In this article, we are going to look at resetting the Rearm of our Windows 2016 Server.
Windows allows up to 5 Rearms per installation. Once you meet this quota, you will be shown an information dialog letting you know that you have no more Rearms available and that you will have to reinstall the Operating System in order to gain the Rearms back.
In most cases, this can be a major issue, especially when you are working in a lab or school environment where you have students who depend on these servers being up and running.
