Windows 10: microsoft account disppaer from window login screen after I delete NGC folder

I have been using a PIN to log into my Windows system for several years, which I initially set up during the installation. Yesterday, I attempted to update my PIN but discovered that the option to do so was disabled under Settings -> Sign-in options -> Windows Hello PIN. In order to resolve this issue, I searched through forums and followed a suggested solution to delete the NGC folder.Then I attempted to update my PIN by going to Settings -> Sign-in options -> Windows Hello PIN. However, after entering the new PIN twice and clicking submit, it prompts that there is a problem and t

I deleted NGC Folder, now can't login.

When I tried to change Windows Hello Pin, it showed an error 'your organisations resources dontupport this pin'. I checked microsoft tech community and one microsoft officer replied delete NGC folder by taking permission and I did so. After that i got new pin setup but i thought it's about setting new user so i restarted. But now i can't login.

It's showing login in link when I click it it returns back to lock screen. And it repeats for all account even admin as all accounts used hello pin for login.

I need a fix for this as it not my fault. I can't reset the OS or delete accounts I need to get it back.

 

User account missing from login screen

I cant log in to my main user profile.

Previously I had an issue where I was getting notifications saying to set up Windows Hello, although I already had a pin, and when I tried to create a pin, it would ask for my pin to verify identity then the window would just close. This was the same if I tried to make a pin through Windows settings. I tried to find a solution online and most forums and the likes, including on Microsoft Answers said to delete the contents of the Ngc folder in C:\Windows\ServiceProfiles\LocalService\AppData\Local\Microsoft\Ngc, which would rest pin data and allow me to remake it and Windows to realise this.

Initially it seemed to fix the issue as I did this on my user account and I was now able to set up a pin through Windows settings, however I tried to first relog then restart my PC (just to make sure it worked) but when I tried to log in again, my user account was gone from the login screen, and the only account was the default Windows Administrator account which I had enabled anyway.

From the Admin account I can see my user account, and before restarting it even said it was still logged in, but on clicking on it, it still just takes me to the Administrator login screen with no way to change user.

I tried multiple system restores to even a few days before this happened, but that didnt restore Ngc, and even said that documents werent affected by the restore. I also tried to navigate to where it should've been, and used the 'previous versions'
tab from properties. Here theres actually an older version from before it was deleted but I cant restore or view it, because whether I try to open Ngc directly or from the previous version of the parent folder, access is denied. I cant copy the file or change the permissions or its owner, if I try that I get an error message saying 'The media is write protected', and I cant enter or copy the folder from powershell (if I open the 'previous version' folder and shift right click to open powershell'.

The only way I have managed to in any way get inside the previous version of Ngc was through git bash which I already had on my PC. With that I can do right click>open git bash here, and I can navigate the contents of the Ngc folder and verify that this 'previous version' does actually have all the files.

so just to recap: I deleted the contents of Ngc to reset my pin. I cant restore it through system restore which leaves it unaffected. Although I know previous versions of the folder do contain the deleted files, I have no way to restore them, copy them or save them anywhere on my PC.

Is there any way I can still restore these files, or make Windows re-create them from scratch?

All my user specific files are still there, and the user still exists, I just cant log on to it.


I'm on Windows 10 2004, build 19041.450
