+Note that WopiHost will always be compatible only with the latest version of OOS because Microsoft also [supports only the latest version](https://learn.microsoft.com/officeonlineserver/office-online-server-release-schedule).
 
 The deployment of OOS/OWA requires the server to be part of a domain. If your server is not part of any domain (e.g. you're running it in a VM sandbox) it can be overcome by promoting your machine to a [Domain Controller](https://social.technet.microsoft.com/wiki/contents/articles/12370.windows-server-2012-set-up-your-first-domain-controller-step-by-step.aspx).
 To test your OWA server [follow the instructions here](https://learn.microsoft.com/office/troubleshoot/administration/test-viewing-documents-by-using-office-online-server-viewer).
 To remove the OWA instance use [`Remove-OfficeWebAppsMachine`](http://sharepointjack.com/2014/fun-configuring-office-web-apps-2013-owa/).
