Windows 10: User account activation

I accidentally deactivated all my user accounts no I can't use my win 10 laptop .what should I do?

:)

 

Current active users that are friends

The other reason I suggested this is that users can add characters to their username that are not alphanumeric (e.g. user*). This confuses things somewhat when looking at the list.

 

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Windows 10 start up user account

Hi Jim,

Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

I understand the inconvenience you are facing with log-in user account, we will help you to resolve this issue.

Kindly provide us with the following information to assist you better:

• How many user accounts are there on your computer?
• Is your computer connect to Domain?
• Were you able to see your another user account on start-up screen?

If you are able to see another user account on start-up screen, I suggest you to login through that account and enable the built-in admin account.

After enabling the built-in admin account you can login through that account and delete the default account.

Step 1: Steps to enable built-in admin account

Try to login to your temporary user account, enable built in administrator.

• • Press Windows + X key together on your desktop screen.
  • Click on Command Prompt (admin) to open Command Prompt.
    
  • Type the following command and hit Enter:

net user administrator /active: yes (Check for the spaces)

4. Now log off from the current user and try to login to the administrator account that is enabled.

Note: Please follow the same steps and type net user administrator /active: no to disable admin account after the troubleshooting is done.

Step 2: Steps to delete the account:

• 
  Login with the built-in administrator account.
  
• 
  Press “Windows key + X" from the keyboard and click on
  Search icon.
  
• 
  Type Control Panel in the search box, click on “User accounts” and on
  "Manage another account"
  
• 
  Click the on the default account you want to delete and Delete.
