Last content review: October 2026 — download links and steps re-checked against the official ASUS support page.
Looking for ASUS K451LB drivers? This guide shows exactly which drivers the ASUS K451LB needs on Windows 10 (64-bit) and Windows 8.1 (64-bit), in the correct install order, plus fixes for the most common problems after a clean install — no Wi-Fi, no sound, dead touchpad gestures, or missing function keys.
