打开office提示还有几天过期的处理办法

是多重激活了，把激活码失效的删除即可

1、以管理员权限打开cmd（必须以管理员权限，不然无法删除无效的激活码）

2、输入命令：cd C:\Program Files (x86)\Microsoft Office\Office16
（目录的路径根据实际安装情况输入）
命令说明：切换到C:\Program Files (x86)\Microsoft Office\Office16此目录
面板会显示如下说明切换目录成功：
C:\WINDOWS\system32>cd C:\Program Files (x86)\Microsoft Office\Office16

3、再输入命令：cscript OSPP.VBS /dstatus

命令说明：查看office激活信息
面板会显示如下（隐藏部分用问号代替）【命令提示符中可以进行复制粘贴操作】
Microsoft (R) Windows Script Host Version 5.812
