使用wusa.exe卸载更新

Question

我想写一个卸载更新的powershell脚本。

我的问题是脚本在启动脚本时不运行wusa.exe。

function Uninstall-Hotfix() { 
    [string]$parameters = "KB4041691" 
    [string]$KBs = @() 

    if ($parameters.Contains(":")) { 
     [object]$arguments = $parameters.Split(":") 
     foreach ($argument in $arguments) { 
      $argument.Replace("KB", "") 
      $KBs.add($argument) 

      for ($i = 0; $i -lt $KBs.length; $i++) { 
       Cmd /c wusa.exe /uninstall /KB:$KBs[$i] /quiet /norestart 
       Do { 
        Start-Sleep -Seconds 3 
       } 
       while (Wait-Process | Where-Object {$_.name -eq "wusa"}) 

       If (Get-Hotfix -Id $KBs[$i] -ErrorAction SilentlyContinue) { 
        Write-Host "KB $KBs[$i] Fehlerhaft" 
       } 
       Else { 
        Write-Host "KB $KBs[$i] Erfolgreich deinstalliert" 
       } 
      } 
     } 
    } 
    Else { 
     $parameter = $parameters.Replace("KB", "") 
     $parameter 
     cmd /c wusa.exe /uninstall /KB:$parameter /quiet /norestart 
     Do { 
      Start-Sleep -Seconds 3 
     } 
     while (Wait-Process | Where-Object {$_.name -eq "wusa.exe"}) 
    } 
}

你的代码是非常沉重的，在我看来包含了太多的循环，你可以试试这个：

function Uninstall-Hotfix() { 
    Param(
     [Parameter(Mandatory=$true)][array]$Patches 
    ) 

    foreach($patch in $Patches){ 
     $numKb = $null 
     if($patch -match "\d{7}"){ 
      [int]$numkb = $Matches[0] 
      Write-Host $numKb 

      Start-Process wusa.exe -ArgumentList "/KB:$numKb /uninstall /quiet /norestart" -Wait 

      if(Get-Hotfix -Id $numKb -ErrorAction SilentlyContinue){ 
       Write-Host "KB $KBs[$i] Fehlerhaft" 
      } 
      else{ 
       Write-Host "KB $KBs[$i] Erfolgreich deinstalliert" 
      } 
     } 
     else{ 
      Write-Host "KB is not valid" 
     } 
    } 
}
