Office 预览版本启用界面UI，您可以尝试以下方案进行操作：
在桌面新建空白文本文档，复制输入以下内容：
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides]
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\access]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\excel]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\onenote]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\outlook]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\powerpoint]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\project]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\publisher]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\visio]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs\ExternalFeatureOverrides\word]
"Microsoft.Office.UXPlatform.FluentSVRefresh"="true"
"Microsoft.Office.UXPlatform.RibbonTouchOptimization"="true"
"Microsoft.Office.UXPlatform.FluentSVRibbonOptionsMenu"="true"
输入后保存，重命名为“Office新界面”，文件格式变更为“.reg”，完成后右键运行即可。
注：由于上述的方案涉及到注册表信息的修改，建议您在操作之前，先将注册表导出进行备份。
希望以上的信息可以帮助到您，如果存在疑问或其他问题，也欢迎随时回复本帖。
