Windows 8.1 x64 – Removing the Folders from File Explorer
2014-03-26习惯了打开资源管理器就是磁盘。win8.1提供的文件夹用的次数很少，一直想删掉，今天特意查了一下，原来可以修改注册表删掉的。
Win+R--regedit--enter.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\
{1CF1260C-4DD0-4ebb-811F-33C572699FDE} - Music Folder
{374DE290-123F-4565-9164-39C4925E467B} - Downloads Folder
{3ADD1653-EB32-4cb0-BBD7-DFA0ABB5ACCA} - Pictures Folder
{A0953C92-50DC-43bf-BE83-3742FED03C9C} - Videos Folder
{A8CDFF1C-4878-43be-B5FD-F8091C1C60D0} - Documents Folder
{B4BFCC3A-DB2C-424C-B029-7FE99A87C641} - Desktop Folder
Deleting all of these GUIDs from the NameSpace folder will remove these folders from Windows File Explorer:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\
