Hello there, I appreciate you taking the time to read through and answer my question.

I have actually tried the Microsoft App Troubleshooter before to try and solve this question, and I am unable to run it. The app gives me the error "Microsoft account required." In fact, pretty much none of the account features work
on my Windows 10 machine. I can't add accounts, change to local user, or interact in any way with any of the settings under "Change Account Settings." So this problem is obviously more severe than I had previously thought. My PC should be up to date with Windows
updates, as I have it set to automatically download and install updates for me, but I checked just in case, but I don't think the Windows update feature is working for me either, as the windows says "Checking for updates" and has done so for almost an hour
now. I checked the changelog, and it seems to be installing updates as normal, as the last update was performed on August 9th, 2017.

So it seems there's either a grave error with this instance of my Microsoft account on just this PC, or my Windows 10 installation is corrupted.

Hi,

As we thoroughly reviewed your conversation with the previous support, this proves that the issue has something to do with the corrupted user account data. For us to isolate the issue, let's create a new user account by following the steps provided on the
link below.

If it works using the new account, this indicates that this is caused by a corrupted user data. We suggest transferring your data to the new account. Here are the steps:

1. Press Windows + X keys.
   
2. Select File Explorer.
   
3. Choose This PC and double-click Local Disk (C.
   
4. Click Users.
   
5. Copy all the folders inside the old user profile to the new user profile.
   
6. Restart your device and sign in to the new user account.
   
7. Check if you can see all the files you've copied. Your new user account should look like your old one. However, you'll need to change the desktop background.

I'm unable to sign in because I receive this error code whenever I try to sign in or download a profile. Same error code everytime. Doesn't matter if I'm using a wired or wireless connection, it's the same error code.

I have been unable to sign into the Xbox app, any help would be appreciated.
