07/04/2024

本文包含客户可以实现或用作模板的示例脚本，以了解如何创建自己的脚本。使用此处提供的信息为修正创建脚本包。

脚本说明

此表显示了脚本名称、说明、检测、修正和可配置的项目。名称以 Detect 开头的脚本文件是检测脚本。修正脚本以 Remediate 开始。可以从本文的下一节中复制这些脚本。

脚本名称	说明
检查网络证书 `Detect_Expired_Issuer_Certificates.ps1` `Remediate_Expired_Issuer_Certificates.ps1`	检测 CA 在计算机或用户的个人存储区中颁发的已过期或即将过期的证书。通过在检测脚本中更改的值来 `$strMatch` 指定 CA。将 `$expiringDays` 指定为 0 以查找过期证书，或指定另一个天数来查找即将过期的证书。通过向用户发出 Toast 通知来修正。 `$Title`使用希望用户看到的消息标题和文本指定和 `$msgText` 值。通知用户可能需要续订的过期证书。使用登录凭据运行脚本：是
清除过时的证书 `Detect_Expired_User_Certificates.ps1` `Remediate_Expired_User_Certificates.ps1`	检测由当前用户的个人存储区中的 CA 颁发的过期证书。通过在检测脚本中更改的值来 `$certCN` 指定 CA。通过从当前用户的个人存储中删除 CA 颁发的过期证书来修正。通过在修正脚本中更改的值来 `$certCN` 指定 CA。从当前用户的个人存储中查找和删除 CA 颁发的过期证书。使用登录凭据运行脚本：是
(内置) 更新过时的组策略 `Detect_stale_Group_Policies.ps1` `Remediate_stale_GroupPolicies.ps1`	检测上次组策略刷新是否已超过 `7 days` 之前。此脚本包包含在修正中，但如果想要更改阈值，则会提供一个副本。通过在检测脚本中更改 `$numDays` 的值来自定义七天阈值。通过运行 `gpupdate /target:computer /force` 和 `gpupdate /target:user /force` 在通过组策略传递证书和配置时，帮助减少与网络连接相关的支持调用。使用登录凭据运行脚本：是

检查网络证书脚本包

此脚本包检测计算机或用户的个人存储中 CA 颁发的已过期或即将过期的证书。脚本通过引发对用户的 toast 通知来进行修正。

清除过时的证书脚本包

此脚本包检测当前用户个人存储中 CA 颁发的过期证书。脚本通过从当前用户的个人存储中删除 CA 颁发的过期证书来进行修正。
