I’m sorry to see that you marked my reply as not helpful.
Have you tried resetting the update components?
Open cmd prompt/powershell with admin & enter:
net stop wuauserv
net stop cryptSvc
net stop bits
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
Restart the PC & try updating again.
Try regedit in the search bar & right click on it to choose run as admin, then find: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate & delete the entries WUServer and WIStatusServer in the right pane.
Restart the computer and try to install the updates again.
Check too for malware:
Try running these programs:
MBAM free: https://www.malwarebytes.com/mwb-download/
Eset online scanner: http://www.eset.com/us/online-scanner/
Adwcleaner: https://www.malwarebytes.com/adwcleaner/
If these find one or more infections but do not fully remove them it will be wise to register with a malware removal site to receive dedicated malware removal instructions, an expert will remain with you throughout the process until confirmation that your PC is 100% clean.
