我正在运行 Windows Server 2016。在Dism /online /Get-Featurespower shell 上执行时，我得到以下输出：
Version: 10.0.14393.0
Image Version: 10.0.14393.2457
Error: 0x800f0805
The specified package is not valid Windows package.
我尝试运行Cleanup-Image和Restore-Health命令无数次，但无济于事。 dism.log 文件显示了以下可能相关的输出：

我不知道该怎么办。有没有办法“重置”这个 DISM？或者手动执行它无法自行执行的操作？
