哇、看都看不懂吖、这忙帮不了、呵

echo. 实际效果是 空行

SET Choice= ::设置变量Choice SET /P Choice=    Please Select Option[Enter 'C' or 'D']:  ::SET /P variable=[promptString]     /P 命令行开关允许将变量数值设成用户输入的一行输入。读取输入行之前，显示指定promptString

。promptString就是提示语句。     显示Please Select Option[Enter 'C' or 'D']:并把输入值赋给Choice ECHO.

IF NOT '%Choice%'=='' SET Choice=%Choice:~0,1% :: SET Choice=%Choice:~0,1% 提取 Choice 变量的所有字符，除了第一个。 IF /I '%Choice%'=='C' Goto BackupOffice

IF /I '%Choice%'=='D' Goto RestoreOffice

net stop osppsvc ::停止osppsvc服务，osppsvc是验证office激活状态的服务

takeown /f "%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat"

::takeown /f  指定文件名或目录名模式，指定了路径"%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat"并成为文件拥有者

cacls "%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat" /grant administrators:F /t

::cacls /grant 赋予指定用户administrators访问权限 /t 更改当前目录及其所有子目录中指定访问控制列表

del /F /Q "%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat"

copy "%~dp0tokens.dat" "%ALLUSERSPROFILE\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat"

takeown /f "%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\Cache" /ricacls "%ALLUSERSPROFILE%\Microsoft\OfficeSoftwareProtectionPlatform\Cache" /grant administrators:F /t

下面那一段命令被我肢解了，你应该能看懂了吧？
