Why does Windows Update fail?

Disabled or misconfigured services, corrupted or locked delivery files, missing system directories and incorrect registry settings can stop updates from working.

Errors such as 0x800705b4, 0x80070424 or c0000022 may offer little guidance. Updates can also get stuck between 0% and 100%.

When the Windows Update Troubleshooter needs help

Update Fixer complements the official Windows Update Troubleshooter. It analyzes your computer before recommending repairs, so you can choose the operations that apply to your problem.

Missing important security and quality fixes?

Keeping Windows up to date matters for security, stability and performance. If updates fail, try the Windows Update Troubleshooter and use Update Fixer to investigate further.
