Distinguish between OEM keys and regular ones.
Hey! The main difference is that an OEM key comes from the original manufacturer and works perfectly with Windows 8.1 Professional, while a normal key is usually for retail or third-party purchases. It’s important to get the right type to ensure compatibility and proper functionality.
OEM keys are usually tied to the specific hardware they're installed on. This means your license only applies to the individual system you're using. If you set up a new machine and attempt to use the OEM key, it might not function properly. The Windows 10 upgrade requires an OEM-style key, which is what I should keep in mind during the process. I wouldn't recommend upgrading to Windows 10 if you intend to perform a significant hardware overhaul within the next year or so.
