Windows 11 couldn’t connect to the update service (solved)

Windows Updates include essential security patches to protect your system from the latest security threats and vulnerabilities. Regular updates from Microsoft address bugs and issues, enhance system stability, and minimize unexpected errors. However, at times, while trying to update your Windows 10 or 11 PC, you may encounter an error message that says

“We couldn’t connect to the update service. We’ll try again later, or you can check now.”

This error means that your PC is unable to communicate with the Microsoft servers that provide the latest updates for your system. This article explores what causes this error and how to fix the Windows 11 Update error: We couldn’t connect to the update service.

We couldn’t connect to the update service

This error can occur due to various reasons, including internet connectivity issues, misconfigured network settings, corrupted system files, or problems with the Windows Update components. Some of the most common ones are:

• A stable internet connection is essential for the update service to communicate with Microsoft servers. Connectivity problems, such as a weak signal or issues with the internet service provider, can lead to this error.
• Incorrect date and time settings, VPN or proxy configurations, or issues with Windows Update components may disrupt the connection, resulting in the error.
• Third-party antivirus programs or security software might interfere with the update process. Temporarily disabling such software can help identify if they are causing the connectivity problem.
• Over time, the update cache and components may become corrupted, leading to connectivity issues. Manually resetting these components can often resolve the problem.
• Your device has a firewall or antivirus software that is blocking the connection to the update service.

Check Your Internet Connection

Windows Update needs a stable internet connection to contact Microsoft’s servers. If your connection is unstable, disconnected, or using a restricted network, Windows can’t download updates.

Make sure that your PC is connected to a stable and fast network.

• You can use a speed test tool to measure your connection speed and quality,
• You can try to restart your router or modem, or use a different network if possible.
• Verify that you can access other websites and online services without any problems.
• If using a Wi-Fi connection, try connecting via Ethernet to rule out any wireless connectivity issues.

Restart Your Computer

Sometimes, A simple restart can often resolve temporary glitches that might be affecting the update service. It clears the system’s memory and restarts essential processes.

• Save your work and close all open applications.
• Click on the Start menu, select the power icon, and choose “Restart.”

Reset TCP/IP Stack and Flush DNS

Corrupted network settings or DNS cache can block Windows from reaching update servers. Resetting TCP/IP and clearing DNS forces Windows to reinitialize its network configuration.

• Press Windows + S, type cmd, and right-click Command Prompt → Run as administrator.
• Run the following commands one by one:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

• Once all commands are executed, close the command prompt and restart your computer.
• Now check for updates again from Settings → Windows Update.

Restart Windows Update Services

Windows relies on background services like Windows Update, BITS, and Cryptographic Services to download and install updates. If these services are stopped or stuck, Windows can’t connect properly.

• Press Windows + R, type services.msc, and press Enter.
• Locate Windows Update service, Right-click on it, select restart
• If the service is not started, right-click and select Ensure their Startup type is set to Automatic. Double-click on it and change the Startup type to Automatic.

In addition, start/restart the Background Intelligent Transfer Service (BITS) and the Cryptographic Services.

Close the window and try to check and install Windows updates again.

Change DNS Server to Google or Cloudflare

DNS (Domain Name System) servers translate website and service addresses. If your current DNS server is slow or blocked, Windows may fail to reach the update service.

• Press Windows + R, type ncpa.cpl, and hit Enter.
• Right-click your active network adapter → Properties.
• Select Internet Protocol Version 4 (TCP/IPv4) → Properties.
• Choose Use the following DNS server addresses:

Preferred: 8.8.8.8
Alternate: 8.8.4.4
(or Cloudflare’s DNS: 1.1.1.1 and 1.0.0.1)

Click OK and restart your PC. Try checking for updates again.

Run the Windows Update Troubleshooter

The Windows Update Troubleshooter is a built-in tool designed to automatically detect and fix common issues that can prevent updates from being installed.

• Press Win + I to open the Settings menu
• Go to the system, then troubleshoot and click on Other troubleshooters
• Click Run next to the window update and follow the on-screen instructions to diagnose and fix Windows update errors automatically.

This will attempt to identify if any problems exist that prevent your computer from downloading and installing Windows Updates.

• Apply any recommended fixes and restart your PC.

Reset Windows Update Components Manually

If Windows Update’s internal cache or database is corrupted, it can’t connect or download updates correctly. Manually resetting components rebuilds the update infrastructure.

• Open Services: Press Win + R, type services.msc, and press Enter.
• Stop Windows Update: Find “Windows Update” in the list, right-click it, and select “Stop”.
• Navigate to the cache folder: Open File Explorer and go to C:\Windows\SoftwareDistribution\Download.
• Delete the files: Select all files and folders inside the Download folder and delete them. You may need to confirm with a User Account Control (UAC) prompt.
• Restart the service: Go back to the Services window, find “Windows Update,” right-click it, and select “Start”.

Go to Settings → Windows Update → Check for updates again.

Check Date and Time Settings

Incorrect date and time settings can interfere with Windows Update. Ensuring the correct date and time is crucial for the system to establish a secure connection with Microsoft servers.

• Open the Settings menu (Win + I), go to “Time & language.”
• Verify the date, time, and time zone settings.

Make sure that the option “Set time automatically” is turned on, or manually adjust the date and time to match your time zone.

Temporarily Disable Antivirus or Firewall

Some third-party antivirus programs may interfere with Windows Update. You can try to turn off your firewall or antivirus software for a while and see if the error goes away. Remember to turn them back on after you finish updating your PC.

• Temporarily disable your antivirus software.
• If using a third-party firewall, turn it off for testing.
• Try checking for updates again.
• Re-enable your antivirus after the update completes.

Run SFC and DISM Scans to Repair Corrupted System Files

Damaged or missing system files can interrupt the Windows Update process or block access to update servers. Running SFC (System File Checker) and DISM (Deployment Image Servicing and Management) helps repair these files and restore system stability.

• Press Windows + S, type cmd, right-click it → choose Run as administrator.
• Type sfc /scannow and hit the Enter key.
• This will check for missing, corrupted system files
• If found any the utility will restore them from %WinDir%\System32\dllcache.
• Wait until 100% complete the scanning process After that, restart Windows and check for updates.

Also, if the SFC scan fails to restore corrupted system files, simply run the DISM command, which repairs the system image and enables SFC to do its job. DISM /Online /Cleanup-Image /RestoreHealth.

Once both scans are complete, restart your computer and try updating Windows again.
