###################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 #
##################################################################################################################

#指定VHD文件存放位置
$VHD_File = "e:\vhd\test\win2008r2.vhdx"
#指定补丁文件存放位置
$Updates_Folder = "E:\vhd\Kb"
#指定VHD挂载后的OS分区盘符

#DISM命令日志存放于当前脚本目录下
$CurrentPath = $MyInvocation.MyCommand.Path.substring(0,$MyInvocation.MyCommand.Path.LastIndexOf('\')+1)
#$today = Get-Date -UFormat "%Y%m%d"
#如果将dism过程输出到Log，则当前屏幕无显示
#$DISM_Log = $CurrentPath+"Dism_$today.txt"

#使用Diskpart命令挂载VHD ，并指定盘符（注：该VHD必须包含系统保留分区，否则所选择的分区会不正确，需要使用 partition 1）
