Q4: Why does it say "new" in your keyword? Does the CAB expire?

No, the CAB file doesn't expire. But a "new" CAB refers to a freshly downloaded copy from a verified Microsoft ISO, rather than a years-old copy that might have been corrupted on your backup drive. Always re-download from a trusted source if you see checksum mismatches. Technical Overview: Installing
