| Do’s | Don’ts | |------|--------| | ✅ Create a system restore point before any driver change. | ❌ Never use "Driver Booster" or "Driver Easy" free versions (they bundle adware). | | ✅ Download drivers directly from Intel, Realtek, or Synaptics. | ❌ Don’t install every driver Windows Update offers (hide the touchpad and audio drivers). | | ✅ Keep a USB stick with all critical drivers (Wi-Fi, chipset, graphics). | ❌ Avoid .exe files from unknown forum attachments. | | ✅ Run the Intel Driver & Support Assistant monthly. | ❌ Don’t update a working driver unnecessarily. "If it ain’t broke, don’t fix it." |
