Windows 7; free upgrade to Windows 10

It is now known that Microsoft's free Windows 10 upgrade offer never stopped working. Yes, if you do not know, there is another way to activate Windows 10 with a Windows 7 key, or 8.1.

While Windows 7 is still one of the best options for having a stable Windows system, the upcoming end of support (tomorrow, January 14) may make you think about upgrading to Windows 10. Of course from iGuRu .gr we suggest more radical solutions such as the installation of an easy Linux distribution, (see MX, Ubuntu, Mint KDE), many are the ones who insist on Windows.

Microsoft's offer for a free upgrade to Windows 10 from an older operating system has been in effect since Windows 10 was first released in 2015. It looks like this offer is still valid, even though the company has state the opposite.

Below we will see how you can get Windows 10 with the old legal installation key of Windows 7, 8.1. The process is easy. First, you will need a Windows 7, 8 or 8.1 key.

Create a Windows 10 installer if you do not already have one. You can do it easily with Windows 10 media creation tool of Microsoft.

Select "Create installation media for another computer" and the tool will allow you to create a bootable USB drive or burn a bootable DVD. Install Windows 10 properly.

You can perform an upgrade installation that retains existing files or a clean installation that deletes everything from your old system. When prompted to enter a key, enter the Windows 7 key, or 8.1.

The installer will accept the key and the installation process will continue normally. (If you are using a Windows 8 or 8.1 system that has the product key built into the UEFI or BIOS firmware, you may be able to click the "I do not have a product key" button.

Windows 10 will automatically find the UEFI key and activate your system.) After installing Windows 10, follow the path Settings - Update & Security - Activation and you should see that your computer has a digital license. If you did not provide a key during the installation, you can add it now (we are always talking about a legitimate Windows 7, 8 or 8.1 key).

Windows will check in on Microsoft servers and give your computer a digital license for Windows 10.
