打开电脑发现电脑管家提示有10G的垃圾 ，就清理了一下垃圾。清完垃圾之后发现电脑的文件夹和此电脑无法打开了。

文章参考来源：Win10打开资源管理器报错“explorer.exe 该文件没有与之关联的应用来执行该操作”的解决办法

注意：

1、修改注册表一定要做好备份，万分小心，否则可能出现更多问题导致系统无法使用。

2、以上只验证了Win10系统，Win11是否可用不清楚

操作方法：

Win + R 打开运行面板，输入 regedit，打开注册表编辑器

定位到路径：

计算机\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Discardable\PostSetup\ShellNew

双击Classes，如果是Folder消失了，可尝试添加看是否生效，不行继续往下看：

我的电脑是直接存在的，但是文件就是打不开，我选择用下面的方法解决的：

1、在桌面空白处，右键点击新建记事本；若没有直接在应用商店中下载记事本

2、在新创建的.txt文件中复制下方内容粘贴，保存文本文件并重命名为 "repair.reg"，右键，点击合并或者以管理员身份运行
