今天去“打开和关闭 Windows 功能”设置中打开 Hyper-V 功能，但对话框总是只加载 20 秒左右，然后导致我的机器崩溃。
我查找了查看/访问 Windows 功能的其他方法，发现可以通过 DISM 或 Powershell 进行操作。我尝试使用两个命令来查看 Windows 功能：
dism /online /get-features
和
get-windowsoptionalfeature -online
在这两种情况下我都会得到这个错误：
Error: 582
An illegal character was encountered. For a multi-byte character set this
includes a lead byte without a succeeding trail byte. For the Unicode character
set this includes the characters 0xFFFF and 0xFFFE.
查看 dism 日志和 CBS 日志后：

显然，这些命令尝试读取的任何地方都有一些损坏的值。我只是不确定那是注册表值还是其他东西，我不知道如何在不完全重新映像我的机器的情况下修复此问题。
任何帮助表示感谢
