Visual Studio 2013重置工作环境出现错误，大神们帮帮忙

您的设置已重置，但是有一些错误。
错误 1: 任务列表显示设置: 任务列表格式已更改。

尝试下命令行下执行呢？
/ResetUserData - (AFAICT) Removes all user settings and makes you set them again. This will get you the initial prompt for settings again, clear your recent project history, etc.
/ResetSettings - Restores the IDE's default settings, optionally resets to the specified VSSettings file.
/ResetSkipPkgs - Clears all SkipLoading tags added to VSPackages.
/ResetAddin - Removes commands and command UI associated with the specified Add-in.
