1] Disable antivirus

Sometimes Anti-virus software blocks file access or even disk access. It is better that you disable the Anti-Virus and Security software before initiating the upgrade.  You can either disable such software or completely uninstall them till you fix the Update issues. If you are using Windows Defender, it is easy to disable it for troubleshooting.

2] Free up disk space

Run Disk Cleanup Utility to delete junk files.

3] Remove any file protection software

When upgrading, Windows Setup migrates folder from one version to another. However, if your folders are protected using some file protection software, it will fail to move them, and you will face this error. You can either unlock all those files or uninstall the software after removing all the locked files. Post, this try to install again.

4] Rename SoftwareDistribution folder

To solve this, it is advisable to rename the SoftwareDistribution folder. Before renaming, you will need to stop the Windows Update Service and BITS Update service. Open an elevated command prompt windows, type the following commands one after the other, and hit Enter:

net stop wuauserv
net stop bits
rename c:\windows\SoftwareDistribution SoftwareDistribution.bak
net start wuauserv
net start bits
