If you instead would like to take a more hands-off approach, you can always rely on automatic tools such as [d1].

Fix 1. Check if relevant services are running

Ensuring that crucial Windows services related to updating are active and set to automatically start can resolve issues where updates fail to initiate or complete. Services such as the Windows Update service and Background Intelligent Transfer Service (BITS) play key roles in the update process. If these services are stopped or set to manual start, it may prevent updates from being downloaded or installed.

• Type in Services in Windows search and press Enter.
• Scroll down to locate Background Intelligent Transfer Service (BITS).
• If it is already running, right-click and pick Restart.
• If the service is not running, double-click it, select Automatic under the Startup type from the drop-down menu.
• Click Start, Apply, and OK.
• Perform the same steps with Windows update and Cryptographic services.

Fix 2. Run Windows Update troubleshooter

The Windows Update troubleshooter is a built-in tool that can automatically find and fix common problems with Windows Update. Running this troubleshooter can resolve issues by resetting update components, clearing caches, and fixing corrupted files.

• Type Troubleshoot in Windows search and press Enter.
• Click Additional troubleshooters.
• Scroll down to find the Windows Update option.
• Click and select Run the troubleshooter.
• Apply the offered changes and close down the troubleshooter - see if that helps solve your problem.

Fix 3. Perform Disk Cleanup

Disk Cleanup can free up space on your hard drive and remove temporary files that might be interfering with the update process. Clearing out these files can sometimes resolve update installation issues.

• In the Windows search bar, enter Disk Cleanup, then press Enter to launch the utility.
• Pick the main drive (C: by default) and select the option for Clean up system files.
• Choose the drive once more and press OK.
• From the array of files that can be cleaned, choose those taking up the most space, for example, Temporary Internet Files, Windows Update, and Temporary Files, among others.
• Hit OK to begin the cleanup process.

Fix 4. Repair corrupted system files

The System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools can repair corrupted Windows system files. Corrupted system files can prevent updates from installing correctly.

• Type cmd in Windows search.
• Right-click on Command Prompt and pick Run as administrator.
• User Account Control will ask you whether you want to allow changes – click Yes.
• Copy and paste this command and hit Enter:
  sfc /scannow
• Wait for the scan to finish.
• As soon as it finishes, Windows will report whether integrity violations were found and if they could be fixed. Regardless of the outcome, use these commands next, pressing Enter after each:
  Dism /Online /Cleanup-Image /CheckHealth
  Dism /Online /Cleanup-Image /ScanHealth
  Dism /Online /Cleanup-Image /RestoreHealth
• Close down the Command Prompt and restart your device.

Fix 5. Reset Windows update components

Resetting Windows Update components manually can fix updates that won't install or get stuck. This involves stopping update services, clearing cache folders, and restarting the services.

• Open Command Prompt as administrator.
• Stop the Windows Update Services by entering the following commands, one at a time, and pressing Enter after each:
  net stop wuauserv
  net stop cryptSvc
  net stop msiserver
  net stop bits
• Rename the SoftwareDistribution and Catroot2 folders with the following commands:
  ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
  ren C:\Windows\System32\catroot2 catroot2.old
• Restart the services you stopped earlier with these commands:
  net start wuauserv
  net start cryptSvc
  net start msiserver
  net start bits
• Close the Command Prompt window and try running the Windows Update again.

Fix 6. Install the update manually

If automatic updates fail, downloading and installing the update manually from the Microsoft Update Catalog can bypass issues with the Windows Update service.

• Open your browser and go to Microsoft Update Catalog.
• Within the search bar, type in KB5034582 and click Search.
• Find the correct version of the update for your operating system (to check this, right-click on Start and pick System. Under Device specifications and check the System type) and click Download.
