How to upgrade win8 to win 10

Most folks will tell you to use Windows Update -- and while that is the easiest, it is also the most unreliable and has the most failures.  A far better way, which does involve more work, is to use the Microsoft Media Creation Tool (MCT) to download and create Windows 10 install media on a USB stick, and then do an in-place upgrade from that media.

Here is how to so that ...

- Use this link to download and create Win10 install media: https://www.microsoft.com/en-us/software-download/windows10

- insert that into your PC (do NOT boot from it), find the folder containing the media, select the setup.exe file, right-click that and select Run as Administrator.  This will start an in-place Upgrade which could then take a couple of hours to complete.

If you are presented with a window asking for a product key, down near the bottom is a entry you can click to skip that. Do NOT enter a product key, as it will reuse your existing key and when you finish and get back online, Windows will automatically activate.
