Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

Just to confirm, have you already enrolled in Extended Security Updates (ESU)? As updates will not push through if not enrolled, since Windows 10 support ended last year.

Moreover, if you have already enrolled, this issue occurs when there is a miscalibration or corrupted system files with the Windows update, and for us to sort out the issue, kindly follow the steps below:

Reset Windows update components:

Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))

Copy each line of command, then press Enter (one line at a time)

net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"
rmdir %systemroot%\SoftwareDistribution /S /Q
rmdir %systemroot%\system32\catroot2 /S /Q
regsvr32.exe /s atl.dll
regsvr32.exe /s urlmon.dll
regsvr32.exe /s mshtml.dll
netsh winsock reset
netsh winsock reset proxy
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc

Once done, restart the device and check.

If none of the above solutions work, I suggest doing an in-place upgrade, wherein it will update the device to the latest version and repair all issues without deleting any files.

 

Note: before doing this make sure to create a restore point:  https://support.microsoft.com/en-us/help/4027538/windows-create-a-system-restore-point
