Administrative.
To run a single command with administrative privileges using a Domain User account, you can use the "Run as administrator" option by holding the Shift key and right-clicking the application or command prompt. Alternatively, you can use the "PsExec" tool from the Sysinternals suite, which allows you to execute commands with elevated privileges. Another option is to use the "runas" command with the appropriate credentials if you have access to an administrative account.

Administrative privileges
The program that allows you to use the secondary logon service to launch individual programs and utilities with administrative privileges is called "Run as." This feature is commonly found in Windows operating systems, enabling users to execute applications under a different user account, typically with elevated permissions, without needing to log out and switch accounts. Users can access this by right-clicking on an application and selecting "Run as administrator" or by using the Shift + right-click context menu option.
You can't. The only way to bypass access privileges without having administrative privileges is via bugs in a program already running with administrative permissions. Since most programs aren't (or shouldn't be) run with administrative privileges, you can't rely on 1.) a program to be running with high privileges, and 2.) for it to have unpatched bugs. If such a bug was known, it would become patched fairly quickly (at least in the case of Linux).
As many as you have users with administrative privileges.
