Upgrade to Windows 10 from Windows 7 or 8.1 - for free

Notes: This updated content (@ 2019) is based on the most recent public release of Windows 10, version 1809 released to the public on October 13, 2018.

During 2017,  Microsoft offered a 'free upgrade' to Windows 10 for users on Windows 7 and 8. That "free offer" option ended on the 31st December 2017.

What qualifies for a update to Windows 10?

The good news is that even in 2019 (last tested on April 2019) you can still upgrade to Windows 10 on a device that has (or access to) a valid license for Windows 7 or Windows 8.1 (it can be Home Premium or Pro). You  can download the required installation files (as an ISO) and run the Setup program from within Windows or use the Upgrade Assistant available from Microsoft's accessibility page. See the Microsoft link here for the download section for Windows 10.

What does not qualify:

Desktops and Laptops that have a product key (license)  to run the now outdated Windows XP or Windows Vista are not eligible for any type upgrade to Windows 10. In this scenario the only option is to purchase Windows 10.

Where can I download Windows 10?

You can use the download link here.

If you already have a Windows 7 product key (very likely if you have a few older computer about the house - see image above) or you are planning to reinstall Windows 10 on a machine that already has a valid (activated) Windows 7, use the Get Windows 10 download page and download the ISO or use the Media Creation Tool.

Windows 10 Update Now - or Download Media

Use the Update Assistant to manually download and install the latest Windows 10 feature update.

This event downloads a small pre-installation file that runs a compatibility check and then, once the device passes the compatibility tests, it begins the full upgrade.

Upgrading a existing Windows 7 or 8 device

If you upgrade over a activated copy of Windows 7 or Windows 8.1, you can simply run Setup from within your current Windows installation and you will not be prompted to enter a product key. After the upgrade is complete, your new copy of Windows 10 will be activated with what Microsoft calls a valid "digital license".

Upgrading over a valid Windows 7 or 8 sytem will allow you to retain nearly all of your programs and data intact.

Upgrade Keeping Personal Files and Apps

The only notable point if to consider upgrading any MS Office installation older than 2013 to a later version. It has been found that while the older Word 2007 runs well enough under Windows 10, Outlook 2007 or 2010 do have some known usabilty issues with the newer OS. Other than this, you should findmost of your original programs remain intact.

Note that some printer drivers may need updating to restore full operation with Windows 10.

Performing a clean installation

If you choose to use the bootable installation Windows 10 media to perform a clean install on a computer that was previously upgraded to Windows 10, you are not required to enter a product key, so when you see the prompt to enter the a key, you may click the Skip this step option (thought enter the original Windows 7 key it if you wish).

Notes: On a Windows system that received a Windows 10 digital license as part of its earlier upgrade (during the "Windows 10 for free" period of 2017), Windows 10 will be automatically activated after the installation is complete.

If you are using bootable installation media to perform a clean install on a PC that has never been upgraded to Windows 10 and activated, you will need to enter the Windows 7 or 8 product key. 

Notes: Beginning with the Windows 10 build 10586 (released November 10, 2015), you can enter a product key from a matching edition of Windows 7, Windows 8, or Windows 8.1.

After the activation is complete, you can continue to perform a clean install using the Windows 10 installation media.

Checking the Windows 10 Activation

To check the activation status of a Windows 10 device, use Settings > Update & security > Activation.

An activated Windows 10

After a some basic questions at the beginning of the upgrade, the remaining Windows 10 upgrade process can be left run completely unattended. This part of the process will likely require about 5 - 8 hours.

Then the privacy settings are shown explicitly, with brief explanations of what they do.

Windows 10 Privacy Settings - Default

For your personal privacy sake I would use the following recommended privacy settings

The one privacy setting that cannot be turned off completely is the MS Diagnostics (unless you have a Enterprise Windows 10). Regardless, such diagnostics allows Microsoft to collect data on app performance and crashes, and this data can be used to correct issues with Windows, apps, drivers, and this is useful. You can, however, choose basic or full diagnostics.
