How to Solve Error Code 0x80070174

There are several troubleshooting steps you can take to resolve error code 0x80070174. It's recommended to try these solutions in order:

Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter designed to identify and fix common update issues. To access it, open Settings by pressing the Windows key + I, then navigate to Update & Security > Troubleshoot. Select Windows Update from the list and click Run the troubleshooter. Follow the on-screen instructions.

Check Disk Space

Ensure you have enough free space available on your hard drive. To check disk space, open File Explorer and right-click on your main drive (usually C:). Select Properties, then view the "Free space" value. Aim for at least 10 GB of free space.

Disable Antivirus Temporarily

Temporarily disable your antivirus software to see if it's interfering with the update process. Remember to re-enable it afterward.

Reset Windows Update Components

Resetting the Windows Update components can often resolve update-related errors. To do this, open Command Prompt as an administrator (right-click on the Start menu and select "Command Prompt (Admin)") and run the following commands one by one:

  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver

Then, rename the SoftwareDistribution folder to SoftwareDistribution.old:

  • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Finally, restart the services:

  • net start wuauserv
  • net start cryptSvc
  • net start bits
  • net start msiserver

Perform a System File Check

Use the System File Checker tool to scan for and repair corrupted system files. Open Command Prompt as an administrator and run the command:

  • sfc /scannow

The process may take some time, so be patient and let it complete.

Run the DISM Tool

The Deployment Image Servicing and Management (DISM) tool can help repair system image corruption. Open Command Prompt as an administrator and run the following commands:

  • DISM /Online /Cleanup-Image /RestoreHealth

This process may also take some time, so allow it to complete.

Clean Boot Windows

Starting your computer in "Clean Boot" mode disables non-essential startup programs and services, which can help identify if a third-party program is causing the conflict. To enter Clean Boot mode, press Windows key + R to open the Run dialog box. Type msconfig and click OK. Go to the Services tab, check "Hide all Microsoft services", then click Disable All.

Go to the Startup tab and click Open Task Manager. Disable all startup items. Close Task Manager and click Apply and OK in the System Configuration window. Restart your computer in Clean Boot mode.

If the error resolves in Clean Boot, re-enable services and programs one by one to identify the culprit.
