How to fix this two problem related to administration privilege?

Question

Hello, I've recently encountered with some problems such as "To continue, enter admin username and password" and "Access is denied". My pc only have one account (which is my local account but not admin account) and I have no idea how to fix this. It started when I changed it from Adminstration to Standard because I tried to find some ways to gain a permission to the admin and I tried to follow other guides however those didn't work, hopefully you could help me with these problems.

Answer 1

On this computer, it doesn't have an admin at all, or it has an admin, but you don't know the password?

If it doesn't have admin at all, there's a way to recover admin access.

Hold down Shift key while you choose Windows restart, then go to Troubleshoot > Advanced Options > Startup Settings, click on restart, then choose option 4.

When prompted for password, leave it blank and enter.

When you are in safe mode, hold down windows + r keys, type in netplwiz and press enter.

Then double click on your username, go to Group Membership tab, make it admin.

Restart, log back into your user. You should now have admin access.

Answer 2

Hi,

It seems that you have inadvertently changed your admin user account to a standard account. To verify that, please open Command Prompt and run these commands:

whoami /user

net localgroup administrators

Post the output in your next reply.
