It then outputs the count of certificates in each group and details about each certificate such as the common name (CN), expiration date, and number of days until expiration.
To use the script, simply open PowerShell and run it. The script will automatically retrieve all server authentication certificates installed on the local machine and group them by their expiration dates.
