This post shows students and new users steps to find their Windows 11 product (activation) key. Microsoft uses a product key to verify the authenticity of a Windows license. To abide by Microsoft Windows’ licensing terms, a full (retail) version of Windows should only be installed and used on one computer.
The activation (product) key is there to ensure that Windows is not being installed on more than one computer at the same time. That’s why everytime you installed Windows, you’ll be asked for a product key to activate it. If the product key is being used on other computers, you may be allowed to activate it and Windows will not work until activated.
You can transfer your full (retail) license to another computer and will still be able to get support from Microsoft, but you will have to deactivate and uninstall the product key on other computers before you’re allowed to reuse it.
Before you deactivate and uninstall Windows product key, you may want to take notes of the key if you’ve forgotten it. With the key handy, you can then uninstall it from other computers so you can reinstall.
