Hello Edmund LJJ,
I suggest that you try the following steps:
- Check if the update is already installed: Go to Control Panel > Programs and Features > View installed updates. Look for the KB5028623 update and check if it is already installed.
- Check if the update is applicable to your system: Make sure that the update is applicable to your system. Check the system requirements and the version of Windows Server that you are using.
- Check if there are any pending updates: Go to Settings > Update & Security > Windows Update and check if there are any pending updates. If there are, install them first before installing the KB5028623 update.
- Check if there are any third-party antivirus or firewall programs: Disable any third-party antivirus or firewall programs temporarily and try installing the update again.
If the issue persists, please provide me the error code and the error message.
Kind regards,
Lei
