I have been trying to install 1909 for the last few days and I cannot for whatever reason. I have tried using cmd to stop/start the server settings and delete the download folder and tried the update assistant but that yielded error code 00x900700c1.
I cannot determine what is causing my updates to fail.

First and foremost make a backup of your current state just in case something goes wrong.
If you just want to install the 1909 or the next major release of Windows 10 I would recommend using the In-Place Upgrade functionality with the Windows Media Tool or Image. This typically bypasses issues with the Windows 10 update service and also fixed them after installation for me.
If you want to fix the underlying issue with the Update Service, often clearing the update cache helps. Something like that brought up a quick Google search. There might be better ways to clear the cache but you can easily find different approaches online.
