案，很难看。

运行regedit进入注册表，删除注册表中的
HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Explorer/FileExts/.PDF 项，然后将以下内容保存为 REG 文件双击导入：
