Windows 10: who's defaultuser100001

I recently activated an account and logged into itit took too long to log in so I clicked the "X" because it logged me outI have no idea why it was a window instead of the normal OOBE now when I type "net user" in the command prompt it says that there's a user called defaultuser100001it says that the account is active but recently I checked and I am not able to log onto it

:)

 

A new User automatically formed on my laptop named Admin~1 and took all my admin powers. When I opened users a new user was created named "defaultuser100001"

I just opened my laptop today and there I saw a new user made named "Admin~1". After that, I could not access admin files. In "This Pc" I went to users and saw there was a user named "defaultuser100001". Did I get hacked?

Please help me and please tell me a way to fix this.

 

After 20H2 default user login is broken - Microsoft account popup on every PC login - accumulating defaultuser directories

Since I installed the 20H2 update on my PC a login to the system (after a boot or after locking the screen) always takes around one minute.

I am using a Microsoft account to login.

This is what happens:

- On my login screen my name and photo are shown, below is a text "Login" (I just translated that from German so it might actually have a different name)

- when I click on the text this is what happens:

- both screens go black and the signal is temporary lost

- then after many seconds in black the blurred background of the login screen shows up

- after many seconds the "Microsoft account" popup (just like with Office) pops up

- a couple of seconds later the keyboard slides in

- then I have to enter my password (the account is already set)

- after that the screen goes black again for many seconds

- then a blue screen with a white text and a spinner appears asking me to wait

- then after a total of 45 to 60 seconds I am finally logged in

This happens with any login and is extremely annoying as I have not found any way to fix it. Also, there seems to be nobody else on earth with this problem.

I just found out that what happens is this:

- when this happens a new folder is created under c:\Users - they have accumulated thus far:

defaultuser100000

defaultuser100000.{PC Name}

defaultuser100000.{PC Name}.000

defaultuser100000.{PC Name}.001

defaultuser100000.{PC Name}.002

defaultuser100000.{PC Name}.003

defaultuser100000.{PC Name}.004

defaultuser100001

defaultuser100001.{PC Name}

defaultuser100001.{PC Name}.000

defaultuser100001.{PC Name}.001

defaultuser100001.{PC Name}.002

defaultuser100001.{PC Name}.003

defaultuser100001.{PC Name}.004

Which each login one is added. I am sure that this will continue as long as Microsoft does not fix something.

What I found out already is that these folders *should be* leftovers from an update. However, they are created on each login.

I have read that I can delete them but I fear that if I do this I might not be able to login again as Microsoft seems to think:

1. I am the default Windows user and I have a Microsoft account

2. I am not really logged in

Disabling or enabling the login credentials for Microsoft updates in the Windows settings changes absolutely nothing.

So I think this is a hiccup where something from the update is left over that needs to be fixed.

I think only Microsoft can help here.

Thanks!

Hey Derrell, from what I can tell, you seem to be having a User Profile situation. I don't have much experience with multiple user profiles but maybe you do understand where the problem might be. Searching the Registry for the SID numbers may help find info.
