Q:

微软偷偷摸摸给Firefox安装了"Windows Presentation Foundation 3.5.30729.1"，
现在只能禁用，无法卸载，怎么办？

A:

1) 关闭Firefox

2) 重命名或删除如下目录中的所有子目录、普通文件:

%SystemRoot%\Microsoft.NET\Framework\v3.5\Windows Presentation Foundation\

一般有两项:

DotNetAssistantExtension\
NPWPF.dll

3)

备份并删除如下注册表子键:

HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@microsoft.com/WPF,version=3.5

下面是我备份的原有内容:

--------------------------------------------------------------------------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@microsoft.com/WPF,version=3.5]
"Description"="Windows Presentation Foundation plug-in for Mozilla browsers"
"GeckoVersion"="1.7.2"
"Path"="C:\\WINDOWS\\Microsoft.NET\\Framework\\v3.5\\Windows Presentation Foundation\\NPWPF.dll"
"ProductName"="Windows Presentation Foundation"
"Vendor"="Microsoft Corp."
"Version"="3.5"

[HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@microsoft.com/WPF,version=3.5\MimeTypes]

[HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins\@microsoft.com/WPF,version=3.5\Suffixes]
"xbap"=""
"xaml"=""

4) 重启Firefox
