Hi, I'm Bernard. I'm happy to help!

Have you already enrolled in Extended Security Update(ESU)? Windows 10 update already ended last October 2025, and the option to run an update is by enrolling in ESU. If you are not yet enrolled, kindly follow the steps provided in the link below:

If you are already enrolled and still having an issue, kindly follow the steps below:

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.

Note: If the issue persists, a system repair might be necessary.
