首先先要确定有没有下载office,没下载可以根据后续几步先行下载:

1.下载office tool plus:(主要是能够帮助用户一键部署、激活Microsoft Office) 打开必应搜索office tool plus: 目前网址：下载 | Office Tool Plus (landian.vip)

2.下载完成后先卸载一次office，之后按如下图选择（优先）安装：

也可以通过自带的windows（都行）

接下来是使用免费office资源了：

1. 打开https://massgrave.dev/get获取到对应的代码，之后通过终端（powershell）

当然资源可能出现打不开，代码如下：（复制到终端即可）

}

$writer.Write($response)
$writer.Flush()
$stream.Position = 0

    Write-Warning "Hash ($hash) mismatch, aborting!`nReport this issue at https://massgrave.dev/troubleshoot"
    $response = $null
    return
}

# Check for AutoRun registry which may create issues with CMD
$paths = "HKCU:\SOFTWARE\Microsoft\Command Processor", "HKLM:\SOFTWARE\Microsoft\Command Processor"
foreach ($path in $paths) { 
    if (Get-ItemProperty -Path $path -Name "Autorun" -ErrorAction SilentlyContinue) { 
        Write-Warning "Autorun registry found, CMD may crash! `nManually copy-paste the below command to fix...`nRemove-ItemProperty -Path '$path' -Name 'Autorun'"
    } 
}

$rand = [Guid]::NewGuid().Guid
$isAdmin = [bool]([Security.Principal.WindowsIdentity]::GetCurrent().Groups -match 'S-1-5-32-544')
$FilePath = if ($isAdmin) { "$env:SystemRoot\Temp\MAS_$rand.cmd" } else { "$env:TEMP\MAS_$rand.cmd" }

$ScriptArgs = "$args "
$prefix = "@::: $rand `r`n"
$content = $prefix + $response
Set-Content -Path $FilePath -Value $content

# Set ComSpec variable for current session in case its corrupt in the system
$env:ComSpec = "$env:SystemRoot\system32\cmd.exe"
Start-Process cmd.exe "/c """"$FilePath"" $ScriptArgs""" -Wait

$FilePaths = @("$env:TEMP\MAS*.cmd", "$env:SystemRoot\Temp\MAS*.cmd")
foreach ($FilePath in $FilePaths) { Get-Item $FilePath | Remove-Item }

2. 之后进入如下界面，选择2，然后选择1install资源即可：

3. 等待运行完成后，打开office即可完成认证：
