- Right-click on the antivirus icon in the system tray and select Disable or Turn off.
- Choose the appropriate duration (e.g., 15 minutes, 1 hour) or disable it until the system restart.
- Attempt to install the KB5001716 update again.
Remember to re-enable your antivirus software once the update has been installed.
3. Repair Corrupted System Files
Corrupted system files can be a significant cause of update errors. To repair these files, you can use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) utilities:
Step 1: Run the SFC Scan
- Open the Command Prompt as an administrator by pressing Win + X and selecting Command Prompt (Admin).
- Type sfc /scannow and press Enter.
- Wait for the scan to complete. If any corrupted files are found, the tool will attempt to repair them automatically.
Step 2: Run the DISM Tool
- In the same Command Prompt window, type the following command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth - Allow the process to complete, which may take some time.
- Restart your computer and try installing the update again.
4. Reset Windows Update Components
If the previous steps didn’t resolve the issue, resetting the Windows Update components might help:
- Open Command Prompt as an administrator.
- 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:\Windows\SoftwareDistribution SoftwareDistribution.old
- ren C:\Windows\System32\catroot2 catroot2.old
- net start wuauserv
- net start cryptSvc
- net start bits
- net start msiserver
- Close the Command Prompt and try the update again.
5. Manually Install the KB5001716 Update
If the error persists, you can try manually installing the KB5001716 update:
- Visit the Microsoft Update Catalog website.
- Search for KB5001716 and download the appropriate version for your system.
- Once downloaded, double-click the file to begin the installation.
Manual installation bypasses the standard Windows Update process, which may help avoid the 0x80070643 error.
6. Check for .NET Framework Issues
The .NET Framework is often involved in Windows updates, and issues with it can cause the 0x80070643 error. Here’s how to check and repair it:
- Press Win + R, type appwiz.cpl, and press Enter to open Programs and Features.
- Click on Turn Windows features on or off in the left pane.
- Ensure that the .NET Framework 3.5 (includes .NET 2.0 and 3.0) and .NET Framework 4.8 Advanced Services are enabled.
- If they are enabled, try turning them off, restarting your computer, and then re-enabling them.
After ensuring the .NET Framework is correctly installed and enabled, try installing the update again.
Advanced Solutions for Persistent Errors
If none of the above methods work, more advanced troubleshooting may be necessary. These solutions involve deeper system modifications and should be attempted if you are comfortable with advanced system management.
7. Perform a Clean Boot
A clean boot starts Windows with a minimal set of drivers and startup programs, which can help you determine if background programs are interfering with the update:
- Press Win + R, type msconfig, and press Enter.
- Go to the Services tab and check Hide all Microsoft services.
- Click Disable all, then go to the Startup tab and click Open Task Manager.
- Disable all startup items in Task Manager, then close it and click OK in the System Configuration window.
- Restart your computer and try installing the update again.
If the update is successful in a clean boot environment, it indicates that a third-party service or startup item was causing the conflict.
8. Use the Windows Update Assistant
The Windows Update Assistant is a tool provided by Microsoft to help users manually install updates that are failing through the usual update process:
- Download the Windows Update Assistant from the official Microsoft website.
- Run the tool and follow the on-screen instructions to install the KB5001716 update.
This method bypasses potential issues with the Windows Update service, making it a good option for persistent errors.
Preventing Future Update Errors
To avoid encountering similar errors in the future, consider implementing the following best practices:
1. Regularly Maintain Your System

2. Keep Software and Drivers Updated
- Regularly update your drivers and software to avoid compatibility issues with new Windows updates.
