Windows 10: I have lost the administration option and Windows Security

I have been trying to install a program that required stopping the real-time protection i think it got some kind of crack or something like that, so I did, then I got the blue screen then my computer restarted, and I found that I can't 'run as administrator', i got a notification 'turn on windows defender...' when I looked up for windows security I found out that I don't have Windows Security Service anymore, I tried 'DISM' solution and 'sfc' from answers in this website, but nothing worked,I can't run CMD or PowerShell as administrator or anything anymore, so I 'CD' to system32 folder.

Administrative Privileges lost on Windows 10

Wrote some steps here on how to regain lost administrative rights in Windows.

Fix Lost Administrator rights in Windows 11 and Windows 10 - Your Windows Guide

1. Perform a hard shutdown two times during the Windows boot screen. On the third time, Windows should boot to the recovery environment. You can also press and hold Shift+click Restart on the lock screen to open Windows Recovery.
   
2. Click Troubleshoot on the screen. Then choose Advanced options>Start-up Settings.
   
3. Select Restart.
   
4. Press 4 to launch the computer in Safe mode.
   

Afterwards, Windows should log you into your standard account. From there, type netplwiz in the Run dialog box. You should now see a prompt asking for the superuser admin account password. The password is usually blank, and clicking yes without entering anything should do the trick. If that does not help, try entering the password of your user account that has lost administrative rights.

Now, the next step is to regain lost administrator rights. For that, double click the username to open its properties.

Next, click the group membership tab.

From Standard user, change the membership to Administrator and click OK.





The user account would now have administrator rights restored.

 

Lost all Administrator permission

Hello,

I have lost all my administrator permission. I have two profiles but both profiles are standard. I have tried every option that were listed on existing forums. Every option leads me to a pop-up screen stating I have no permission. Are there any other recommendations?
