Windows 10 Upgrade from Windows 7 ERROR : Media Creation Tool - error code 0X80072F8F - 0X20000

Media Creation Tool - error code 0X80072F8F - 0X20000

I have a Dell computer from 2011. I'm trying to upgrade from WIN7 to WIN10.

I got an error message when trying to run the MediaCreationTool21H2.exe. It says to reference the error code 0X80072F8F - 0X20000. Any suggestions would be appreciated.

Some server that the MediaCreationTool21H2.exe tries to talk to apparently no longer speaks the old TLS 1.0 security protocol, but Windows 7 SP1 still has the newer TLS 1.1 and TLS 1.2 disabled by default, resulting in this error code right at the start. So I had to first run the “Easy fix 51044” MSI to make a few registry changes to enable the more recent TLS versions, and then Media Creation Tool - error code 0X80072F8F - 0X20000 no longer appeared.

The newer operating system booted from the installation ISO image won't have that TLS-version limitation, so using that should be another solution to the same problem.
