TLDR: Installed Windows multiple times, Installed Updates, Error Code everytime

I helped my brother build his PC yesterday and we got Windows 10 installed but we needed to download all the Windows updates to even install his Nvidia drivers. All was good until we got to this error. So we tried everything we could yesterday to no avail. Today I formatted and reinstalled Windows and tried everything all over but once again was met with this same exact error code. The code says it has to do with a security patch with Adobe Flash. I've had this Windows 10 disk since 2016 and have used it a plethora of times including a different build last month with no problems but here we're running into the same problem multiple times on the same build. Does anyone know how to resolve this issue? Basic googling and trying some of the front page methods hasn't worked so far. Thanks for any tips or advice.

Why do you waste your time with an old version of Windows 10, which you then have a million updates to do to catch up to right now, when you can simply install the latest version?

Click on the blue button "Download Tool now", insert a USB flash drive (it will be formatted by the tool, so make sure it doesn't have any data). Faster the USB flash drive the better. Needs to be 8GB or more. Run the tool, pick "For another PC", when asked. And it will download the latest version of Windows 10, format your USB flash drive, extract all content downloaded to it, and makes it bootable. Just eject safely and plug it on the system you want to install Windows 10, and boot from it, and you are good to go. Setup process is the same as on disk, you'll just get started with the latest version/build.

If you are incline in fixing your error. The error code you have under Windows Update, is an unspecified one. Meaning, it is an unexpected error that has occurred, and no definition associated to it. In other words, you need to check the logs files and event viewer, and see what fails, and why.

Typically running the Troubleshooter for Windows Update will fix this kind of errors, where the troubleshooter would clean everything and allow you to redo the update form a clean state. To run the Troubleshooter: Settings > Update & Security > Troubleshoot > Windows Update (if I recall correctly).
