I get a popup that says "You need administrator privileges to ~".

Question

When I try to coby a file into a system folder or delete a system file or folder I am getting a popup saying "You must have administrator rights to ~".
Is there any way to get rid of this pop-up?

It didn't appear until a previous (2-3 ago) build.
The only thing I changed was to change autounattend.xml to attend.xml. Up to previous builds (2-3 ago), I had a clean install with autounattend.xml in the root of the USB, but in recent builds, for some reason, it freezes at the first screen of the install when autounattend.xml is in the root.
So I put autounattend.xml in "C:\Windows\System32\Sysprep" and installed it.
The contents of autounattend.xml and unattend.xml are the same.

I am not sure if this is the cause of the popups.

The user account control setting is set to not notify at the bottom.
The group for installation is set to Administrators.
The name is set as my name.
The version is 22H2 build 22623.1180.
