How to Make a Clean Windows 10 Upgrade Install and How to Download Windows 10

You can’t make a clean install until you upgrade first time your Windows 7 or Windows 8 copy from Windows.

Here is how to do it:

1. Go to this page https://www.microsoft.com/en-us/software-download/windows10
2. Download the appropiate Windows version 32-bit or 64-bit using the Microsoft Media Creation Tool.
3. Choose upgrade and install the upgrade over your existing activated Windows 7 or Windows 8.
4. After you finished the upgrade, go to Settings->About and see if your Windows is activated, if not, then try to check for updates, or do manual activation (without entering any key).
5. After Windows 10 is activated then you can make a clean install by downloading again the Windows Media Creation Tool and create a bootable DVD or USB stick.
6. Boot the Windows 10 installation from your USB stick or DVD.
7. Install Windows 10 normally, because it won’t ask you anymore for a Windows 10 CD KEY.
