cygwin为什么无法找到Windows OpenSSH目录？

Question

所以我已经为Windows 10安装了OpenSSH，并在cygwin中删除了一个。我试图让cygwin改用Windows，但出现了一个奇怪的错误，即cygwin无法找到目录。我检查了权限，一切似乎还可以。

这是icacls所说的：

cygwin在这里抱怨：

{ ~ }  » ls -ld /cygdrive/c/Windows/System32
drwxr-xr-x 1 Steiny None 0 Feb 25 08:45 /cygdrive/c/Windows/System32
{ ~ }  » ls -ld /cygdrive/c/Windows/System32/OpenSSH
ls: cannot access /cygdrive/c/Windows/System32/OpenSSH: No such file or directory

cygwin为什么找不到C:\Windows\System32\OpenSSH目录？
