win7批量删除系统更新补丁
1、在e盘，新建记事本，把以下代码复制其中，然后保存为文件名为a.ps1。
$KBID = "KB958488"
$KBID1 = "KB976902"
cls
function Remove-Update {
$HotFixes = Get-HotFix
[int]$count = 0;
foreach ($HotFix in $HotFixes)
{
$count = $count + 1
Write-Host $count / $HotFixes.Count
if (($KBID -ne $HotFix.HotfixId) -and ($KBID1 -ne $HotFix.HotfixId))
{
"Inside first if"
$KBID = $HotFix.HotfixId.Replace("KB", "")
$RemovalCommand = "wusa.exe /uninstall /kb:$KBID /quiet /norestart"
Write-Host "Removing $KBID from the target."
Invoke-Expression $RemovalCommand
}
if ($KBID -match "All")
{
$KBNumber = $HotFix.HotfixId.Replace("KB", "")
$RemovalCommand = "wusa.exe /uninstall /kb:$KBNumber /quiet /norestart"
Write-Host "Removing update $KBNumber from the target."
Invoke-Expression $RemovalCommand
}
if ($KBID -match "Security")
{
if ($HotFix.Description -match "Security")
{
$KBSecurity = $HotFix.HotfixId.Replace("KB", "")
$RemovalCommand = "wusa.exe /uninstall /kb:$KBSecurity /quiet /norestart"
Write-Host "Removing Security Update $KBSecurity from the target."
Invoke-Expression $RemovalCommand
}
}
while (@(Get-Process wusa -ErrorAction SilentlyContinue).Count -ne 0)
{
Start-Sleep 3
Write-Host "Waiting for update removal to finish ..."
}
}
}
Remove-Update
2、点开开始-找到搜索-输入cmd-右键选择管理员打开。
3、输入PowerShell ，然后回车。
4、输入Set-ExecutionPolicy RemoteSigned ，然后回车。
5、输入E:a.ps1，然后回车。
6、以上代码的核心思想：windows 的"wusa.exe"和ps1批处理文件，全部步骤操作完，最后重启电脑即可，因为补丁的配置，所以关机和开机都要挺久的。请不要断电，直到电脑回到系统桌面。
