Hi and thanks for reaching out. My name is Bernard an Independent Advisor and a Windows fan like you. I'll be happy to help you out today.

I actually have same issue as before and by following the steps provided below fixed my issue, I hope this works for you as well

I know some methods are already done, but it it better if you follow this step by step:

First method is to reset the Windows update components using the powershell command below.

This method will reset the Software distribution folder where the temporary file of update is saved, and re register internet connect as well.

Open Powershell with Admin or CMD with Admin (Press Windows key + X then click Windows Powershell(Admin))

Copy each line of command to Powershell 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

Restart the device and check it again just ignore any error in command line if you encounter.

If none will work from the above solution I suggest to do an in-place upgrade wherein it will upgrade 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-hk/help/402753...

1. go to this link: https://www.microsoft.com/en-us/software-downlo...
2. Select Download tool, and select Run. You need to be an administrator to run this tool.
3. On the License terms page, if you accept the license terms, select Accept.
4. On the What do you want to do? page, select Upgrade this PC now, and then select Next.
5. After downloading and installing, it should fix the issue.

Reference: https://www.microsoft.com/en-us/software-downlo...

Note: if you receive error: “This Pc can’t be upgrade, follow the steps below”

Method 1. Go to C:$WINDOWS.~BT\Sources\Panther then delete the file name compatscancache.dat

Then try again or reboot the PC first then try again.

You might not see the folder as it is hidden, make sure to show hidden files first.

Let me know how does it goes and I hope that helps.
