Version Mismatch: Using a CAB file from a different Windows build (e.g., trying to use a Windows 1809 file on a 22H2 system) can cause system instability or "Assembly not found" errors.

Corrupt Files: Unofficial mirrors often host incomplete files that fail during the DISM injection process.

Pro Tip: If you're a system administrator, you can also download these packages via the Volume Licensing Service Center (VLSC) or the Microsoft Evaluation Center as part of the "Languages and Optional Features" ISO.
