Repacking the CAB File with Device Information

  1. Step 1: Extract the contents of the original .cab file, including the INF file.
  2. Step 2: Use a tool like CABArchive or WinCAB to pack the updated INF file into a new .cab archive. This will ensure that the device information is included in the archive and can be detected by the installer.

💡 Conclusion
