Make sure to save your work before proceeding, as some steps may require restarting your computer.

Quick Note

Before starting the troubleshooting process, please check the following:

  • Internet Connection: Ensure your device is connected to the internet. Windows Update requires an active connection to download updates.
  • Administrator Access: You need to be logged in with an administrator account to run some commands and make system changes.
  • Windows Version: Confirm you are running Windows 11. Some steps may differ in earlier versions.
  • Antivirus and Firewall: Sometimes, security software can block Windows Update. Temporarily disable them if necessary, but remember to enable them again later.

Step 1: Restart the Windows Update Service

Restarting the wuauserv service is often the simplest way to fix temporary glitches.

  1. Press Windows + R on your keyboard to open the Run dialog box.
  2. Type services.msc and press Enter. This opens the Services window.
  3. Scroll down and find Windows Update in the list.
  4. Right-click on Windows Update and select Restart. If the option to restart is grayed out, select Start.

This step refreshes the service and can clear minor errors preventing it from running properly.

Step 2: Run the Windows Update Troubleshooter

Windows has a built-in tool that automatically detects and fixes update-related problems.

  1. Click on the Start button and open Settings (gear icon).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Follow the on-screen instructions to let the troubleshooter identify and fix issues.

This tool is designed to fix common problems without needing manual intervention.

Step 3: Reset Windows Update Components Manually

If restarting the service and running the troubleshooter don’t help, you can reset the update components. This clears corrupted files that might be causing the issue.

  1. Open the Start menu, type cmd, then right-click Command Prompt and select Run as administrator.
  2. In the Command Prompt window, type each of the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop bits
net stop cryptsvc
net stop msiserver
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 catroot2.old
net start wuauserv
net start bits
net start cryptsvc
net start msiserver

These commands stop the update services, rename the folders where update files are stored to force Windows to recreate them fresh, and then restart the services.

Step 4: Check System Files for Corruption

Corrupted system files can cause the update service to fail. Running system scans can repair these files.

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

This command scans all protected system files and repairs corrupted ones automatically. It might take some time, so be patient.

If problems persist, run the Deployment Image Servicing and Management (DISM) tool:

DISM /Online /Cleanup-Image /RestoreHealth

This command checks for issues in the Windows image and repairs them. After it completes, run sfc /scannow again.

Step 5: Update Windows Manually

If the wuauserv service still doesn’t work properly, try downloading and installing updates manually.

  • Go to the Microsoft Update Catalog.
  • Search for the latest updates using your Windows version and system architecture (e.g., x64 for 64-bit).
  • Download the appropriate update files and run the installers manually.

This method bypasses the Windows Update service and allows you to keep your system updated.

Alternative Method: Perform a System Restore

If you recently made changes to your system and the update service stopped working afterward, restoring your PC to an earlier point may help.

  1. Search for Create a restore point in the Start menu and open it.
  2. Click System Restore and follow the wizard to choose a restore point dated before the issue started.
  3. Complete the process and restart your computer.

This will undo recent system changes without affecting your personal files.
