download error -0x80070020 when installing this update Kb5060841

Hello, 

Thank you for reaching out on Microsoft Q&A. The error code 0x80070020 translates to ERROR_SHARING_VIOLATION. In simple terms, this means the Windows Update process is trying to access or modify a file that is currently locked or in use by another program on your system. 

The most common culprits are: 

• Antivirus or Security Software: Real-time scanning can lock files that the update needs to replace. 
• Backup Software: A backup process running in the background. 
• Other System Utilities: Any application that might monitor system files. 

Please try the following solutions in order.  

1. Clean Boot 

• Press Windows + R, type msconfig, and press Enter 
• Go to the Services tab, check Hide all Microsoft services, and click Disable all 
• Go to the Startup tab and click Open Task Manager 
• Disable all startup items 
• Restart your computer and try updating again 

2. Run Windows Update Troubleshooter 

• Go to Settings > Update & Security > Troubleshoot 
• Select Windows Update and click Run the troubleshooter 

3. Reset Windows Update Components 

1. Open Command Prompt as an administrator 
2. Stop the BITS, Cryptographic, MSI Installer, and Windows Update Services: 

net stop wuauserv 
net stop cryptSvc 
net stop bits 
net stop msiserver 

3. Rename the SoftwareDistribution and Catroot2 folders: 

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old  
ren C:\Windows\System32\catroot2 Catroot2.old 

4. Restart the services: 

net start wuauserv 
net start cryptSvc 
net start bits 
net start msiserver 

5. Restart your computer and try updating again 

4. Disable Antivirus Temporarily 

Sometimes, antivirus software can interfere with the update process. Temporarily disable your antivirus software and try updating again.
