怎样为Win7下的无后缀文件设置一个默认打开程序

1、我们可以尝试通过修改注册表来强制搞定它。

2、正常情况，在注册表HKEY_CLASSES_ROOT下面能看到各种类型文件即后缀，但是没有 “.”,也就是说Win7没有为无后缀文件设置默认程序。我们要做的就是要建立一个“.”.

3、你不用自己建立了，挺麻烦，直接导入我做好的的注册表文件吧（看文章最后，那就是注册表文件）。导入完成后，你就能看到这个“.”了。还不能用，你需要在HKEY_CLASSES_ROOT/./shell/open（print, printto可选)/command/下面重新把你喜欢用的默认文本编辑器替换过来，我自己的路径你们不一定可用。

4、然后在任务管理器中关闭iexplore.exe的进程，再重建一次，这样新的注册表就生效了，现在去打开你们的无后缀名文本文件试试吧！

5、最后就是那个注册表文件，随便新建一个空白注册表文件比如test.reg，然后文本编辑器打开，把下面内容复制进去：

6、最后确认一点，Win10也同样适用本方法。
