If your desktop or laptop is currently running activated Windows 8.1, Windows 8 or Windows 7 and you want to perform a clean install of Windows 10, you could take the instructions below to upgrade your computer to Windows 10. After Windows 10 clean installation is complete, we recommend you to backup Windows 10 to external hard drive in case of data loss, disk failure, BSOD, etc. If you have clean installed Windows 10 on your HDD but later would like to install Windows 10 on SSD for better performance, you can use AOMEI Partition Assistant which allows you to migrate OS to SSD without clean install Windows and applications.
