Hello,
What is the error message for the update failure? Can you provide a screenshot of the error?
Can you download and install the cumulative update in January?
Here are some basic troubleshooting steps you can try:
1.Running the update troubleshooter. Select Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update > Run the troubleshooter.
2.Manually downloading the updates from Microsoft Update Catalog.
3.Performing a clean boot. This is a way of starting Windows with only the essential services and programs, which can help eliminate any software conflicts that might interfere with the update process. Please refer to this link: https://support.microsoft.com/en-us/topic/how-to-perform-a-clean-boot-in-windows-da2f9573-6eec-00ad-2f8a-a97a1807f3dd
4.Restarting the update services. You can do this by using the Services tool (services.msc) and stopping and starting the following services: Windows Update, Background Intelligent Transfer Service, and Cryptographic Services.
5.Check if there is enough disk space available on your system drive. If not, free up some space and try the update again.
