How to Fix Cannot Update Driver

Quick Answer

The Cannot Update Driver error usually means Windows blocked an unsigned driver, the install file is corrupt, or another process is holding the device. Fix it by running Windows Update first, then manually installing the latest driver from the manufacturer with admin rights.

Why This Error Pops Up

Windows 11 enforces strict driver signing, so older GPU, chipset and audio drivers often refuse to install. Antivirus tools, leftover ghost devices in Device Manager, and incomplete previous installs are the usual suspects. SA users on metered LTE also see partial downloads that look complete but break mid-install.

Step-by-Step Fix

Start by running Windows Update and rebooting. Then open Device Manager, right click the device, choose Uninstall device, and tick Delete the driver software. Download the fresh driver from the official site (NVIDIA, AMD, Intel, Realtek). Right click the installer and select Run as administrator. If it still fails, boot into Safe Mode and use Display Driver Uninstaller for graphics cards, then reinstall on a clean profile.

Common Mistakes to Avoid

Dont stack multiple driver versions on top of each other, that is the number one cause of stuck installs. Skip third party driver updater tools, they often pull mismatched versions. Never disable Windows driver signing permanently, only for a single boot if absolutely needed. And dont try to update drivers mid loadshedding without a UPS, an interrupted install can leave the device unusable.

SA-Specific Tips

Download drivers during off-peak hours if you are on uncapped LTE or fibre with shaping. Keep a copy of working drivers on a flash drive, courier turnaround for replacement components in smaller SA towns can take a few days, having offline drivers saves a build.

Frequently Asked Questions

Why does Windows say my driver is not digitally signed?

The driver was either built before Microsoft tightened signing rules or the download got corrupted. Grab the WHQL signed version from the manufacturer rather than a forum mirror.

Will reinstalling Windows fix Cannot Update Driver?

Usually yes, but try DISM and SFC scans first. Open an admin command prompt and run sfc /scannow followed by DISM /Online /Cleanup-Image /RestoreHealth, that fixes most driver store corruption.

Do I need a special tool to remove old GPU drivers in SA?

Display Driver Uninstaller is free and works perfectly. Run it from Safe Mode for the cleanest result, then install the latest GeForce or Adrenalin driver fresh.
