Windows 10: Lost admin rights to a random windows account

Hello,So the other day I noticed my only account on my laptop had lost administrator privileges to a random account that mysteriously appeared. The new random account has a password which I don`t know I tried guessing a few and also tried no password and it doesnt work. Basically I can´t do anything beside use things I already have installed. I did try going to safe mode but it won´t let me before I pick an account, and I can only pick my own without admin rights. I also can´t use cmd or any command in it. I googled for days and only find few similar cases of ppl describing it happend to the

:)

admin rights keep disappearing!?!!

Hi guys,

I am actually having a problem at work that our IT department hasn't been able to figure out. I am supposed to be a member of the admin group. We are on a domain. The problem is that everytime I reboot the computer I loose my admin rights(no longer in the administrator group) and just become a normal user again. I have tried googling this and didn't get to many results.
I believe IT is just giving me local admin rights, not admin rights for the whole domain.

Any suggestions?

EDIT: It is on Windows XP Pro.

Hello Rick, my name is Marco and I am an Independent Advisor. I will do my best to help you.

You can recover your admin rights through safe mode.

Follow these steps from your account which was admin before.

-right click on Windows Start button and go Settings.

-Click on " Accounts"

-Select "Family & other users", and then click "Add someone else to this PC".

-Click "I don't have this person’s sign-in information." and "Add a user without a Microsoft account."

-Enter a username and "NEXT", A local account will be created

-Click on start button and type CMD

-In the Command Prompt Windows, type: shutdown /r /o

and press Enter

-After Windows 10 restarts to the "Choose an option" screen, click Troubleshoot > Advanced options > Startup Settings. Then click Restart.

-On the Startup Settings screen, press 4 number key to enable safe mode.

-Go to User Accounts > Manage another account, select the new local account you created

-then click the Change the account type link. Select Administrator and click Change Account Type to change the account from a standard user to an administrator.

-Restart PC to get Windows 10 out of safe mode and go back to its normal mode. Sign in Windows 10 with the new Admin account. Now, you’ve got back administrator rights in Windows 10 and you can delete the issued Admin account on which you lost administrator
rights.
