People can still upgrade to Windows 10 on computers running Windows 7 or Windows 8.1 as long as they have a valid license for either version of Windows. Microsoft users can consequently still claim a free digital license for the latest Windows 10 version.

Windows 10 is one of the world most popular operating systems, boasting approximately one billion users.

Microsoft’s free Windows 10 upgrade offer supposedly ended almost four years ago.

But despite this, people can still upgrade to Windows 10 from Windows 7 or Windows 8.1

Users can also upgrade Windows 10 Home to Windows 10 Pro via a product key from an old business edition of Windows 7, 8, or 8.1.

Following these precautionary measures, navigate to the Download Windows 10 webpage and click the Download tool button.

However, those who wish to upgrade to Windows 10 on more than one PC should choose another option.

This step involves saving the installation files to a USB drive or as an ISO file.

Although this download takes a little longer, you can run the Windows Setup program manually to install Windows 10 on any PC running any supported Windows 10 version when it is ready.

The exact steps depend on which of the two download options you chose:

USB flash drive: Insert the USB flash drive you just created into a free USB slot on the PC you want to upgrade.

Next open File Explorer and double click Setup to install Windows 10.

You cannot boot from the newly created USB drive or DVD to perform an upgrade to Windows 10.

You must run the Windows 10 setup program from your currently installed and activated copy of Windows.

ISO file: After the download is complete, mount the ISO file and open it in a Windows Explorer window.

On a PC running Windows 8.1 or Windows 10, double-click the ISO file to open it as a virtual drive.

On a PC running Windows 7, install a third-party utility such as the free, open-source WinCDEmu.

After mounting the ISO file, double-click Setup to start the install process.

Now simply follow the prompts to complete the upgrade to Windows 10.

You will not be requested to provide a product key and when the upgrade is complete and you have connected to the internet, you should receive a digital license to the most recent Windows 10 version.
