How to Fix Windows Update Error Code 80070308 on Windows 11: Step-by-Step Solutions

Windows Update error code 80070308 can be frustrating, especially when you want to keep your Windows 11 system up to date. This error often appears when the update process encounters unexpected issues. Fortunately, there are straightforward ways to resolve it.

In this guide, we will walk you through simple and detailed solutions to fix this error. Each step is explained clearly, so even beginners can follow along without confusion.

By the end of this article, you should be able to get your updates working smoothly again. Let’s begin with a few quick checks before diving into the fixes.

Make sure you have a stable internet connection and your PC is not running low on disk space, as these can affect Windows Update.

Quick Note: Prerequisites and Initial Checks

  • Check your internet connection: A stable and fast connection helps Windows Update download files without interruptions.
  • Free up disk space: Ensure at least 10 GB of free space on your system drive to accommodate update files.
  • Restart your PC: Sometimes, a simple reboot can clear temporary glitches causing the error.
  • Disable third-party antivirus temporarily: Some security software can interfere with updates.

Step 1: Run the Windows Update Troubleshooter

Windows 11 comes with a built-in troubleshooter that detects and fixes common update problems automatically. Running it is a simple first step.

  1. Click on the Start button and select Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click the Run button next to it.
  4. Follow the on-screen instructions. The troubleshooter will scan for issues and attempt to fix them.
  5. After completion, restart your PC and try updating again.

This tool is important because it automates many common fixes that could be causing error 80070308.

Step 2: Reset Windows Update Components Manually

If the troubleshooter didn’t solve the problem, resetting the update components can fix corrupted files or settings preventing updates.

Follow these steps carefully. You will use the Command Prompt with administrator privileges.

  1. Press Windows + S, type cmd, right-click on Command Prompt, and select Run as administrator.
  2. In the Command Prompt window, type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

These commands stop the update services, rename the folders where updates are stored (forcing Windows to recreate them), and then restart the services. This process clears corrupted data that might be causing the error.

Once done, close the Command Prompt and restart your computer.

Step 3: Check System Files with SFC and DISM Tools

Corrupted system files can interfere with Windows Update. The System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can scan and repair these files.

  1. Open Command Prompt as administrator again.
  2. Type the following command and press Enter:
sfc /scannow

This scan may take some time. It will automatically repair any corrupted files it finds.

  1. After SFC completes, run these two commands one by one:
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

DISM checks the Windows image and repairs any issues found. Running both SFC and DISM ensures your system files are intact and ready for updates.

Restart your PC after these processes finish and try updating again.

Step 4: Temporarily Disable Firewall and Antivirus Software

Sometimes, security software blocks Windows Update from working properly. Temporarily disabling your firewall and antivirus can help identify if this is the cause.

  • Open your antivirus program and look for an option to disable it temporarily (usually found in settings or system tray menu).
  • For Windows Defender Firewall, go to Settings > Privacy & Security > Windows Security > Firewall & Network Protection. Click on your active network and toggle off the firewall.

Try running Windows Update again after disabling security software. If the update works, re-enable your protections afterward and consider adjusting settings or adding exceptions for Windows Update.

Step 5: Perform a Clean Boot

A clean boot starts Windows with only essential services, preventing other programs from interfering with updates.

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check the box for Hide all Microsoft services, then click Disable all.
  4. Switch to the Startup tab and click Open Task Manager.
  5. In Task Manager, disable all startup items one by one.
  6. Close Task Manager and click OK in the System Configuration window.
  7. Restart your PC.

Now, try updating Windows again. If the update works, this means a third-party app was causing the error. You can re-enable services and startup items gradually to find the culprit.

Alternative Advanced Option: Use the Windows Update Assistant

If none of the above solutions work, you can use the Windows Update Assistant. This official Microsoft tool helps manually install the latest updates and upgrade Windows.

Simply download the tool, run it, and follow the instructions. This method bypasses some update issues but should be used carefully, as it performs a major update process.
