However, the generic PCI bridge driver is still served via the "Microsoft Update Catalog" as part of security rollups.

If you want the pure Microsoft driver:

1. Open Windows Update → Check for updates.
2. Look under "Optional updates" → "System Devices".
3. You may see "PCI Express Root Port" updates – these often cover the ASMedia bridge.
