I've previously used Magical JellyBean's KeyFinder. It functions adequately. https://www.magicaljellybean.com/keyfinder/ The free version suffices for retrieving Windows keys you've manually entered for activation. If none are present, it may be tied to your Microsoft account, meaning you likely don't need it. When reformatting your computer, it should automatically reinstall itself once you're in Windows and online—just avoid entering the key during setup.
When purchasing a pre-made system from companies like Acer, Dell, or HP, the product key is embedded in part of the BIOS chip on the motherboard. For a custom-built PC, the key isn’t stored there and can be lost if you reformat the drive. I wish there was a method to keep the key in the BIOS, similar to what OEMs provide. Usually, I print the key, fold it up, and place it inside the case near the side panel or inside the back panel of the case. If you need to change hardware, Windows might raise an issue. One of my PCs had a non-retail key, and after replacing the motherboard and CPU it became unactivated. I had to contact a Microsoft support line, explaining the situation as a hardware failure. They asked me to repeat the activation sequence, claiming it was needed because the license was an OEM key meant for single-use on one machine.
On Windows 10 and 11 it depends on the hardware. If you were already set up on a specific device, even after reinstalling, it will turn active again. If it doesn<|pad|>, use the activation troubleshooter and mention you changed hardware. It helps if your Windows is connected to a Microsoft account, and you can always restore your installation.
