方法一：

1.在桌面新建一个文本文档，

2.然后直接复制以下代码粘贴到txt文档中：

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{31C0DD25-9439-4F12-BF41-7FF4EDA38722}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{31C0DD25-9439-4F12-BF41-7FF4EDA38722}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{35286a68-3c57-41a1-bbb1-0eae73d76c95}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{35286a68-3c57-41a1-bbb1-0eae73d76c95}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{f42ee2d3-909f-4907-8871-4c22fc0bf756}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{f42ee2d3-909f-4907-8871-4c22fc0bf756}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{7d83ee9b-2244-4e70-b1f5-5393042af1e4}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{7d83ee9b-2244-4e70-b1f5-5393042af1e4}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{0ddd015d-b06c-45d5-8c4c-f59713854639}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{0ddd015d-b06c-45d5-8c4c-f59713854639}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{a0c69a99-21c8-4671-8703-7934162fcf1d}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{a0c69a99-21c8-4671-8703-7934162fcf1d}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{B4BFCC3A-DB2C-424C-B029-7FE99A87C641}\PropertyBag]
"ThisPCPolicy"="Hide"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{B4BFCC3A-DB2C-424C-B029-7FE99A87C641}\PropertyBag]
"ThisPCPolicy"="Hide"

3.保存后改为reg格式（或点击文件->另存为，保存类型选择所有文件，文件名为“XXX.reg”），双击运行，隐藏3d对象 需要之后在 任务管理器 中找到Windows资源管理器，右键重启即可。

4.此方法适用于1909版本的WIN10。

方法二：

通过 WIN+R 键，输入 regedit 后确认，打开注册表。定位到

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions

中，分别找到代表这些文件夹的项，然后将其子项 PropertyBag 中的 ThisPCPolicy 键的值由 Show 改为 Hide 即可。如不存在 PropertyBag项，右键新建子项； 如不存在 ThisPCPolicy 键，右键新建字符串值(S) 再赋值。

3d对象需要之后通过任务管理器重启Windows资源管理器。

如需重新显示，把Hide改为Show即可。方法二同理。

方法三：（推荐）

直接复制以下代码到txt文档中另存为reg文件双击导入到注册表：
