@OllieSaleh Thanks for posting in our Q&A. I quite understand your confusion about this issue.
In fact, someone has discussed in the following link:
https://techcommunity.microsoft.com/t5/microsoft-intune/windows-10-quality-updates-update-healt-tool-missing/m-p/2453650
From your description, it seems that you failed to install Microsoft Update Health Tools via some methods. I think we should focus on why didn't install the Update Health tool automatically during update.
Given this situation, it is needed to check the background information to find the root cause. With Q&A limitation, it is suggested to create an online support ticket to handle this issue more effectively. It is free. Here is the online support link:
