Having now upgraded three computers to Windows 10, I thought that I would share my documented steps. It is based on a blog by Tom Warren, which I have expanded and I hope clarified.
How to upgrade to Windows 10 without waiting in line
Microsoft is providing a free upgrade to Windows 10 for Windows 7, 8 or 8.1 users, via the normal upgrade process. Here is a way that you can avoid the wait and upgrade to Windows 10 straight away and optionally create a clean Windows 10 installation disc/drive. You have 12 months to do this for free, following the release of Windows 10 on July 29, 2015.
Firstly, back up all your files and data just in case. If you're on a 32-bit version of Windows, then download the 32-bit Media Creation Tool, and if you're using a 64-bit version, then grab the 64-bit Media Creation Tool. You can check your Windows version by right clicking on My Computer or This PC in File Explorer and going to properties, and it will be listed under system type.
Run the tool and then select the “Upgrade this PC now” option. Windows 10 will start downloading, and once it's ready you'll be presented with three options: keep personal files and apps, keep personal files only, and nothing. Select the first option (keep personal files and apps) to ensure your PC upgrades and you keep your files and applications. Windows 10 will start installing and after a few reboots and customisations (and a few hours if you are on a slow internet connection) you'll be upgraded. If you decide you want to go back to your previous Windows installation, then you can safely restore by going to settings > update & security > and choose the option to go back.
If you want to be able to re-install Windows 10 from scratch, find the Windows 10 installation key that was allocated during the free upgrade, by using Belarc Advisor or other tool. Also note the version of Windows you now have (Home or Pro, 32 bit or 64 bit). Now create your Windows 10 installation media using the Media Creation Tool once more, but this time choose “Create installation media for another PC” and download the appropriate version as identified above. Note that the Windows Key has been authorised for this upgraded computer, and probably will not work on a different one. It should, however, work for both 32 bit and 64 bit versions of Windows 10 on that computer, but not both Home and Pro versions.
The above procedure involves the time consuming download of Windows 10 twice: firstly to upgrade your PC and secondly to create your reinstallation media. You can skip this second process if you like, but you cannot avoid the first if you want a free upgrade to Windows 10 (i.e. free installation key).
