List of things I cant do due to corrupted files.

I can't Download AMD drivers. ERROR 1603. Possible Causes says Corrupted files.
I can't Download any Windows Updates gives error 0x800703f1 after completing.
I can't Download stuff from the Windows Store as it does nothing stuck on pending.
I can't Factory Reset my computer to fix this problem.
I can't update most Drivers from device manager like controllers or USB Sticks.

List of fix methods I have tried to fix my problem.

I have tried running Windows Update Troubleshooter.
I have tried running DISM and SFC.
SFC came back positive for corrupted files and it said they weren't able to fix some.
I have tried Factory Resetting, but it said unable to complete changes, undoing changes.
I have also tried downloading a IOS Windows installation to repair these files but it says unable to install windows 10>
I have tried getting a USB and was going to put an ISO File to do it on boot settings, but the problem was that my system can't read the USB in the first place -
because the "driver is unavailable".



I would love to try and fix my problem, any methods that I can try?

Also let me know if you need to know the SFC CBS.log file or any other information ive been super frustrated with this.
 
Doing a Windows 10 Repair Install or Feature Update Using the Windows 10 ISO file

You say you've done the DISM (first) and SFC (second) pair and they didn't work. If you did not try these in that order, please follow these instructions before trying what I listed at the outset: Using DISM (Deployment Imaging Servicing and Management) and SFC (System File Checker) to Repair Windows 8 & 10

If you can't get a Repair Install to work, then it's either starting a new topic on the Windows Update forum (and see the posting instructions there prior to doing so) or resorting to a "nuke and pave:" Doing a Completely Clean (Re)install of Windows 10 Using Media Creation Tool to Fetch the Win10 ISO File
Since you would have already downloaded a fresh copy of the ISO file to attempt a repair install/feature update you can ignore the steps in this tutorial for doing that and continue at the step immediately after the download.
 
I ran SFC first and DISM last, but I will try in your order as well as do a completely clean my system, ill keep you updated.
 
My advice at this point is to try the Repair Install/Feature Update instructions using the ISO file. Ideally I would do this while you have no internet connection and also making the choice given not to download the latest updates. Those will be downloaded after the repair install/feature update is complete, if it works, and avoids needless complication during that actual process. I gave the direct link to the downloadable tutorial I've written on doing this. As previously noted, if you already have a FRESH (as in not more than a couple of weeks old) copy of the ISO then just pick up in the instructions after the steps to download it. If not, then start from the very beginning.

I do not ever go the "thermonuclear option" of a completely clean reinstall unless a repair install/feature update from downloaded media has failed. And you can also try starting a topic in the Windows Update forum if the repair install/feature update does not work if you have enough data and programs (and the time associated with same, and customizing your computer to your liking) before resorting to a nuke and pave.

This situation again points out why it is so critically important to take full system image backups on a routine, cyclic basis for anyone who owns a computer. Things can go wrong that, ultimately, cannot be fixed and will require a nuke and pave, where you lose everything. It is just so much faster, and way less stressful, to do a recovery from the last full system image you have and have your entire computing world be exactly as it was when you took that backup.

How to Choose the Right External Backup Drive for You

Why you MUST Routinely Take Full System Image Backups of Your Computer

In the age of SSDs, which are great until and unless they die without any warning (and, believe me, they do), and have an astronomical data recovery cost, that second statement and the tutorial it downloads is more true than ever!
 
Hey so, if I choose Create Installation Media and try to create a Virtual Disc i get an Error when trying to mount it and when i try to repair by choosing the repair now option it says unable to complete installation of windows 10. At this point I am probably just going to go to a computer tech place and get them to redownload windows for me cause I can't considering i cant mount or even plug in a USB cause of "unavailable drivers". Until then I will keep trying with any methods I find or hear about.
 
What do you mean by "Creating installation media?" If you can boot into Windows 10 you should not have to create installation media, which is precisely the poing of the ISO technique. You right click the ISO file, choose "Mount" from the context menu, and a File Explore should open and away you go. If that's not happening then you'd need to burn the ISO to a USB drive and use that instead or use the Windows Media Creation tool to directly create the USB bootable media then just kick off setup.exe from the USB drive.

The technique I gave you in the tutorial does not use an external drive. The ISO is on your system disk wherever you put it and you use the Windows 10 mount command. No drivers are involved. That's the whole point.

Please read and follow the instructions as written and you should have no problem. Your DISM and SFC having come back clean should ensure that much. Whether the whole process succeeds when run is a separate issue, but mounting the ISO and kicking off setup.exe should always work if you can boot into Windows at all. If it really doesn't, then you really do need to either start a topic in the Windows Update forum or do a nuke and pave completely clean install.

At this point I can't assist any further unless a specific error occurs. I've given every method I know of, one that does not use external media, but an ISO file sitting on the main drive, and another that does. If neither can be used to kick off a repair install/feature update, I'm dead in the water.
 
I cannot mount the file it says cannot mount. And I also cant get a USB plugged in because it doesnt show up. In input it says drivers unavailable but i have tried installing recent usb drivers and still doesnt show up. I will just bring my computer into a repair place or some because ive been trying and researching for the past 4 days and havent fixed anything. Is there any way I can just delete windows off of my system so they can reinstall it via USB ?
 
You don't have to delete Windows 10 off your machine.

I've given you the set of downloadable instructions for doing a completely clean reinstall. If you need to use a friend's computer to create the install media then that's what you'll have to do. In this instance, that's almost certainly what you'll have to do as far as creating USB install media.

If you cannot boot from USB media after having done whatever your BIOS/UEFI requires to do that, you have an issue that goes well beyond Windows. Windows drivers don't even enter the picture when clean (re)installing. Everything is controlled by system BIOS/UEFI.

Doing a Completely Clean (Re)install of Windows 10 Using Media Creation Tool to Fetch the Win10 ISO File

Doing a Completely Clean (Re)install of Windows 10 Using Media Creation Tool to Create Bootable Win10 Install Media on a USB Thumb Drive

I'd suggest using the Media Creation Tool on someone else's machine to create your USB boot media and then following the rest of the instructions from there.
 
Status report, please?

That can be anything from, "I've dropped this," or, "I haven't gotten back to it yet," to, "I took it to a shop and it's been fixed."

When things go from "hot and heavy" to dead cold the readership (and your assistant) wonder what's occurred.
