Why does Windows say "No access" when copying files even though I'm an admin?

Question

Windows

Win10 2004.
I can't understand the logic:
Here I am copying a file from drive D to the root of drive C.
I get a message that admin rights are needed for copying, such as there is no access, I poke "Everything with admin rights ...." and only then is copying.
Doesn't the OS understand that I am the admin, and if it doesn't understand, then why doesn't it ask to confirm admin rights, for example, by asking for a password? Why is this incomprehensible protection needed? How to disable?

or

Answer 1

The OS understands that now everything is around with admin rights and everyone is *diots. So it asks for confirmation so that you don’t * rni bells and whistles.
But seriously, Windows runs software with limited rights, including Explorer. This is done to increase safety from crooked hands.

Answer 2

Do not store files in the root of the drive. Create a folder and everything will be OK.
For a long time, the rights to the root of the disk have been special so that viruses do not sit there, and the user has more order.

Answer 3

Explorer (and indeed all Windows applications launched at startup) is not launched as an administrator, but because if we create files, folders, etc. through it, it cannot create a file / folder where it is prohibited.
This is such a protection against crooked hands
. It seems that this cannot be bypassed.
