Temporary fix to 'Your program License doesn't permit support maximum N non-demonstration companies'

Introduction:
While I was testing InterCompany Setup, I faced an issue probably a limitation of the CRONUS standard license which comes with standard NAV/ BC On-Premise installations.
Whenever I created new multiple Companies in NAV, I got an error 'Your program License doesn't permit support maximum N non-demonstration companies'.

Pre-requisites:
Microsoft Dynamics NAV 2018.
Microsoft Dynamics 365 Business Central.

Solution:
I faced this error when I restarted NAV Client after creating a non-evaluation company. Thus, I cannot remove the company from front-end. I tried using Microsoft Documentation and found that it was actually possible (YAY!! 😁). Refer https://docs.microsoft.com/en-us/dynamics-nav/how-to--delete-companies.
Instead, it kept ruining things more. The Server Instance would stop without any errors and NAV Windows Client would infinitely work trying to connect to the workspace.
Finally, I found that using Windows Powershell with NAV Management module where it was possible to delete the Company from the back-end.

NOTE: 
1. The database shouldn't be in Single user mode.
2. The NAV Server Instance should be in RUNNING state.

Powershell Commands and Outputs:
Recreating the error by creating new companies.

Creating a new Company!

Changing to the new Company!

Importing the NAVAdmin Powershell module which comes in the package when you install NAV/ BC On-Premise.

Getting the list of Companies on the NAV Server Instance using PowerShell

Removing the Company for a particular NAV Server instance

Conclusion:
I tried going into single user mode to delete the company from NAV Windows Client but it didn't work
