Windows is definitely the widely used operating system across the globe. If you had purchased a computer or a laptop with Windows 7 pre-installed, the Windows 7 Product Key label will be stickered on your computer. Alternatively if you had purchased Packaged software (Windows 7 Home Premium, Windows 7 Professional or Windows 7 Ultimate), you will be provided with the Windows 7 Product Key that can be used while activating your copy of Windows 7.

If you are looking for your Windows 7 Home Premium Product Key or Windows 7 Professional Product Key or Windows 7 Ultimate Product Key, you can find your product key on your computer or inside the Windows package or in a confirmation e‑mail if you purchased and downloaded Windows 7 online. If you had lost your Windows 7 Product Key or the Windows 7 Activation Key, there are many applications over the Internet that will help you to recover Windows 7 Product Key. Also remember that Windows 7 Product Key will be different with each of the product versions. For example, your Windows 7 Product Key cannot be used to activate Windows 8 and you should buy your Windows 8 Product Key for that. Also if you have got a Windows 8 Product Key, you cannot use the same to activate Windows 8 Pro or Windows 8 Enterprise.
