After creating a second administrater user account with an existing MS account, the new desktop starts with Dock display of short cuts including Edge, Trash etc. Could find no refference to this display.

After I sign off from the new account, I signed in to my original account and found several Desktop shortcut icons gone.
Even the program DesktopOK 4, which restores previous desktop icons, would not work. It has worked before on W10.
Have done warm and cold reboots to no avail. I have repeated this operation after running Restore Point and had the same result.

How can I create a new account to be a mirror of my primary account (all settings and desktop duplicated)?
How do I keep this creation from affecting my original account Desktop?
