Unlike Windows 95 and 98, Windows Vista hides the product key using encryption, which means a manual search in the registry doesn't work.

Finding the product key is important when installing, reinstalling or activating Windows Vista. If the original product key is truly lost, buying a new copy of Windows Vista may be necessary.

Original computer manufacturers may also offer new product keys for their computers that came with pre-installed Windows.Learn more about Software
