###################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Mount-VHD命令挂载VHD文件，该命令包含在Windows Server 2012中，挂载后的盘符无法确定，需要手工指定，如“U:\”#
#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 #
##################################################################################################################

$VHD_File = "e:\vhd\test\win2008r2.vhdx"
$Updates_Folder = "E:\vhd\Kb"
#指定盘符
$letter = "U:\"

#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)
#$today = Get-Date -UFormat "%Y%m%d"
#$DISM_Log = $CurrentPath+"Result_$today.txt"

#生成添加补丁更新的DISM命令
Function Add_Updates ($Updates_Folder)
{
$Updates = gci $Updates_Folder |? {$_.Extension -eq ".msu" -or $_.Extension -eq ".cab"} |Select Fullname
Foreach ($Update in $Updates)
{
$DISMcmd += "dism /Image:" + $letter + " /Add-Package /PackagePath:" + $Update.Fullname + " /IgnoreCheck" + "`n"
}
Return $DISMcmd
}
