注册表改右键菜单和默认程序

文件夹中的右键菜单

在注册表编辑器中定位到：HKEY_CLASSES_ROOT\Directory\Background\shell，在其下新建项，

例如: 在目录C:\Users\CharleeChan\AppData\Local\Microsoft\Windows\WinX\Group3下，有10 - Programs and Features.lnk程序与功能,右键打开,找到其目标,该目标即为卸载程序的命令.
命令为:%windir%\system32\control.exe /name Microsoft.ProgramsAndFeatures

则相应的.reg文件为:

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\Background\shell\Programs And Features]
"Icon"="control.exe"
@="Unistall Programs"

[HKEY_CLASSES_ROOT\Directory\Background\shell\Programs And Features\command]
@="control.exe /name Microsoft.ProgramsAndFeatures"
