Manage - Windows Installer Cache

Overview​

The script performs a quarantine operation with force parameter to identify and isolate orphaned Windows Installer cache files, generates a manifest of the quarantined items, and then executes a deletion operation using the generated manifest. This staged approach provides a controlled and auditable remediation process while minimizing risk.

The implementation is designed for automated deployment, supports secure content delivery through code-signature validation, and helps reclaim disk space by safely removing orphaned Windows Installer cache files.
