Perform an SFC scan and temporarily disable your antivirus software and see if that helps. If it does not, then proceed.
1] Rename the Catroot2 and Software Distribution folders
When Windows downloads the updates, they are kept in a dedicated folder called as Software Distribution. Files download here are automatically deleted once the installation is complete. However, if it doesn’t clean up or if an installation is still pending, you have two choices. First, rename the SoftwareDistribution folder after pausing Windows Update Service. Next, reset the catroot2 folder.
2] Run the Windows Update Troubleshooter
Some users have reported that running the Windows Update Troubleshooter fixed the problem for them. You could try running it before proceeding with further troubleshooting.
Click on Start > Settings > Updates and Security > Troubleshoot. Then select the Windows Update troubleshooter and run it. Restart the system after that.
