VHD_Update_diskpart

###################功能说明#####################
###该脚本用来对离线VHD文件更新，导入系统补丁####
################################################

#####################################################实现过程#####################################################
#1.使用Diskpart命令挂载VHD文件，该VHD必须包含系统保留分区，OS默认所在第二个分区 #
#2.使用DISM命令将补丁更新（.cab、.msu）导入到VHD文件中，并将日志输出到当前目录下 #
#3.卸载VHD文件 #

 补丁更新完成后，如果某些补丁并未提示“不适用”，显示已成功，也有可能是真的不适用该系统，无法安装成功，如下图中的KB975560和KB2425227两个补丁在更新完成后系统中并未找到，直接安装这两个补丁，提示不适用。
