Originally created by @connormcdermid on GitHub (May 8, 2019).

Noob question: I seem to be able to get an administrator command prompt without confirming that I am, in fact, a system administrator (I am not).

I am running Windows 10.0.17134.706

I open conhost.exe from the Run dialog (Win + R) or from the start menu

An administrator command prompt opens without prompting me for an administrator password (my account is not an administrator account) (cmd line prompt is C:\WINDOWS\system32>
I tested this by running a command that would require administrator privileges to execute:
net user xxxx /active:yes and received output The command completed successfully.

This seems like a rather large security flaw; while I don't think this is a widespread issue (might be a bug with my version), I'd like to know if I can fix this.
