The easiest way to find a lost Windows product key is to download a free key finder program and have it automatically search your computer for your Windows product key.
These key finder programs are great for finding lost keys from operating systems like Windows 7, Windows Vista, Windows XP and more. Many also find lost CD keys from Microsoft Office and other programs.
Most users looking for a way to find Windows product keys are trying to locate the one used for their Microsoft Windows installation.
However, if you're looking for a product key for an older operating system and you'd rather not download unfamiliar software to help with your hunt, there are some manual ways to locate the product key:
- Find the Windows 95 Product Key Code
- Find the Windows 98 Product Key Code
- Find the Windows ME Product Key Code
If you still can't find your Windows CD key, you may need to purchase your version of Windows all over again.
