• How to Upgrade from 32-Bit to 64-Bit in Windows 10. The 64-bit version enables you to use more than 3.75 GB of RAM, providing you with a faster Windows 10 experience. Moreover, 64-bit Windows 10 requires NX support as standard, gifting your processor another layer of protection from malicious attention.
• If you want to perform a clean install of Windows 10 Creators Update, you can download Windows 10 Creators Update ISO (32-bit or 64-bit) using the official Windows 10 Media Creation Tool. The Media Creation Tool, as you likely know, in addition to downloading ISO, helps you create bootable USB of Windows 10.

Follow these steps to create installation media (USB flash drive or DVD) you can use to install a new copy of Windows 10, perform a clean installation, or reinstall Windows 10.

Before you download the tool make sure you have:

• An internet connection (internet service provider fees may apply).
• Sufficient data storage available on a computer, USB or external drive for the download.
• A blank USB flash drive with at least 8GB of space or blank DVD (and DVD burner) if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted.
• When burning a DVD from an ISO file, if you are told the disc image file is too large you will need to use Dual Layer (DL) DVD Media.

Check a few things on the PC where you want to install Windows 10:
