我看到了有效日期等信息，但我正在寻找证书实际安装的日期。
答案1
证书存储在注册表中的以下两个位置，最终密钥值与证书指纹相同。因此，只要您有指纹值，您就可以查询正确的注册表密钥
[HKLM\SOFTWARE\Microsoft\SystemCertificates\]
[HKCU\Software\Microsoft\SystemCertificates\]
使用此处的 PowerShell 函数获取 RegistryKeyLastWriteTime您可以查询注册表项以了解上次写入时间。
如果链接失效，以下 PowerShell 函数的完整代码（这不是我的工作）
Function Get-RegistryKeyTimestamp {
<#
.SYNOPSIS
Retrieves the registry key timestamp from a local or remote system.
.DESCRIPTION
Retrieves the registry key timestamp from a local or remote system.
.PARAMETER RegistryKey
Registry key object that can be passed into function.
.PARAMETER SubKey
The subkey path to view timestamp.
.PARAMETER RegistryHive
The registry hive that you will connect to.
Accepted Values:
ClassesRoot
CurrentUser
LocalMachine
Users
PerformanceData
CurrentConfig
DynData

您应该能够在 Windows 中搜索应用程序事件日志以找到证书，但是如果您的事件日志已溢出并且您没有打开日志轮换/存档，则该数据可能会永远丢失。
只需搜索确切的友好名称字符串或指纹（不带空格），例如以下内容出现在我的事件日志注释中：
Successful auto update of third-party root certificate:: Subject: <CN=QuoVadis Root CA 2, O=QuoVadis Limited, C=BM> Sha1 thumbprint: <CA3AFBCF1240364B44B216208880483919937CF7>.
对于此证书：
