Dism 错误 0x800f0806

使用下面命令进行组件清理时出错：

dism /image:c:\ /cleanup-image /startcomponentcleanup /scratchdir:c:\ /logpath:z:\dism.log

failed to perform Synchronous Cleanup operation [HRESULT = 0x800f0806 - CBS_E_PENDING]
CBS Received notification that the operation is complete.
CBS Session: 1320_397531 finalized. Reboot required: yes
[HRESULT = 0x800f0806 - CBS_E_PENDING]

如果系统能正常启动，重启应该是可以的。
但是，由于不能正常启动，所以，这个过程无法完成。

那么，只要把 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing 下的挂起包和会话全部删除，再把 c:\windows\winsxs\pending.xml 删除，就可进行清理了。
