Windows 7 Downgrade to genuine?

Hi Sean, I'm sorry to hear about your experience with the unauthorized copy of Windows 7 Ultimate. It's understandable that you want to rectify this situation and move to a genuine copy of Windows Home Premium without having to reinstall the entire operating system. Fortunately, it is possible to change the product key in Windows 7 without reinstalling the OS. Here's a step-by-step guide on how you can do this: 1. Purchase a Windows 7 Home Premium Product Key: - You can purchase a legitimate product key for Windows 7 Home Premium from authorized retailers or Microsoft directly. 2. Changing the Product Key: - Navigate to the Control Panel. - Go to "System and Security" and then click on "System." - Scroll down to the section titled "Windows activation" and click on "Change product key." - Enter the new Windows 7 Home Premium product key that you have purchased. - Click on "Next" to activate Windows with the new key. 3. Activation and Verification: - After entering the new key, Windows will attempt to activate online. If successful, your copy of Windows will now be genuine. As for your concern about running a 64-bit version of Windows 7, the version of Windows (Ultimate, Home Premium, etc.) does not affect whether it is 32-bit or 64-bit. You can install both 32-bit and 64-bit versions of Windows 7 for any edition. By following these steps, you should be able to switch from Windows 7 Ultimate to Windows 7 Home Premium without the need for a clean reinstall. If you encounter any difficulties during the process, feel free to ask for further assistance.
