Question 2

这可能是因为文件在正在运行的程序中打开。您可以尝试使用 Windows 中的磁盘清理实用程序来清理 Temp 文件夹。如果在线时不起作用，请尝试启动到安全模式并从那里删除它们。

Question 3

我发现停止以下代码中的三个服务很有帮助。我最初用另一种语言编写了帮助文本，翻译起来很麻烦，但我添加了我为技术水平较低/不懂命令行的同事编写的相关 PowerShell 代码，以便从记事本/其他东西粘贴到 powershell.exe 中，并逐步运行，以半自动清理失控 cab 文件生成的计算机。我正在翻译我现在发现的最相关的部分。

当 CBSPersist 日志大小达到 1 或 2 GB 左右（我忘了是哪个，认为是后者）时，可能会发生这种情况，并且 makecab.exe 会尝试压缩它，失败，并且不会自行清理，并无限期地重复此操作。

我们通过使用 sysinternals 进程监视器来监视服务器，发现了这个问题。如果我没记错的话，这似乎是由 Windows 更新触发的。

这是代码，希望它能对某人有所帮助。

# Ensure we have a C:\temp. No output (necessary, but if you know what you're doing, you can tweak ... )
$TempDir = 'C:\temp'
if (-not (Test-Path -Path $TempDir -PathType Container)) { New-Item -ItemType Directory -Path $TempDir | Out-Null }
Set-Location -Path $TempDir

# Stop services. Lim inn disse tre linjene i powershell.exe og vent til den er ferdig.
# it could take a couple of minutes 
Stop-Service -Name TrustedInstaller
Stop-Service -Name wuauserv
Stop-Service -Name BITS


# Wait for makecab.exe to stop working, it seems to die by itself after 
# about a minute or three for me once you stop the services
# if you want something to look at while waiting for makecab.exe to die.
# you can also just look in task manager ...
$ProcessToCheck = 'makecab'
if (@(Get-Process -Name $ProcessToCheck -ErrorAction SilentlyContinue).Count -gt 0) {
    while (@(Get-Process -Name $ProcessToCheck -ErrorAction SilentlyContinue).Count -gt 0) {
        Write-Host -ForegroundColor Yellow "Waiting for ${ProcessToCheck}.exe to die ..."
        Start-Sleep 10
    }
}
else {
    Write-Host -ForegroundColor Green "${ProcessToCheck}.exe is not running at all (anymore)."
}
Write-Host -ForegroundColor Green "${ProcessToCheck}.exe died, so you can continue."

# Så skal vi slette cab_*_*-filene fra C:\Windows\Temp og vi er paranoide så vi vil se over
# filene først for å verifisere. Kan hoppes over hvis du er verdensvant og sikker, antar jeg.
# Lim inn alle disse linjene under i powershell.exe-vinduet og trykk enter (blank linje) til slutt.
# Eller marker i PowerShell ISE og trykk F8.
