Resolve Error 0x80070017: Troubleshoot and Fix

Man sitting in front of a computer with a metaphorical lightbulb above it.

What is 0x80070017?

Encountering error code 0x80070017 indicates that Windows has stumbled upon a data-related hiccup, more specifically, a “CRC error” when trying to read or write files during updates or installations. CRC stands for Cyclic Redundancy Check, a method used by computers to ensure the integrity of data as it’s read from a disk or transmitted over a network.

If the data’s checksum doesn’t match what was expected, Windows raises this error flag, essentially saying, “Something’s wrong with the data I’m trying to use.” It’s akin to a librarian finding pages missing from a book—without all the pages, the book (or in this case, the update process) isn’t complete.

Common Causes of 0x80070017

This error may occur due to:

  • Corrupted system files or Windows Update components.
  • Defective storage media, such as a damaged installation disc or corrupted USB drive.
  • Faulty downloads or incomplete installation files.
  • Interference from security software.

How to Diagnose 0x80070017

To verify the cause:

  • Inspect the media or source of installation files for physical damage or corruption.
  • Review the Windows Update log files for specific error messages.
  • Check the disk for errors using built-in utility tools like CHKDSK.

Step-by-Step Solutions to Fix 0x80070017

Method 1: Run Windows Update Troubleshooter

  • Access ‘Settings’, navigate to ‘Update & Security’, and select ‘Troubleshoot’.
  • Choose ‘Windows Update’ and run the troubleshooter.

Method 2: Perform a Clean Boot

  • Type ‘msconfig’ into the Start menu, select ‘Selective startup’ under the General tab, uncheck ‘Load startup items’, go to the Services tab, check ‘Hide all Microsoft services’, and then click ‘Disable all’. This will restart the computer with a minimal set of drivers and programs. If the update succeeds, one of the disabled services was causing the issue.

  • Use the CHKDSK utility by typing ‘chkdsk /f /r’ in Command Prompt (admin) to find and fix disk errors.

Method 4: Re-download or Recreate Installation Media

  • If using a USB or DVD for installation, recreate the media using a fresh ISO file.

Advanced Troubleshooting

If the issue persists:

  • Attempt a system restore to revert to a state before the error emerged.
  • For advanced users, manual repair of Windows Update components through Command Prompt might be necessary.

Professional help should be sought for:

  • In-depth system diagnostics.
