避免冲突!如何彻底卸载旧版本Office?
安装新版本Office软件之前,为了避免出现冲突,微软会建议用户卸载本机中所有的旧版本Office,但很多朋友发现有时使用常规的方法无法完全卸载它。下面我们就针对不同的场景,介绍几个彻底卸载旧版本Office的方法。
方法1:使用Microsoft SaRa工具
适合:正常安装的Office
如果使用Windows自带的“卸载或更改程序”卸载Office时遇到问题,给出错误代码,那么就要用到“Microsoft支持和恢复助手”(Microsoft Support and Recovery Assistant,以下简称为SaRa)这个专门用于诊断和修复Microsoft Office套件错误的工具了。
先到“https://aka.ms/SaRA-FirstScreen”下载SaRa,启动程序后点击“办公室”,在打开的新窗口中勾选遇到的问题,这里选择“我已安装了Office,但在卸载时遇到问题”。然后点击“下一步”,这时就会开始检测本机安装的Office,其余操作按屏幕提示进行即可完成卸载。
SaRa还提供命令行操作方式,可以帮好友自动卸载Office 365、Office 2021/2019/2016/2013/2010等。到“https://aka.ms/SaRA_CommandLineVersionFiles”下载所需的软件,将其解压到“D:\cfan”。然后启动记事本程序并输入以下代码,将其保存为“cfan.bat”,同样放置在“D:\cfan”下。
taskkill /f /im teams.exe
d:\cfan\SaRAcmd.exe -S OfficeScrubScenario –AcceptEula -Officeversion All
接下来压缩“D:\cfan”文件夹并传输给好友,好友将此文件夹解压到“D:\”,然后运行其中的“cfan.bat”就可以自动卸载Office了。
方法2:使用“Office部署工具”
适合:卸载C2R版本的Office 2019、2021或Office 365
如果本机中的Office是通过“Office部署工具”安装的,那么卸载时也要借助于它。到“https://www.microsoft.com/en-us/download/details.aspx?id=49117”下载该工具,将其解压到“D:\office”备用。
然后使用写字板程序打开“D:\office”下对应版本Office的配置文件,比如想卸载Office 2019,那就打开“configuration-Office2019Enterprise.xml”文件,将文末的“<Configuration>”和“</Configuration>”之间的代码按下图所示更改。保存后运行“D:\office\setup.exe”,就可以完成卸载了。
Office部署工具本身也存在卸载问题,通过“卸载或更改程序”卸载它后,如果需要安装其他套件,系统可能会提示“Office部署工具”已安装,导致套件安装失败。此时可以进入注册表编辑器,按下“Ctrl+F”快捷键,搜索关键词“Support and Recovery Assistant”,将找到的所有项都删除并重启,然后就可以正常安装其他套件了。
方法3:使用PowerShell
适合:Windows 10/11预装的Microsoft.Office.Desktop.Apps、Microsoft Store UWP
如果旧版本Office是Windows预装的,就需要通过PowerShell命令行来卸载。以管理员身份启动PowerShell,输入“Get-AppxProvisionedPackage -online | %{if ($_.packagename -match "Microsoft.Office.Desktop") {$_ | Remove-AppxProvisionedPackage -AllUsers}}”命令,回车后就可以完成卸载了。

控制台命令是智能主板维修必须掌握的知识点,也是必备利器,掌握这个知识点可以让你的维修过程事半功倍。
控制台分BootLoader控制台和安卓控制台,这个概念一定要分清楚,BootLoader控制台下可以执行擦空、强制升级、DDR自检、存储容量查询、串口打开关闭等。
安卓控制台下最常用的就是屏参修改,这也是换屏的维修师傅比较喜欢的知识,因为换屏时,很多时候都没有一模一样的原装型号屏,基本通过代换完成,代换后由于屏厂家和参数可能不一样,出现花屏、倒屏、灰屏等。都会做后期调试,比如改逻辑板,边条等,当然也有很多是改硬件不能完成的,掌握安卓控制台改屏参,就会有更多代换可能性。
也有一部分是自己误调试引起灰屏,或者换板时内置屏参本身不匹配引起的灰屏都会用到这个知识点,在一文中对MSD6A818芯片方案做了一个介绍,大家应该有一些共鸣。
我们先来看看几大芯片厂家控制台进入方法:
下面我们先聊聊BootLoader控制台下的几个方案常用命令。
一、Mstar
1、擦空 ,在Mstar方案里,有三种组合,Nor+Nand,Nor+EMMC,单EMMC,针对Nand和EMMC的擦除命令有点区别,但是擦空的时候一定要注意,工厂提供的U盘升级软件是不是支持空片烧录,如果不支持,那么你就好好的哭一场吧,擦空后你会发现再也不能升级了,或者怎么升级也生不好,不过对有RT809H的维修工程师来说,这不是什么大事,只要擦除之前对Nand或EMMC做一个5%左右的备份就可以了,擦除后再写入5%。
当然对拥有RT809H的用户都会会心一笑,可以用编程器直接擦呀,而且编程器自带擦空功能可以对一部分EMMC有修复功能。
Nor+Nand:nand erase;nand scrub。
Nor+EMMC:mmc erase。
单EMMC:mmc erase。
2、升级, 升级是我们比较常用的一个命令,在Mstar方案中,不同的组合结构,不同的升级文件名,升级命令都不一样,例如6i48的命令有
usb reset
ustar
这个命令是针对U盘升级文件为nand、script两个文件夹的,并不是所有MSD6i48都一样,同时U盘升级文件要支持空片烧录,不然只有用网线升级。
控制台下显示命令行格式为下图。
上图就是输入usb reset后没识别到U盘的一段打印,不同的主板设计的U盘升级口不一样,这个要注意,这时候就要检查U盘是否插入升级口,U盘是否正常被识别。
上图为正常识别到U盘的打印信息,这时候才能继续输入升级命令。
输入升级命令ustar后回车,升级软件正常就会监控到升级打印进度。
上图是早期的网络电视机主板升级命令,再例如早期的智能机MSD6A801芯片方案,用第一批乐视S40/S50举例,升级文件名为bin格式,
升级命令为uup或者usb_check_bin都可以。
后期的MSD6A628和MAD6A918开始一直到现在,升级文件名均为bin格式,升级命令为更简单的"cu",一定要小写。
在升级过程中,可以看到打印信息提示所需文件名(如下图),如果文件名错误是升级不成功的,所以遇到升级不成功需要检查U盘内的文件名是否与打印信息提示文件名相符。
3、打开串口,在我们维修Mstar方案的主板时,经常会看到串口关闭的打印,这种串口关闭的打印比较明显的标志就是 UART BUS OFF!! 串口关闭很是令维修人员头疼,因为它被关闭后,将看不到所有的打印细节,也就看 不到引导是否运行完整,主程序是否加载正常。
如果想看到这些细节来分析故障点,那么就要串口必须打开,串口关闭分两种情况,一种是能进控制台,一种是不能进控制台。能进控制台的只需要输入串口打开命令就可以了,下面我们以TCL MS828板举例。

后面太长,省略掉,现在是不是就可以看到很详细的打印了?有朋友问如果不能进入控制台该怎么办呢?不用担心,RT809H早已准备好不能进入命令行的串口打开方法。
在主界面芯片印字框输入EMMC,下方分类框选EMMC_ISP_MST_UART_ON这一项,飞线连接后直接点左侧写入,就会直接打开串口,查看到详细打印,操作简单直接。
下节精彩继续!
