Windows Hello PIN Something went wrong. Try again later

did you try restarting your computer? I don't know if it will work for you but it did for me. I tried two methods (shown bellow). Method 3 worked for me until I got to the DWORD named value part, because it was already set as 1. So, a few hours ago the first thing I did after I turned my computer was to check my windows hello pin. and like you I Already had it set up. After I got the "something went wrong" pop up I restarted my computer and the "set up your windows hello pin" DIDN'T appear. I then checked my settings and "add" was gone, in stead was "Change and Remove."

I hope this helped.

"Method 2: Using Group policy settings if you have Windows 10 Pro installed.

If you are on Windows 10 Pro edition, you can change the group policy settings to enable PIN sign-in option for all users.

1. Open the Run dialog box by pressing the Windows key and the R key together.
2. Type GPEDIT.MSC and hit the Enter key.
3. Go to Computer Configuration -> Administrative Templates -> System -> Logon.
4. On the right side, double click on Turn on PIN sign-in and select Enable.
5. Similarly disable the other Windows Hello options if any.
6. Exit the Group policy editor and reboot the computer.

Method 3: Using Registry settings if you have Windows 10 Home installed

If you are on Windows 10 Home edition, you can change the registry settings to enable PIN sign-in option for all users.

1. Open the Run dialog box by pressing the Windows key and the R key together.
2. Type Regedit and hit the Enter key.
3. When the Registry Editor opens, navigate to the following location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\default\Settings\AllowSignInOptions.
4. In the right pane, double click on the DWORD entry named value set it to 1."

Try my solution 🤷‍♂️

After freshly installed Windows with new ISO offline installer of newer Windows 10 update, I faced with the same problem (cannot setup PIN).

I did nothing. After ignoring for a while, the problem automatically resolved by itself.

So the history from problem to problem solved is like,

1. Fresh install Windows but cannot setup PIN.
2. After all Windows updates, restart. Still cannot setup PIN.
3. None of the 3 methods worked (Aditya_Roy's reply on 13/4/2020).
4. After multiple restarts, a few days on-and-off PC, still cannot setup PIN.

One day, I leave my PC on and idle for quite a long while (a few hours), then it so happened when I re-try setting up PIN, and PIN was successfully setup.

No clues why it happened that way; maybe something is running at background (to finish the updating process??) when I left my PC on and idle?? I don't know.

Hey, 

I tried using the methods mentioned below but run couldn't find the application locations for method 1&2 however, method 3's location was found and reset values to 1 but it was still not working.

I found useful the task about deleting "ngc" folder in C:\, though i had to make it like 3 times before it worked the right way
