IS the OEM the opearting systgem that was insalled by the vinder like when buying from Dell the Dell company must put the system no need to buy the operating system.
Hey @Abdullah-khalaf , you are correct OEM stands for Original Equipment Manufacturer. OEM's have a special relationship with component and software manufacturers. You mentioned Dell, I used to support Dell-based platforms and when we deployed a set of Optiplex 745 and 960s we had the option to have the OS preinstalled. This would be considered an OEM version of Windows. However we had a WDS(Windows Deployment Services) server on the network so the Dell machines we received were called a "bare-metal" deployment, meaning no OSs were preinstalled on the machines. We deployed the OS as the second part of the deployment process, the first part being the physical installation of the PCs. I hope this helps and keep the questions coming!
