Question: Hey Doctor Scripto! Is there an easy way to visually identify Digitally signed files with an Expired status on the Digital Certificate?

Answer: Absolutely! We just need to filter on the “Status” property and show those without the value ‘Valid’. As an added bonus it would also identify files that are not digitally signed.

Get-Childitem C:\Folder\*.* -Recurse | Get-AuthenticodeSignature | Where-Object { $_.Status -ne ‘Valid’ }
