win7通过wsus升级到win10总结

Posted 2020-11-22

在wsus服务器,打开IIS，选择“wsus”服务，点击 mime type,修改或者添加".esd"

Filename extension: .esd
Mime type: application/octet-stream

• windows server 2016 wsus IIS mime type：
  .esd的内容是“application/vnd.ms-cab-compressed”需要修改，否则会提示找不到资源
  
  

需要升级的客户端导入注册表，也可以使用GPMC下发组策略导入

对于win7 客户端，需要允许OSupdate,注册表如下:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade]
"Refresh"=dword:00000001
"AllowOSUpgrade"=dword:00000001

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgradeState]
"OSUpgradeState"=dword:00000001
"OSUpgradeStateTimeStamp"="2016-01-02 03:40:44"

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdate]
"WUServer"="http://172.20.156.34:8530"
"WUStatusServer"="http://172.20.156.34:8530"
"DisableOSUpgrade"=dword:00000000
"DeferUpgrade"=dword:00000000
"RequireDeferUpgrade"=dword:00000000

[HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdateAU]
"NoAutoUpdate"=dword:00000000
"AUOptions"=dword:00000004
"ScheduledInstallDay"=dword:00000000
"ScheduledInstallTime"=dword:00000001
"UseWUServer"=dword:00000001

• 配置成功后再windows update界面就可以看到升级提示，点击“开始安装”就会自动升级安装，此安装保留应用和个人资料。
  
• 通过WSUS从win7升级到win10,需要重新激活win10
• 可以通过部署kms激活或者组策略批处理安装win10密匙“slmgr /ipk 密匙”
