Windows 10: Only admin account is appearing and i can't find mine

Only one account appears the admin account before we had three and now its only one how can I get my account back

:)

 

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:

 

Corrupted Admin Account (Mine)

An alternative/suggestion...………….
Logon to your "only user account" > open Elevated Command Prompt. You will be asked for your admin credentials. Enter your admin password.
At the flashing Elevated Command Prompt, enter this ………
net user Administrator /active:yes
> press Enter.
That will enable the Built-in Admin Account.

That done, hit Restart or Switch User > select the Built-in Admin Account and login by hitting Enter key ( by default, it has no password.)
Now you can create a new admin account for yourself. Use it for a few days to make sure it is ok. If satisfied, delete the old corrupted admin account.
If you want to keep the built-in admin acct, give it a password.
If not, disable it by entering the following to your elevated command prompt.....……………
net user Administrator /active:no
> Enter.

Refer to this tutorial for details : Enable or Disable Elevated Administrator account in Windows 10

 

Problems with Adobe Lightroom appear to be from corrupted User Account

Mickey,

Yes, just do step 2 if you already know that the test account behaves correctly.

Step 1 was just to confirm the state of play because it would be reckless for me to suggest that you take away Admin status from what might have been your only Admin account.
