为什么HKCR \ pngfile上下文菜单在Windows XP中有效但在Windows 7中无效？

Question

我一直在尝试添加一个命令来处理我的Windows 7 64位上的PNG文件：

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.png\OpenWithProgids]
"pngfile"=""

[HKEY_CLASSES_ROOT\pngfile\shell\PNGProcess]
@="Process"

[HKEY_CLASSES_ROOT\pngfile\shell\PNGProcess\command]
@="\"C:\\Program Files (x86)\\PNGProcess\\pngproc.exe\" \"%1\""

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.png\UserChoice]
"Progid"="PBrush"

[HKEY_CURRENT_USER\Software\Classes\.png]
@="png_auto_file"

适用于Windows XP，但不适用于Windows 7 64位。

同样的注册表添加适用于该Windows 7 64位系统上的HKCR\jpegfile，但HKCR\pngfile不起作用。

我仔细检查以验证这些条目是否实际存在于注册表中的正确位置。他们做到了！

对此感到困惑，我检查了其他程序，将上下文菜单项添加到图形文件扩展名中，即使是古老的GIMP，这个问题确实存在！

我试图找到有关PNG和Windows 7的已知特性的信息，但找不到任何信息。

知道在Windows 7中pngfile有什么特别之处吗？

更新：根据以下建议，当我右键单击.png文件（访问上下文菜单）时，我捕获了相关操作，这会自动重新创建值png_auto_file：

Answer 1

这些密钥可能会失败的原因有多种，而且您几乎没有提供任何信息，因此这些是一般的故障排除提示

1. 您没有说，但您是否已将.png个文件与pngfile ProgID相关联？您可以检查HKCR\.png
的默认值
2. 是否为UserChoice文件分配了默认程序/ .png，这些文件会将ProgID更改为pngfile以外的其他内容？您可以通过查找HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.png\UserChoice并检查该ProgID
进行检查
3. 这个“PNGProcess”动词的HKCU版本是否指向不同的应用程序或者配置错误？在HKCU\Software\Classes\.png
中检查该密钥

问题修改后更新：

您的.reg文件中存在不一致之处。您正在将PNGProcess动词添加到pngfile ProgID，但是您将UserChoice设置为PBrush，然后您设置了默认.png ProgID到png_auto_file。这是三种不同的ProgID。他们需要都是一样的。
