EDIT: THIS IS NOW SOLVED, CHECK MY POST BELOW FOR THE CAUSE AND SOLUTION
So the time is currently 3 AM and I've tried installing Windows 10 for the 4th time. It all started when my friend sent me a text message that he Windows 10 was setting up for him. I immediately sought out to see why I was never prompted to install it (we live in the same State/Time Zone). It said I was eligible for the upgrade and that it was reserved, but still nothing about it being ready to be downloaded.
I restarted my PC and long-behold, it was downloading! It was fairly quick and took about 15 minutes. After it was complete, it suddenly said that the update failed and gave me an error code of C1900204. I was upset by this and started searching around, and no luck what-so-ever. I went ahead and tried to re-install it, and it downloaded fine, but once again came up with that error. I restarted my PC and tried again, nothing.
I began to think that maybe one of my system files was corrupt and so I went ahead and started to scan the system files via CMD sfc /scannow. After it ran through, luckily with no errors found, I tried to install it once more. Once again, it failed with the same error!
I have no idea why this is occurring. Also, here is a picture of my System. I blurred out the Computer name and product ID due to safety concerns.
