The Command Prompt in Windows is the command-line interface program that is used to execute some low-level software or issue commands directly to your computer. The interface is very similar to the old Disk Operating System (DOS) that PCs used before the Windows operating system, and uses DOS syntax.

Some commands that change the basic functionality or licensing level of Windows require additional access privileges to execute. To run these commands, you will need to use an Elevated Command Prompt, which is the regular Command Prompt with Administrator-level access rights. You will need to know the username and Windows password of an account with full Administrator access rights before you can use the Elevated Command Prompt.

1. In the System Tray, click Start or the magnifying glass icon.
2. Type cmd but do not press Enter.
3. In the Best Results section, you should see Command Prompt.

4. In the list of options under the Command Prompt application, click Run As Administrator.

5. If a User Access Control window opens, log in using Windows user account with Administrator access rights.

An Elevated Command Prompt window should now open, ready for you to enter commands.
