根据 Appdata\Local 文件夹的日期删除用户配置文件
Delete user profiles based on the date of the Appdata\Local folder
感谢 Microsoft 打破了“在系统重新启动时删除早于指定天数的用户配置文件”GPO 并且这些年来都没有修复它，我需要一个脚本来删除旧的用户配置文件。问题是，我不需要它查找用户配置文件文件夹本身的修改日期，而是根据用户配置文件的 Appdata 文件夹中本地文件夹的修改日期删除用户配置文件。我注意到，即使您每天登录，用户个人资料文件夹的修改日期可能多年都不会改变，但本地文件夹似乎确实会根据您的登录时间而改变。
所以，我从用户 cxr-aus 制作的 spiceworks post 中抓取了这个。
$useraccounts = Get-ChildItem -path C:\users\ | Where-Object lastwritetime -lt (Get-Date).AddDays(90) | Select-Object Name
$sort = $useraccounts | ForEach-Object {$_.Name}
$removeaccounts = $sort -join "|"
Get-WmiObject -Class Win32_userprofile | Where-Object {($_.LocalPath -match "$removeaccounts") -and (!$_.special)} | Remove-WmiObject -whatif
您可以删除代码末尾的 -whatif 以使其删除用户配置文件。
我 运行 遇到的第一个问题是我需要这个来删除多个用户配置文件，因此 Remove-WmiObject 不起作用，因为 Get-WmiObject return 对我来说有多个配置文件，所以要修复它为了工作，我使用 % { $_.Delete()} 而不是像下面这样。
警告：请谨慎使用以下代码，因为 -whatif 不适用于它，它可能会开始从您的计算机上删除多个配置文件。
$useraccounts = Get-ChildItem -path C:\users\ | Where-Object {$_.lastwritetime -lt (Get-Date).AddDays(90)} | Select-Object Name
Foreach ( $user in $useraccounts) {
$sort = $useraccounts | ForEach-Object {$_.Name}
$removeaccounts = $sort -join "|"
$Username = $removeaccounts.name
Get-WmiObject -Class Win32_userprofile | Where-Object {($_.LocalPath -match "$Username") -and (!$_.special)} | % { $_.Delete()}}
您可以看到我确实更改了代码的其他一些方面以尝试将其分解，以便代码一次在一个配置文件上运行。这种方法有效，因为它将根据用户配置文件文件夹的修改日期开始删除文件夹
但问题是它会删除昨天可能已经使用过的用户配置文件，但是用户配置文件文件夹的修改日期没有改变。
所以我需要脚本做的是：
1.Get C:\users 目录中的所有用户配置文件文件夹
- 进入用户配置文件文件夹并获取 appdata\local 文件夹的修改日期。
3.Then return 只有 appdata\local 文件夹在这种情况下 90 天未被修改的用户配置文件文件夹。
我已经尝试了一些方法来改变这段似乎是死胡同的代码。有人可以帮我解决这个问题吗？
好的。
确保在生产中使用之前彻底测试它。
我添加了一些有用的注释来破译您在这段代码中尝试做的事情。

我首先将 $env:HomeDrive 更改为 $env:SystemDrive 因为我的环境设置不同。我还添加了一个 $ExcludeUsers，这样它就不会获取管理员或其他系统用户配置文件文件夹。由于您所做的更改，Remove-WmiObject 适用于 Users 文件夹中的多个配置文件，并且我能够通过 运行 此脚本一次删除 20 多个配置文件。出于某种原因，我想不通，-match 不再有效。它不会将 $account 视为完整的本地路径，因此我将其更改为 -contains，这对我来说似乎已经足够了。对于其他人，请务必在使用前彻底测试脚本。这是一个非常强大的脚本。
