  .esd的內容是“application/vnd.ms-cab-compressed”需要修改，否則會提示找不到資源
  
  

需要升級的客戶端導入注冊表，也可以使用GPMC下發組策略導入

對于win7 客戶端，需要允許OSupdate,注冊表如下:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade]
"Refresh"=dword:00000001
"AllowOSUpgrade"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\State]
"OSUpgradeState"=dword:00000001
"OSUpgradeStateTimeStamp"="2016-01-02 03:40:44"

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
