电脑系统重做后搜不到wifi,电脑系统重做后excel

1、如果word文件 ，excel文件，幻灯片文件在系统盘，重装的系统时系统盘将被GHOST格式化，你的文件也就没有了。

2、如果word文件 ，excel文件，幻灯片文件在其它盘，需要并且安装系统软件时捆绑安装了Microsoft office软件，那么需要人工寻找到你的word文件 ，excel文件，幻灯片文件，并且双击打开文件即可。

3、如果你原来安装的Microsoft office软件版本较高，如2007、2010等而重新安装的Microsoft office软件版本较低（一般系统捆绑2003），可以寻找安装补丁后打开你的文件。

4、如果不喜欢低版本就只好下载Microsoft office2007、Microsoft office2010了，并且安装。

5、如果对于安装电脑软件不熟悉，可以在百度搜索“怎样安装Microsoft office软件”，“那个Microsoft office软件好”，帮助你进行安装。

6、可以把邮箱发给我，我给你发Microsoft office软件。

解决方案：

打开excel，依次选择：工具----选项------常规-设置-----“忽略其他应用程序”的勾去掉。

初步估计是病毒把excel文件的“打开”设置更改了。

如果还不行，可以尝试将下列红字部分复制到记事本内，保存为excel.reg，然后双击添加到注册表。然后再按上述步骤操作。
