Answer 1

Hi and thanks for reaching out. My name is Bernard. I'm a Microsoft Windows expert and a Microsoft 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

After running the command line.

Do clean boot:

A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.

• In the search box on the taskbar, type msconfig and select System Configuration from the results.
• On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
• On the Startup tab of System Configuration, select Open Task Manager.
• Under Startup in Task Manager, for each startup item, select the item and then select Disable.
• Close Task Manager.
• On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Restart the PC and check it again, please ignore errors and skip the command line if you have one.

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...

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.

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.
