Microsoft has provided it for download. In our final post, we saw how you could use it to create installation media. In this article, we will see how to use it to upgrade a Windows 8.1 or Windows 7 computer to Windows 10.

If you upgrade to Windows 10, the new operating system will get your product key and activation details from your previous operating system. They are stored on Microsoft servers along with your computer details.

If you cleaned Windows the first time installed, you might face activation problems. If you upgrade for the first time, activate Windows 10, and install Windows 10 on the same computer. There will be no activation issues as the operating system will pull activation details from Microsoft’s servers.

So, if your Windows 10 is not activated, we advise you not to do a clean install for the first time. The first upgrade, activate, and then clean install.

You may want to back up your important data to an external drive before proceeding with the upgrade. Also, make sure you have a Windows login password. And although you don’t need it during the upgrade process, you should find and download your Windows product key somewhere.

Clean install Windows 10

If you want to clean up the Windows 10 installation on your computer, burn the Windows 10 ISO with the Windows 10 Media Creation Creation Tool to create an installation media. Make sure the BIOS settings allow you to boot from USB. Plugin the USB and restart the computer.

Upon restarting, your computer will boot from the USB drive, and the installation will begin. This process is more or less the same. However, you will be asked to choose a system drive and or if you want to format the drive.
