 Here are some steps you can take to fix Windows 11 Update KB5028185/KB5028851 not working:

1. Run the Windows Update troubleshooter. This troubleshooter can help to identify and fix problems that are preventing Windows updates from installing. To run the troubleshooter, open the Settings app and go to System > Troubleshoot > Other troubleshooters. Scroll down and select Windows Update, then click Run the troubleshooter.
2. Restart the Windows Update and Background Intelligent Transfer Services. These services are responsible for downloading and installing Windows updates. To restart them, open the Services snap-in (press Windows+R and type services.msc and press Enter). Find the Windows Update and Background Intelligent Transfer Service services, right-click on each one and select Restart.
3. Check for corrupted system files. Corrupted system files can also prevent Windows updates from installing. To check for corrupted system files, open the Command Prompt as an administrator and type the following command:

sfc /scannow

This command will scan your system for corrupted files and attempt to repair them.

4. Download and install the updates manually. If the above steps do not work, you can try downloading and installing the updates manually from the Microsoft website. Go to the following link and click on the Download now button:

net stop cryptsvc
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\Catroot2 Catroot2.old
