How to check windows certificate expiry date using PowerShell?
To get the particular windows certificate expiry date from the particular store, we first need the full path of that certificate along with a thumbprint. If the thumbprint is not known to you, we can use the friendly name.
With the thumbprint,
Get-ChildItem Cert:\LocalMachine\root\0563B8630D62D75 | fl *
When you run the above command, it will get all the details of the certificate having thumbprint 0563B8630D62D75.
