If you don’t have a product key, you can’t activate your Windows. But the problem comes when you want to reinstall Windows 7 / 8 / 10 on your computer or notebook, and you don’t have a genuine product key. While most of us will never try to retrieve the product keys as the Windows image provided with the computer will automatically retrieve the product key from the BIOS or EFI during the operating system installation. However, it may be seen by entering the BIOS/EFI of your computer. After purchasing these branded PCs, you will not find any sticker on the computer or battery way with product key information or Certificate of Authenticity (COA) sticker.

All new branded Windows computers are preloaded with Windows 11, Windows 7, Windows 8, or Windows 10.

With the release of Windows 7 OS, all PC manufacturers have started securing product license keys into the BIOS/EFI.
