Symptoms

  • Yellow triangle warning icon on a device in Device Manager
  • Error message specifically references Code 28
  • The device (printer, webcam, sound card, etc.) doesn't function
  • May follow a Windows update, reinstall, or connecting new hardware

Likely causes

  • CommonDriver never installed for that specific hardwareThis happens often after a fresh Windows install or a major update that doesn't include the needed driver.
  • CommonDriver files corrupted or incompletely installedA partial or interrupted driver installation leaves the device in this state.
  • PossibleOutdated driver incompatible with the current Windows versionAn older driver may not register correctly after a Windows feature update.
  • PossibleWindows Update removed a driver during an upgradeFeature updates sometimes strip drivers it considers outdated or incompatible.
  • Less commonHardware conflict with another deviceIn rare cases, a resource conflict can prevent proper driver installation.

What to do

  1. Right-click the device in Device Manager and choose 'Update driver,' then 'Search automatically for drivers' to let Windows try to find one.
  2. If that doesn't work, identify the exact make and model of the device and download the correct driver directly from the manufacturer's website.
  3. Uninstall the device entirely (right-click > Uninstall device), then restart the PC, which often prompts Windows to reinstall a working driver automatically.
  4. If a specific driver file was downloaded, run its installer directly rather than pointing Device Manager at loose files, since manufacturer installers often set up more than just the driver.
  5. Check Windows Update > Optional updates (Settings > Windows Update > Advanced options > Optional updates) for a driver update specific to that device.
  6. If the device is older and no modern driver exists, check whether a compatibility mode installation or an alternate generic driver is available.
  7. If the device still shows Code 28 after trying an official driver, it may indicate a hardware fault rather than purely a software issue.

Tools and parts

  • Another device to download drivers if needed

When to call a pro

If no official driver resolves Code 28 and the device still doesn't work, a technician can determine whether it's a deeper compatibility issue or the device itself has failed.
