Changelog

All notable changes to Universal Intel Wi-Fi and Bluetooth Drivers Updater are documented here.

🚀 Release: v2026.03.0003

🆕 What's New

• Microsoft WHCP Digital Signature Verification

  • All downloaded CAB driver packages are now verified against the Microsoft Windows Hardware Compatibility Publisher certificate before installation
  • Verification runs after SHA-256 hash check and before expand.exe — identical security architecture to Universal Intel Chipset Device Updater
  • Installation is aborted if the signature is missing, invalid, or not issued by Microsoft WHCP

• Legacy Device Support

  • Database files (intel-bt-driver-latest.md, intel-wifi-driver-latest.md) now support optional per-device Latest Version and Release Date columns
  • A dedicated ## Legacy Devices section tracks EOL devices with their last available driver version
  • First legacy entry: Intel AX200 Bluetooth (PID_0029) — last supported version 24.10.0.4 (11/10/2025), Wi-Fi for AX200 remains fully supported
  • Script automatically displays [LEGACY] indicator for affected devices and installs the correct last-available CAB

💡 When Intel drops support for a device in a future driver release, simply move its entry to ## Legacy Devices in the .md file and add a dedicated block in the download .txt file — no script update required.

• Per-DEV Wi-Fi Download Blocks

  • intel-wifi-drivers-download.txt rebuilt to support per-device CAB blocks (mirrors existing BT parser structure)
  • Each block maps one or more DEV_XXXX identifiers to its own SHA256, Link, Backup, and optional Version/Date
  • A global header block ensures full backward compatibility with v2026.03.0002
  • Legacy Wi-Fi devices can now receive dedicated CAB packages independently from active devices

• Expanded Wi-Fi Hardware Coverage

  • Added 5 previously missing adapter DEV IDs to detection: AX203 (2030), AX101 (1010), Wireless-AC 9260 (9260), Wireless-AC 9461 (9461), Wireless-AC 9462 (31DC)
  • All newly added adapters are covered by the existing driver package — no new downloads required

• Installation Reliability

  • pnputil /add-driver exit code 259 (driver already staged) now correctly treated as success — required for force reinstall scenarios
  • pnputil /update-device exit codes 1 (device already on best driver) and 259 now correctly treated as success
  • Exit code 3010 (success, reboot required) was already handled — verified correct in all paths

• Code Quality

  • $isSFX detection pattern corrected to match actual script filename
  • .ICONURI populated in PSScriptInfo — PowerShell Gallery listing now displays the project icon
