Windows Update error 0x80070002: what it means and what to try first

Microsoft groups 0x80070002 among update install failures; preserve the context before using broader repair steps.

Applies to: Windows 11Reviewed: 2026-09-17

What it means in this context

For current Windows Update guidance, Microsoft lists 0x80070002 among error codes where an update failed to install. The same hexadecimal code can appear in other Windows contexts, so this page is specifically for Windows Update—not every possible 0x80070002 occurrence.

Start here
  1. Confirm the code appeared in Windows Update.
  2. Record the failing KB/update name.
  3. Restart the PC and retry once.
  4. Run the Windows Update troubleshooter.

Run the Windows Update troubleshooter

Low risk

Why: This is Microsoft’s first-line Windows Update troubleshooting path for current Windows 11.

  1. Open Get Help.
  2. Run the Windows Update troubleshooter.
  3. Apply the identified fixes and restart if requested.

Repair system files if the failure persists

Medium risk

Why: If damaged Windows components are contributing, DISM followed by SFC is the official system-file repair order.

  1. Open Windows Terminal as administrator.
  2. Run DISM RestoreHealth.
  3. Run SFC after DISM completes.
  4. Restart and retry the update.
DISM.exe /Online /Cleanup-Image /RestoreHealth

When not to use this record

If 0x80070002 appears during Windows setup, app installation, backup, or another subsystem rather than Windows Update, do not assume this update-specific guide applies.

If it persists

If the same KB fails again, collect the KB number and the update history result. A future deeper record should branch by update type instead of pretending one reset fixes every instance.
