This may be old hat, but it was news to me. A free Windows 10 upgrade is still available from Microsoft. With support for Win 7 scheduled to end in January, I decided to upgrade my home machine to Win 10. Since the widely-publicized deadline for the free upgrade ended in 2016, I assumed that I'd have to pay for a license. But then I ran across this: https://www.zdnet.com/article/heres-how-you-can-still-get-a-free-windows-10-upgrade/ If you're upgrading a single machine, you can go here: https://www.microsoft.com/software-download/windows10 Click "Download tool now"; after the download completes, run the Media Creation Tool. The first time I started Windows 10 it failed with an "invalid user profile" error. This was fixed simply by restarting Windows. I then encountered the dreaded "Windows has loaded with a temporary profile" message -- meaning that any changes to the Desktop and settings are lost when you log out. An easy Registry edit fixed this. So, my factory- installed edition of Windows 7 Home was successfully upgraded to the Home edition of Win 10. But then I remembered that I owned a legal copy of Win 7 Professional, which I had only ever run in a virtual machine. I entered the product key and, sure enough, a few minutes later I was running Win 10 Pro. -- Carl Distefano cld@xxxxxxxxxx
