Hi there,
I am not very clear about the issue you are facing. If you are in an dilemma of updating the PC I would strongly suggest you PC to update t the latest version for security and smooth operation.
You don't need to read or understand before updating your PC. During the updating process, the Windows Update Orchestrator operates in the background to scan, download, and install updates. It does these actions automatically, according to your settings, and silently so that doesn't disrupt your computer usage.
You can read more about this from the below article https://learn.microsoft.com/en-us/windows/deployment/update/how-windows-update-works
