If you’re encountering the Windows Update error 0x800705b4, it’s likely due to a timeout in the update process or conflicts within your system, which prevent essential updates from being installed. This often stems from interference by third-party antivirus software, corrupted files, or incorrect update configurations. Below are comprehensive methods to help you troubleshoot and resolve this issue effectively.
1. Utilize the Windows Update Troubleshooter
The Windows Update Troubleshooter is a powerful built-in tool designed to diagnose and fix common update-related problems automatically. This is typically the best first move on your path to resolving update issues.
Step 1: Open the Settings panel by pressing Windows + I. Click on System, and select Troubleshoot from the menu on the right sidebar.
Step 2: Choose Other troubleshooters from the list.
Step 3: Click the Run button next to Windows Update and follow the on-screen instructions. Once done, try updating Windows again to see if the issue persists.
2. Temporarily Disable Your Third-Party Antivirus
Sometimes, third-party antivirus programs inadvertently block Windows updates. Temporarily disabling your antivirus can help determine whether it is the culprit.
Step 1: Locate the antivirus icon in your system tray (the area near your clock).Right-click on it and look for an option like “Disable protection”or “Pause protection.”Set a short duration, such as 10 to 15 minutes.
Step 2: After disabling the antivirus, attempt to run Windows Update again through the Settings. If the updates install successfully, consider adjusting the antivirus settings or switching to another solution.
3. Reset Windows Update Components
Corrupted components can lead to error 0x800705b4. Resetting these components may resolve the problem.
Step 1: Open Command Prompt in administrator mode by typing “cmd”in the search bar, right-clicking on Command Prompt, and selecting “Run as administrator.”
Step 2: Enter the commands below one at a time, pressing Enter after each:
net stop wuauserv net stop cryptSvc net stop bits net stop msiserver
Step 3: Rename the update folders using these commands:
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 Catroot2.old
Step 4: Restart the services by inputting this command:
net start wuauserv net start cryptSvc net start bits net start msiserver
Once these commands are executed, restart your computer and attempt the update once more.
4. Conduct System File Checker (SFC) and DISM Scans
Corrupted system files can prevent Windows updates from occurring. SFC and DISM scans are effective for repairing these files automatically.
Step 1: Open Command Prompt as an administrator as detailed previously.
Step 2: At the command line, type sfc /scannow and hit Enter. Wait patiently for the scan to complete; it could take a few minutes.
Step 3: If issues continue, initiate a DISM scan by typing this command:
DISM /Online /Cleanup-Image /RestoreHealth
Step 4: Let the DISM scan finish, then restart your PC and try running the Windows Update again.
5. Change the Windows Update Service Startup Type
Adjusting the startup type of the Windows Update service can remedy timing conflicts that prompt the 0x800705b4 error.
Step 1: Press Windows + R, type services.msc, and hit Enter.
Step 2: Locate “Windows Update”from the list, right-click it, and select “Properties.”
Step 3: Set the “Startup type”to “Automatic (Delayed Start), ”click “Apply, ”then “OK.”Afterward, restart your computer and try the update process again.
6. Manually Download and Install the Update
Should automatic updates continue to fail, manually downloading and installing the update from the Microsoft Update Catalog serves as an effective alternative.
Step 1: Identify the update that is causing the problem by noting its KB number from the Windows Update settings.
Step 2: Navigate to the Microsoft Update Catalog, input the KB number into the search bar, and download the correct file for your operating system.
Step 3: Open the downloaded file and follow the instructions on the screen to manually install the update.
By following these methods, you should be able to overcome the Windows Update error 0x800705b4, paving the way for a smoother update experience. Happy updating!
