Code 7

The drivers for this device need to be reinstalled

What it means

Windows found a driver registration but the files or settings behind it are missing, so the device cannot start.

Common causes

• A driver uninstalled incompletely
• A restored system image with missing files
• A failed driver update

How to fix it

1. Uninstall the device and tick "Attempt to remove the driver for this device" if offered.
2. Restart, then install the current driver from the maker.
3. Run sfc /scannow if the device is built into the PC.
4. Check Windows Update's optional driver updates as a fallback.
