Windows Server 2012: Pending restart but after restart it still says pending restart endlessly.
Restart required
Security Update for Microsoft Windows (KB4571736)
Status: Pending restart

I have tried many Windows Update tools such as:

A user having similar problem but is for Window 10. The user having luck and fixed it, but mine does not.

I have tried to uninstall this particular update but failed with error:
"An error has occurred. Not all of the updates were successfully uninstalled."
I have tried to restart to WinRE so that I can uninstall this particular update, but restart also has error.
Method: From the login screen, click Shutdown, then hold down the Shift key while selecting Restart.

Your help is appreciated in advanced. Thank you.

    Please try to delete the following folders or rename those folders, after that restart computer again to check.

    If the issue persists, try to uninstall this update package with the measure below:

    •  Create folder C:\temp\cab  
    •  Download the update KB4571736 from to C:\temp  
    •  Expand the .msu file to extract the .cab file by running below command in CMD: 
    •             expand -F:* C:\temp{.msu file name with extension} C:\temp\cab
    • You will get a .cab file from last step. Use the following DISM command to remove package: 
    Dism /online /remove-package /packagepath:c:\temp\cab{.cab file with extension}

    Then we could install the latest update package KB4592468 which released on December 8, 2020 instead of this one, as this one has been replaced by the latest.
