By default users need to use their Microsoft Account to upgrade or install Windows 10 Creators Update, so it requires your information such as Outlook.com, Hotmail, MSN, or Live ID email address and password. Microsoft Account can sync various internet-based credentials, such as installed apps, Start screen, appearance configurations, and Edge/IE favorites. If you don’t need those cloud features or just test the new OS, the best way is to use a local account for that.

* First you need to create a bootable USB drive or installation DVD. It requires a USB flash drive with at least 4GB free space for the 32-bit version and 8 GB for the 64-bit version. Plug the USB drive in to your tablet or computer, and get the ISO of Creators Update file.
Download the free utility Rufus and open the Rufus.exe file to run.
