It does sound like you've pinned the elevated command prompt instead of the standard user prompt.
To check this, right-click on the taskbar icon, then right-click on the "Windows Command Processor" option, and click the "Properties" option. The field that matters is the "Start in" field (if the properties menu doesn't automatically open there, this is under the "Shortcut" tab). The "Start in" field should read "C:\Windows\System32" or "%HOMEDRIVE%%HOMEPATH%". If it reads "C:\Windows\System32", it's probably running as admin by default.
I would recommend altering it to the aforementioned system variables "%HOMEDRIVE%%HOMEPATH%". If you're uncomfortable with that, unpin it from the taskbar, then, using the search bar in the start menu, search for "command prompt". Pin that to the taskbar & it should run as a standard privilege user.
An associate of mine had the same issue recently.
