The following example teaches you how to determine whether the Windows license you are running on your computer is OEM, Retail, or Volume.
When it comes to purchasing a Windows, there are a number of different ways to do it. Depending on the method you choose, the licenses come at a different price, as well as with different rights, restrictions, and names. The most common license types are Retail (FPP (Full Packaged Product)), OEM (Original Equipment Manufacturer), and Volume Licensing.
For more information, see this link to Microsoft
Volume Licensing.
They are aimed at companies of all sizes that wish to purchase at least 5 software licenses by choosing one of the flexible pricing schemes, simplifying license management and enjoying additional benefits depending on the product (e.g. license portability, right to downgrade and use older versions, etc.).
Pre-installed software (OEM/DSP)
Pre-installed software is available in DSP/OEM format and has been created with the purpose of a) being pre-installed on new PCs and servers exclusively by computer/server manufacturers for the purpose of resale, or b) accompanying the computer or server on which it was originally installed by its manufacturer (System Builder or OEM Manufacturer)
Retail Packages (Retail/FPP)
Retail / FPP (Full Packaged Products) packages are available through retail stores and are aimed at both home users and very small companies up to 10 PCs. They allow installation and use of the software on 1 device. The package includes the product activation key number and a storage medium or link to an online location for installation.
But let's now see how to determine if your Windows has been activated as Retail, OEM, or Volume.
1. Open a command line. To do this, press the Win + R keys simultaneously and in the run window that appears, type the word “cmd” and press Enter
2. Type the following command in the command line, and press Enter.
slmgr -dli
3. After a short interval of 5 seconds the Windows Script Host dialog window will appear showing what type of license you are running. (See the images below):
