Completely uninstall the antivirus program or any other security program from your system. Also if possible uninstall all unnecessary third-party applications, Which may be causing conflict during the windows update installation.

Reset windows update Components
Windows Update folder (C:\Windows\SoftwareDistribution), is the location where Windows stores the new updates after downloading them. If due to any reason any file gets corrupted on the software distribution folder you may face update download and install stuck at any point or windows update fail to install with a different error code.
Clearing the folder where all of the update files are stored will force Windows Update to download afresh And fix almost every window update problem. To do this first open windows services ( Press Windows + R, services.msc and Ok ) And stop windows update related services such as BITs, Superfetch, Windows update. You can do this by right click on the service and stop.
Now Open Windows Explorer and navigate to C:\Windows folder. Here look for the folder named Software Distribution Right-click and rename it as Software Distribution.bak. Again navigate to C:\Windows\System32 look for the catroot2 folder and rename it as catroot2.bak.
Note: These are the important folders ( Software Distribution and catroot2 ) Where windows download and temporary store updates before install and apply them on the system. So renaming the folder means, When next time windows check for updates this will automatically create Software Distribution and catroot2 folder and download fresh update files.
After performing this action restart the services (BITs, Superfetch, Windows update) which you previously stopped. Now Restart windows and check for updates from settings -> update & security -> windows update and check for updates. I am sure this time you didn’t face any problem, error, update installation stuck at any certation percentage etc.
Run DISM and SFC utility
Again sometimes corrupted system files cause windows 10 updates to stuck downloading. Run the system file checker which scans and restores missing corrupted system files. If found any the utility will restore them from a special folder located on %WinDir%\System32\dllcache. Wait until 100% complete the scanning process, Then After Restart windows and check for updates. If SFC Utility Scan Results found corrupted files but unable to fix then Run DISM Tool Which enables SFC Utility to Do its job.
Also, Make Sure All Installed Device Drivers Are Updated and compatible with the current windows version. Especially Display Driver, Network Adapter, and Audio Sound Driver. You Can Check and update Them From Device manager. Run Third-party system optimizer like Ccleaner to remove junk, cache, system error, memory dump files etc and fix broken missing registry errors.
