Effective Methods to Fix Error 0x80070057

The good news is that multiple strategies can effectively resolve this error. Start with the simpler solutions and proceed to more advanced ones as needed.

1. Check for Windows Updates

Before diving deep, make sure your system is up to date. Ironically, although updates can trigger the error, they can also fix it.

• Click Start > Settings > Update & Security
• Click Check for updates
• If available, install all updates and restart your computer

2. Run Windows Update Troubleshooter

This built-in tool automatically finds and fixes update-related issues.

• Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters
• Select Windows Update and click Run the troubleshooter

Follow the prompts and restart your device when finished.

3. Use the System File Checker (SFC)

SFC is a command-line utility that scans and repairs corrupted or missing system files.

1. Type cmd in the Windows search box
2. Right-click on Command Prompt and choose Run as administrator
3. Type sfc /scannow and press Enter

This process might take a few minutes. Once done, restart your PC and check if the issue persists.

4. Manually Reset Windows Update Components

If the troubleshooter didn’t help, you might need to manually reset the update components:

1. Open Command Prompt as an administrator
2. Type the following commands one by one:
   • net stop wuauserv
   • net stop cryptsvc
   • net stop bits
   • net stop msiserver
3. Rename the SoftwareDistribution and Catroot2 folders:
   • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
   • ren C:\Windows\System32\catroot2 Catroot2.old
4. Restart the services:
   • net start wuauserv
   • net start cryptsvc
   • net start bits
   • net start msiserver

Restart your PC and check if Windows Update now works correctly.

5. Edit the Registry (Carefully!)

If the issue seems to be related to backing up data or installing programs, a registry tweak might help:

1. Press Windows Key + R, type regedit and press Enter
2. Navigate to:
   • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX
3. If you don’t see a Settings key, create it
4. Create a new DWORD (32-bit) Value named AllowUserWUAccess and set its value to 1

Important: Always back up your registry before making changes. Incorrect modifications can lead to system instability.

6. Perform a Disk Check

If your storage drive is developing bad sectors, it can result in Windows being unable to write properly, triggering the 0x80070057 error. Here’s how to check:

1. Open Command Prompt as an administrator
2. Type chkdsk /f /r and press Enter
3. It might prompt you to schedule the disk check on the next restart. Type Y and press Enter

Restart your computer and allow Windows to complete the disk check.

7. Check Group Policy Settings (For Advanced Users)

In enterprise or professional editions of Windows, certain group policy settings might interfere with updates and backups.

• Press Windows Key + R, type gpedit.msc and hit Enter
• Navigate to Computer Configuration > Administrative Templates > System > Windows Update
• Ensure policies blocking downloads or installations are not set to “Enabled”
